China’s government has spent hundreds of billions of dollars to invest in new industrial parks with
the intent of boosting the economic growth, by attracting new firms into the parks and also generat-
ing spillovers for the local economy. Do such place-based investments in capital raise urban productivity
or is this another case of the powerful state misallocating capital in China? This paper measures the
localized spillover effects of 110 parks built in eight major cities on firm productivity, wages, and local
manufacturing employment growth. We find that the geographic spillover effect of parks is an increasing
function of the park’s overall human capital level, the FDI share, and its “synergy” with nearby incum-
bent firms (measured by Marshallian factors). Using geo-coded data, we document that the growth in
local employment and wages stimulates nearby local housing construction and retail store openings. The
rise of a new production sub-center causes the emergence of a suburban “consumer city”.

1. Introduction
Over the last twenty years, place-based industrial policies have
been a crucial component of the development strategy pursued
by the Chinese government. China’s local officials have allocated
millions of acres of land and made huge capital investments to
create industrial parks. As of 2006, there were 1568 national-
level and provincial-level industrial parks distributed in more than
270 Chinese cities, with 9949 square kilometers in total. Although
these parks only occupy around 0.1% of China’s total land area,
they contribute to about 10% of China’s GDP and one-third of
FDI. Several studies have explored China’s industrial parks and

heir positive impacts on local economies using a macro approach
Wang, 2013; Schminke and Van Biesebroeck, 2013; Alder et al.,
016 ). These studies use city level panel data and a difference in
ifference estimator to estimate the local effects of new parks. Lu
t al. (2016) use firm data and observe positive effects of industrial
arks on capital, employment and output within the park’s bound-
ry.
The spatial agglomeration literature has emphasized that such
pillovers are often highly localized (see Rosenthal and Strange,
0 03, 20 04 ). This literature suggests that the spillovers of China’s
ew industrial parks are likely to be localized within a city. Based
n this point, we will test for the effects of new parks on local
roduction activity and on consumer behavior in a close proximity
o the new parks. These new parks tend to be built at the edge
f a metropolitan area, with special land, tax, financial and eco-
omic policies to recruit highly productive firms. Physical prox-
mity between firms who seek to co-agglomerate facilitates lo-
al economic growth through stimulating trade by lowering trans-
ortation costs and by facilitating learning and social interaction
Combes et al., 2011 ). Moreover, these new industrial parks stim-
late economic growth by solving a land assembly problem and a
ross firm co-ordination problem and allowing firms to cluster to-
ether in a timely fashion in the context of China. These benefits
re more difficult to be reaped in developed world cities featured
ith pre-existing durable structures and with thousands of firms

1 Industrial parks are authorized by different level governments: state, provin-
cial, or prefecture (or below) government. Those parks authorized by the state
and provincial governments enjoy more favorable policies, such as lower interest
rate loans, larger tax, land price and utility price discounts. We only focus on
those parks because many of the lower-level industrial parks did not obtain for-
mal approval from the central and provincial governments and violated the rele-
vant laws and regulations. In 2003, the central government investigated industrial
parks regarding their potential violation of land use regulations and this resulted
in a large number of those lower-level industrial parks being abolished (see Cartier
(2001) and Adler (2013) ). 2 For the incumbent firms within the park’s boundary which had been estab-
lished before the park was introduced, generally they are unable to enjoy the favor-
able policies unless the park’s administrative committee (AC) re-sign an agreement
with them and change their registration status. Our interviews with some AC offi-
cials show that the latter case seldom happened.
ho do not fully consider the agglomeration externalities when
aking their individual location choice. Successful parks will at-
ract skilled workers who will seek a short commute to work. This
reates an incentive for developers and retail store businesses to
pen up quality housing and shopping close to the new parks.
herefore, a new edge city emerges.
Our study builds on recent work that has documented the het-
rogeneous effects of place-based policies ( Faggio et al., 2017 ).
everal studies have examined the role of place-based policies
n U.S local and regional growth, and their general conclusion is
hat those place-based policies do not lead to net growth ( Rossi-
ansberg et al., 2010; Kline and Moretti 2013; Neumark and Kolko
010 ). As we report below, we find that 70% of the new indus-
rial parks built during 1998–2007 in the eight major Chinese cities
enerate positive TFP spillovers in their vicinity, while 30% of those
arks turn out to have negative or insignificant TFP spillovers.
This paper uses detailed within-city geocoded micro data to
tudy the consequences of Chinese local governments recent in-
estments in industrial parks. We document both the agglomera-
ion benefits within a park’s geographic area and those spillover
ffects beyond its boundary. To test for the extent of the local-
zed agglomeration spillovers, we merge together several geocoded
ata sets in eight Chinese major cities. These cities are the home
f 110 state- and provincial-level industrial parks. We test whether
he creation of industrial parks is associated with production and
onsumption agglomerations based on key outcome indicators in-
luding: TFP for incumbent firms, local job and wage growth, new
ousing construction, home prices, and retail opportunities. Our
pproach allows us to study the economic incidence of this pub-
ic policy and builds on U.S work such as Busso et al. (2013) .
hese outcomes directly benefit the local government officials be-
ause their fiscal revenue is tied to the commercial and resi-
ential land sales, and also the tax collected from productive
rms.
Our study builds on the research estimating localized produc-
ivity spillover effects. Most agglomeration studies focus on the
nited States (see Rosenthal and Strange, 2004; Arzaghi and Hen-
erson, 2008; Greenstone et al., 2010 ). Our new estimates of the
o-agglomeration effects build on the estimates from developed
ities generated by Ellison et al. (2010) . If place-based policies,
uch as industrial parks, help to reallocate labor and capital to its
ighest and best use, local economic boom is likely to emerge.
Our work builds on the consumer city literature which used
ata from the United States to highlight the emergent consumption
pportunities available in cities ( Handbury and Weinstein, 2015;
iamond, 2015; Glaeser et al., 2001 ). The birth of a large industrial
ark creates a spatially concentrated center of employment and
urchasing power far from the city center. Many of the workers in
he park and at the expanding firms located close to the park will
eek out housing and shopping opportunities nearby. This creates
profit motive for retailers and housing developers to co-locate to
upply such goods ( Waldfogel, 2008 ). We demonstrate that such
ositive accumulative forces appear in the suburbs of China’s ma-
or cities when new parks are created.
To investigate the causal effect of an industrial park on local
conomic growth, we follow Greenstone et al. (2010) identifica-
ion strategy of conducting a difference in difference approach for
eographic areas who “won” and “lost” in luring a place based
reatment to their area. Industrial parks are not assigned to geo-
raphic locations at random. A mayor chooses whether and where
o build a park and then recruits firms to locate in the park. After
hese events have taken place, the local benefits (both production
nd consumption opportunities) unfold. To mitigate the concerns
f bias arising from park site selection, we create a control group
y identifying geographic site candidates for industrial parks based
n urban planning documents from the 1950 s to the early 1980 s.
hese candidate areas that were not selected to become industrial
arks form our control group.
Using micro data-based approach, we further test for a rich
et of such heterogeneous effects, and study the key mechanisms
enerating such spillovers. We find evidence of heterogeneous
pillover effects such that older parks, state-level parks, parks that
eature a higher human capital level, a larger share of FDI firms,
smaller share of State Owned Enterprises (SOEs), and a higher
o-agglomeration level of industrial composition, and parks with
better “fit” with the local incumbent industries (in terms of
tronger input-output linkages, labor market pooling, and knowl-
dge spillover) have larger agglomeration effects.
The rest of the paper is organized as follows. In Sections 2 we
ntroduce the institutional background and our conceptual frame-
ork. Section 3 describes data, empirical models and identification
trategies. Sections 4 and 5 present our main results and hetero-
eneity estimates, respectively. We conclude in Section 6 .
. Institutional background and conceptual framework
.1. Institutional background
We focus on the parks authorized by the state or the provincial
overnment in China. 1 Being a host city of such parks has become
favorite strategy of city mayors to compete for FDI and to foster
ocal economic growth ( Wu et al., 2013; Zheng et al., 2014 ). These
arks are approved by the state and provincial governments but
ost of them are implemented at the city level.
China’s industrial parks are opened in a two-step process. First,
city government initiates an industrial park program accompa-
ied with two general packages of policies. One is that city gov-
rnments make large capital investments to improve the trans-
ort infrastructure, utilities, storage, and other service facilities.
he other is associated with a bundle of preferential policies (see
ang, 2013; Alder et al., 2016; Lu et al., 2016 ) including: (1) tax
eductions: corporate income tax rates of 15% −24% as opposed to
he 33% firms normally pay in China are available to foreign enter-
rises, technologically-advanced enterprises, and export-oriented
nterprises; (2) discounted land-use fee and utility prices: to at-
ract productive firms, industrial parks set low land transfer fees
s well as utility prices (electricity, water, etc.), and also favorable
ayment methods; (3) special treatment in securing bank loans:
tate-owned banks put priority on and offer favorable interest rate
o the loan applications from the firms in industrial parks; (4)
aster and easier administrative approval for firm registration for
xporting and importing. 2
Secondly, city mayors are likely to use the “managed hand” to
romote the industrial park policies. China’s unique political sys-
em grants city mayors with powers that far exceed their West-
rn counterparts. On the one hand, the city government represent-
ng the state owns urban land. They can easily convert agricultural
and at the edge of cities into urban use. Moreover, they have the

power to allocate a large parcel of land to build an industrial park
and engage in land assembly in ways that are impossible in the
United States. Given that Chinese mayors increase their promotion
chances by raising local economic growth, they have strong incen-
tives to pursue pro-growth strategies. However, this may also bring
in the risk that some city mayors are not smart enough, or they
are too aggressive, so that they make the wrong decision and over-
invest in parks.
Third, the recruitment process in industrial parks is always op-
erated in the lower administrative committee level on behalf of the
city government. The administrative committee in the industrial
park takes the responsibility to direct and to administer the park –
such as project approval, local taxation, land management, finance,
personnel, and public service provision. Private negotiations take
place between the administrative committee staffs and the poten-
tial entrants regarding the exact bundle of subsidies each firm will
receive if it agrees to enter the park. These negotiations lead to
a set of firms choosing to enter the park and then we observe
the subsequent outcomes both within and spilling over outside
of the park. Such recruitment process bears a close resemblance
to the anchor tenant recruitment challenge that arises in creating
a successful shopping mall ( Pashigian and Gould, 1998; Gould et
al., 2005 ) and the development of U.S suburban planned towns
( Henderson and Mitra, 1996 ). The mall owners gain profit from
activities within their mall. If there are positive spillover effects
from a mall to the local community, the mall owner has no claim
to those. But in the Chinese case, the city mayor is in charge of
the entire jurisdiction (including the center city and the new city
around the park) and thus internalizes all of the possible spillover
effects generated by an industrial park . While Chinese mayors
seek to engage in pro-growth strategies, industrial parks are risky
and costly. Below, we will document evidence of significant het-
erogeneous treatment effects induced by these investments.
China’s mayors face capital constraints. In choosing whether
and where to invest in a park, city mayors face a trade-off between
a stream of benefits an industrial park offers and the upfront and
opportunity costs of establishing the park on a large plot of land. 3
The city mayors tend to raise funds through various channels in-
cluding debt financing. 4 In 2011, the total fixed asset investment in
131 state-level industrial parks was 2092 billion RMB yuan ($332
billion US dollars), which was about 35% of the total fixed asset in-
vestment in the whole nation. 5 According to IMF estimates, local-
government debt reached 36% of GDP in 2013, a doubling since
2008, and will increase to 52% of GDP in 2019. Global investors
have worried that such rising debt combined with the slowdown
of the Chinese economy could create a future debt crisis. 6 Such lo-
cal debt crises are less likely to take place if past investments yield
a significant flow of medium term agglomeration benefits.
3 Such farmland is owned by rural villages. If the city government (the upper-
level government of those rural villages) wants to build a new industrial park on
farmland, it needs to covert the use type of that land parcel from agricultural use
to industrial use, and compensate the rural villages who own the land. In most
cases the range of compensation for farmers for land taken is quite low because it
is often based on income generated in agriculture use instead of being tied to its
opportunity cost (the value of the land if allocated to urban use) ( Ding and Song,
2005 ). 4 On average, bank loans, land sale revenue and on-budget fiscal revenue account
for 28%, 25% and 33% of the sources of municipal infrastructure investment in China
in 2010, respectively, and the rest of the money comes from other non-bank finan-
ial channels. See: Ryan Rutkowski. Four Myths about local Infrastructure Invest-
ment in China. China Economic Watch, the Peterson Institute for International Eco-
nomics. http://blogs.piie.com/china/?p=3281 . 5 China Statistics Yearbook, 2012. 6 See http://www.wsj.com/articles/debt- that- once- boosted- its- cities- now-

.2. Local production and consumption spillovers due to industrial
arks
Here we provide a simple framework to motivate our empirical
pproach. Our starting point is that industrial parks attract produc-
ive firms, and also improve the productivity of incumbent firms
ocated close or within the park. There are two groups of incum-
ent firms – those within and those outside (but close to) a park’s
oundary. We are mostly interested in measuring the spillover
reatment effect on the incumbent firms.
Each incumbent manufacturing establishment in a city is en-
owed with a production function. All else equal, firms located
loser to the city center (where the main agglomeration takes
lace) are more productive. Once an industrial park is built, each
ocation within a city becomes two dimensional as we track the
lant’s distance to the city center and its distance to the closest
ndustrial park. 7 An incumbent firm chooses the amount of labor,
(priced at a competitive wage w ); capital, K (with input price p );
nd land, L (priced in the competitive land market with rent r ), to
aximize its corresponding profit �:
a x K,N,L � = f (A, K, N, L ) − pK − wN − rL
A is the productivity shifter (TFP), and is used to capture the
gglomeration economies this firm enjoys. Output’s price is nor-
alized to one. Here we allow agglomeration externalities, A , to
epend on the firm’s distance to the central business district (CBD)
nd the nearest park’s boundary A = A ( D CBD , D park ) . Where,
A/∂ D CBD < 0 ; ∂ A/∂ D park < 0 .
The positive agglomeration economies increase the productivity
f incumbent plants. This will lead to higher output, ∂ f / ∂ A > 0,
nd thus higher profit, which will trigger the entry or relocation
f firms who are interested in gaining access to such spillovers to
he vicinity of the park. Incumbent firms enjoying increased pro-
uctivity because of their proximity to the new park should also
e less likely to exit. The incumbent firms experiencing productiv-
ty growth will expand by occupying more land and hiring more
orkers. The growth of the park itself and the subsequent entry of
rms and firm expansion in the park’s vicinity leads to competi-
ion for inputs. Wages will be bid up in a vicinity of the productive
ub-center, thus we should observe a negative wage gradient with
espect to distance to the park’s boundary:
w/∂ D park = (∂ w/∂ A ) · (∂ A/∂ D park ) < 0 .
The increases in both employment and wage within and around
he park contribute to the rise in purchasing power, and thus cre-
te the “market potential” ( Hanson, 2005 ), which is the demand
ase for both the housing and retail markets in this new edge city.
Given that commuting is costly, and due to the fact that work-
rs earn higher wages in a vicinity of the park, there will be a
reater density of new retail openings and new home sales in close
roximity to this new employment center, and the house price will
lso be higher. We predict the effects of an increase in distance to
n industrial park as follows:
new home sales /∂ D park < 0
new home prices /∂ D park < 0
new retail opennings/∂ D park < 0
7 If a city has multiple parks, other parks will also have some effect on this plant.
In the empirical analysis we will construct a variable to measure this global impact
of all the parks in the city, but now we abstract from this and only consider the
closest park.

8 This information is provided by the Ministry of Land and Resources of China
(MLRC). 9 For those parks that do not have websites or public released information, we
contacted the local officials to obtain the boundary information. 10 The largest park is 64, and the smallest one of 0.2 square kilometers. If we
measure the distance from the centroid of a park to the corresponding city’s CBD,
the average park is located 24.9 kilometers away. The most remote park is 95.1
kilometers from the city center.
.3. Measuring park heterogeneity
There may exist significant heterogeneity in parks’ spillover ef-
ects. As we will document below, 30% of the parks we study gen-
rate insignificant or even negative local spillovers.
We seek to explain the determinants of park heterogeneous
reatment effects. We have collected data that allow us to differen-
iate the parks along four dimensions. The first dimension is based
n the cohort and age of the park. We allow for two cohorts –
lder parks established before 1998 and new ones established in
r after 1998. If the Chinese leaders selected better locations for
he earlier parks to set up growth engines in the country, a di-
inishing returns hypothesis would predict that older parks will
ave larger spillover effects than the newer ones. Within a given
birth cohort” of parks, we expect that the spillover effect grows
ith the park’s age. The second dimension of park differentiation
s the park’s administrative level – whether it is a state-level or a
rovincial-level park. The parks approved by upper level govern-
ent would enjoy more favorable policies packages such as lower
nterest rate loans, larger tax cut, cheaper land price and utility
osts, etc. Thus we expect that all else being equal, a state-level
ark would generate larger spillovers.
The third heterogeneity dimension is based on the likely syn-
rgies between the park’s tenants and local incumbent industries
easured by continuous economic distances between them. Here
ur “thought experiment” is to hold the park’s composition of
rms constant and see how it fits in different neighborhoods. Fol-
owing Glaeser and Kerr (2009), Ellison et al. (2010) and Jofre-
onseny et al. (2011) , we construct four metrics measuring the
ustomers and supplier linkages, sharing a large labor market, and
echnology spillovers between the incumbent firms in a vicinity of
he park and the tenants of the park. We expect that the park’s
pillover effect will be larger if these four forces are larger. In Ap-
endix B, we explain how we construct these metrics.
The fourth dimension is the park’s own composition of plants
nd industries. We hypothesize that a park will generate larger im-
acts if it is larger in size, closer to the CBD (thus stronger linkage
ith the city’s mean economic center), and features a lower share
f state-owned enterprises (SOE) employment, higher share of FDI
rms, higher level of human capital, and higher coagglomeration
etween the industries within the park (see Table 1 for variable
efinitions, and Appendix A for the construction of coagglomera-
ion index).
. Data and estimation strategy
Our study focuses on eight major cities in China: Beijing, Shang-
ai, Shenzhen, Tianjin, Dalian, Wuhan, Xi’ an and Chengdu. We
ave the micro data sets of manufacturing firms, real estate trans-
ctions, and retail shops in those eight cities. These cities include
ll three first-tier cities in China (Beijing, Shanghai, Shenzhen)
nd a couple of the top second-tier cities. We construct four key
eocoded data sets for these eight cities.
.1. Four geocoded data sets
.1.1. The spatial unit of analysis
Within a Chinese city, there are three levels of administrative
nits (from the upper to the lower level): district (or county),
iedao (“zone” thereafter) and juweihui (communities or villages,
small zone” thereafter). For instance, Beijing has 16 districts, 320
ones and 5274 small zones. In the eight cities, the average sizes
f a zone and a small zone are 47.9 and 4.1 square kilometers, re-
pectively. We know the exact geographic boundaries of industrial
arks and zones, but we only have the centroid of a small zone.
or all plants in our data set, we know their zone identifiers; and
or about 60% of them, we know their small zone identifiers.
We know the exact street address of all residential complexes
nd retail establishments. We create two by two kilometer grid cell
aps (the same area as the average size of a small zone) for all
ight cities. This allows us to count the number of new home sales
nd new retail openings by grid cell.
.1.2. The industrial parks data set
According to the 2006 “Bulletin List for the Official Boundaries
f Chinese Industrial Parks” 8 , there are 110 state- and provincial-
evel industrial parks in these eight cities (43 are state-level and 67
re provincial-level), accounting for 8.6% in all such parks in China.
rom the list we know each park’s name, location, and the year
his park was established. From the websites of industrial parks’
Cs we obtain the exact geographic boundary of each park. 9 We
hen geocode the exact boundaries for the 110 parks in the eight
ities ( Fig. 1 ). Each city has several industrial parks – Beijing has
1 parks, and Dalian has 8 parks. The average park’s size is 11.88
quare kilometers. 10
We define the parks established before 1998, the first year of
ur manufacturing plants data set (ASIFs) as “old parks”, and those
stablished during the ASIFs sampling period as “new parks” .
mong the 110 parks, 70 are “old” and 40 are “new” parks.
.1.3. The manufacturing plants data set (ASIFs)
We obtain plant-level data from the Annual Survey of Industrial
irms (ASIFs) dataset conducted by National Bureau of Statistics of
hina (NBSC) from 1998 to 2007. All the state-owned enterprises
SOEs) and non-state owned enterprises with annual sales of more
han 5 million RMB in the manufacturing sector are surveyed, with
etailed information on a plant’s identification, operations and per-
ormance, and all financial variables. Those firms hire roughly 70%
f the industrial employment, generate 90% of the industrial out-
uts and 98% of the exports ( Brandt et al., 2012 ). We link plants
ver time using their information on ID number, name, industry
ode, address (small zone/zone identifier), etc., and construct an
nbalanced panel of 64,759 plants in this ten year period for these
ight cities.
An advantage of this ASIFs data set (compared to the economic
ensus data set) is that it enables us to estimate plant-level total
actor productivity (TFP). We use the data on outputs and interme-
iate inputs, deflated by output and input price indices reported in
randt et al. (2012) , to calculate the real capital stock, real value
dded, and then estimate plant-level TFP (See Appendix A). The
econd key variable is the plant-level wage measure ( Wage ). This
ata set does not contain the wage records for individual work-
rs. Instead, it reports each plant’s annual wage bill and the num-
er of workers employed in each year. Thus we calculate the aver-
ge wage by plant by year. The third variable is the park-specific
o-agglomeration index. We follow Ellison and Glaeser (1997) ’s
ethodology in developing industry pair co-agglomeration index,
hich measures the extent to which the two industries tend to
o-locate in a certain area. Our park-specific co-agglomeration in-
ex is the weighted average of the bilateral co-agglomeration in-
ices for the existing industry pairs in the park (using employ-
ent in each industry pair as the weight). Intuitively, if those in-
ustry pairs that have higher co-agglomeration indices have larger

mployment shares in a park, this park will have a larger park-
pecific co-agglomeration index, which means that the industries
n the park enjoy a higher synergy level (see Technical Appendix A
or details).
We geocode each plant using its zone/small zone identifier. To
easure the spillovers of these industrial parks in their vicinity,
e map plants into industrial parks. We identify the plants inside
he parks and those outside. For those plants outside, we measure
dheir distances to the city center and to the park’s boundary within
city, respectively.

11 The impact area (where the spillovers exist) is likely to vary by park. For the
sake of simplicity, we estimate the average size of the impact area for all parks
and use it in our regressions. For each type of spillovers we have the corresponding
average impact area. We acknowledge this “averaging” may introduce some bias.
For instance, for some very productive parks, we under-estimate their impact area,
and vice versa. 12 “The closest park” is selected based on the distances from the plant to each of
the 40 parks in 2007. 13 We use a travel-distance algorithm written by John Voorheis to construct this
real travel distance measure. This STATA code is available on http://pages.uoregon.
edu/jlv/code.html . 14 In 1992, the Chinese State Council approved the construction of the “7-5” net-
work, which was completed ahead of schedule by the end of 2007 (see Faber
(2014) for details). The construction during that period was much intensive, so to
simply make this control we use the highway network by the end of 2007 to mea-
sure the accessibility.
the number of units sold by residential complex by month. Across
the eight cities, the number of observations varies from 80 0 0 to
40,0 0 0 complex-months. The physical attributes for each complex
include the floor area ratio ( FAR ), green space rate ( Green ), and the
ratio of parking space to the number house units ( Parking ).
Using data on the longitude and latitude of each residential
complex, we geocode all the residential complexes. We calculate
each complex’s locational attributes such as its distance to the city
center, its distance to the closest industrial park’s boundary, and
the 2 km by 2 km grid cell this complex is located in. We also cal-
culate the number of housing units sold for each grid cell in each
year.
We construct a dataset for local private consumption goods
based on dianping.com. a yelp.com in the US. The website covers in-
formation on twelve general categories of urban consumption ser-
vices, and the three biggest are restaurants, entertainment facili-
ties, and retail shops. For these three major categories, as of 2013
there were more than 874,0 0 0 retail establishments in these eight
cities . We know the establishment date for each shop. We geocode
them in the GIS maps and calculate each category’s count density
by grid cell (the data are reliable for years after 2005). Since our
housing and retail data sets only start from 2006 and 2005, while
our manufacturing firm data set is between 1998–2007, what we
observe is the ex-post outcomes in the housing and retail sectors
after the establishments of our sample industrial parks. The cover-
age of the consumption sectors in our study can help study the ef-
fects of an industrial park featuring high-tech companies that pro-
duce Internet services such as Baidu and Alibaba. Such effects are
ignored in previous localized spillover studies that focus on manu-
facturing plants.
Using a major industrial park in Beijing (“Beijing Economic and
Technological Development Zone” ) as an example, Fig. 2 shows the
above geographic units of analysis we use when doing the geocod-
ing work. Table 1 presents the variable definitions and summary
statistics. It also provides information concerning our various geo-
graphic levels of aggregation.
3.2. Econometric models
We seek to study the causal impact of new industrial parks on
the local economy. We hypothesize that the opening of an indus-
trial park will increase the TFP of incumbent firms, local wages and
the density of economic activity in and around the park. The lo-
cation of firms in an industrial park will lead workers to locate
nearby to keep commuting costs down. Workers will bid up price
of land, thus increasing local population density. This triggers in-
creases in local housing prices and new construction as well as
new retail store openings. Our empirical work will study each step
in this “chain” .
3.2.1. Baseline difference in difference specifications
We first focus on measuring the productivity spillovers of new
parks on incumbent firm productivity ( TFP ), incumbent firm wage
rates ( Wage ) and the density of manufacturing jobs in the close
vicinity from new parks ( Employment ). Since we are estimating the
productivity premiums of a geographic area (the park itself or the
park’s impact area) and we have two periods (before and after
the park is established), it is natural to employ the difference-in-
difference (DID) strategy. For the subset of 40 new parks built be-
tween 1998 and 2007 (the sample period of the ASIF data set), we
will employ the DID specification.
As shown in Fig. 3 , we define a dummy variable Park which
equals one for the firms (or zones/small zones, grid cells, housing
units) within the park boundary. Assume that the park’s spillovers
have an “impact area” which ends at x̄ kilometers from the park
oundary, we define a dummy ImpactArea to represent this area. 11
e will identify the average impact area for productivity spillovers,
ousing market spillovers and retail market spillovers, respectively.
dummy Outside is created to represent the area outside the im-
act area. The dummy After equals one for the years after the es-
ablishment of the park.
To be clear, we estimate two separate DID models. First, we
eep the plants within the new parks ( Treatment = Park = 1, treat-
ent group) and the plants in the outside area (the area outside
he impact area, Outside = 1, Treatment = 0, control group), then es-
imate:
it = α0 + α1 · T reatmen t i j + α2 · A f te r jt
+ α3 · T reatmen t i j · A f te r jt + β×X it + city F Es
+ dist rict −year t rend + indust ry −year F Es + μi + ε it (1)
here the subscript i, j, t refers to plant i , industrial park j and
ear t, respectively. For those plants within parks, After jt switches
rom zero to one after park j is opened in year t ; for those plants in
he outside area, After jt switches from zero to one after its closest
ark j is opened. 12 Second, we keep the plants in the impact ar-
as of the new parks ( Treatment = ImpactArea = 1, treatment group)
nd the plants in the outside area ( Outside = 1, Treatment = 0, con-
rol group), then re-estimate Eq. (1) .
In both equations, the control group is the plants in the out-
ide area ( Outside = 1 indicates that the plant is outside the im-
act area). The firms in the impact area will receive spillovers from
he park, and the park may also absorb the firm activities from
his impact area. So the firms in the impact area are not clean
nough to act as the control group. The key coefficient of inter-
st is α3 , which measures the premiums of the outcome Y for the
ark and the park’s impact area in the two equations, respectively.
n TFP and wage regressions, we include city fixed effects, district-
pecific time trends, and industry-specific year dummies. We also
nclude plant fixed effects ( μi ), so we are tracking the within-plant
FP ( Wage ) change of the incumbent plants which is attributed to
he introduction of a new industrial park. Note that the incumbent
lants within the park’s boundary which had been established be-
ore the park’s establishment, are generally not eligible for the fa-
orable policies (see footnote #1), but they do enjoy agglomeration
conomies brought by firms clusters in the park. This is similar to
hose plants in the impact area.
The vector X contains the attributes of firms, including the real
ravel distance to CBD (the driving distance based on the road
etwork in that city) from observation i to the city center, 13 the
lant’s size and age, and whether it is a SOE plant or a FDI one,
ts distances to the closest railway station, airport and university. 14
nother control variable in X is the influence from other indus-
rial parks, besides the closest park. We construct a variable ( Oth-
rParks ) to measure the “global” impact of all the existing parks
except the closest one) in the city. We use the market potential

In each year t , we identify all the existing parks in the city, and
he closest park j 0 . For all the parks except park j 0 , we use the in-
erse distance (in quadratic weighting function) from this plant i
o those parks as weights to compute the weighted sum of those
arks’ employment in year t . If a city has more parks and the plant
s relatively closer to those parks, we expect this plant will re-
eive more spillovers and thus have a higher TFP or wage. We will
ontrol for this “global impact” of other parks, and focus on the
pillovers from the closest park.
.2.2. The matched DID specification
In a city, industrial parks are not randomly assigned to loca-
ions. There are many unobservables (unknown to researchers) that
ary across locations. The validity of the above DID specification
Eq. (1) ) depends on the assumption that those unobservables are

identical between the treatment area (the park or the park’s im-
pact area) and the control area (the outside area nearby the park).
But this may not be true. For instance, infrastructure conditions,
such as transportation accessibility, electricity connection and the
sewerage system, may vary between the treatment and control ar-
eas. We employ the matched DID approach described below to ad-
dress this issue.
In a second set of estimation results, we follow Greenstone et
al. (2010) and implement their “winners and loser pairs” strategy.
We rely on old urban planning documents to identify a subset of
“similar zones” . Since the founding of new China in 1949, urban
planning in China had been greatly influenced by a “top-down”
command-and-control regulation system inherited from the former
Soviet Union, so it had been featured as state-led. In that central
planning era, urban planning was a major tool used by China’s
state and local governments to control and monitor urban infras-
tructure construction and production activities. The main goal of
1980 s urban planning was to facilitate the industrialization pro-
cess in China, based on the concepts of “industrialization without
urbanization” and “work first, live second” . The site selection of
future industrial zones (under different names such as “satellite in-
dustrial towns” and “industrial zones/areas” ) and the placement
of industrial projects were the key elements in the early waves of
“city master plans” .
Once some areas were selected as future “industrial zones” in
a city’s master plan, the city governments would make a large in-
vestment in infrastructure construction and land assembly, to en-
hance that place’s productivity potential. The city government also
had the power to relocate industrial plants to that zone or cre-
ate new plants there. With the input of such resources in several
decades, the industrial base of such zones had been well fostered,
and they became ideal candidates for “industrial parks” when
China initiated the new place-based policy of industrial parks in
late 1980 s and early 1990 s. In this new era, a city has to obtain
approval from the state or provincial governments to establish an
industrial park, so they cannot build as many parks as they want.
Only a portion of the early “industrial zones” set up in old city
master plans became industrial parks. Our interviews with some
senior principals in the municipal urban planning bureaus substan-
tiates our description of the industrial park site selection process. 15
This fact provides us the opportunity to identify the “winners” and
“losers” in this sample of early-defined industrial zones, in terms
of obtaining the industrial park “quota” . 16
Using the old city master plans from the 1950 s through the
1980 s for seven of the eight cities in our sample (Shenzhen is a
new city established in late 1980 s so this strategy does not ap-
ply to it), we identify 245 early-defined industrial zones, of which
about 40% became “winners” . These “winners” were selected to be
included in later developed industrial parks (in many cases a park
covers multiple early-defined industrial zones). Others are called
“losers” – they missed the opportunity to become parks due to the
limited quota of parks approved by the state.
15 In one of the interviews we conducted, Mr. Dong, the former President of Bei-
jing Urban Planning Design and Research Institute (a department within Beijing City
Planning Committee) told us, in late 1980s and early 1990s, the built-up area of
Beijing was small. The infrastructure condition in suburban Beijing was quite poor,
except for those early-defined “satellite industrial towns” (many of them were the
central towns of suburban districts/counties) with favorable infrastructure invest-
ment. Therefore, when choosing the location of a new industrial park, the urban
planning committee would prefer those “satellite industrial towns”. Given the re-
stricted number of new parks that could be built, only some of such “satellite in-
dustrial towns” were selected. 16 Among the 40 new industrial parks which were established during 1998 and
2007 in the eight cities, 30 industrial parks are in the “candidates” (early-defined
industrial zones).

We use the losers to identify what would have happened to the
roductivity of incumbent firms in the “winner” zones in the ab-
ence of the industrial park policy. Specifically, we assume that in-
umbent firms’ TFP would have treated identically in the absence
f the industrial park in “winner” and “loser” zones. To support the
alidity of this research design, we will test the similarity of the
re-trends in TFP and the balancing of many ex-ante observable
haracteristics of “winner” and “loser” geographic areas. Among
he 40 new parks during 1998–2007, 30 are the “winners” in the
arly-defined industrial zones. We match each of them with the
eographically closest “loser” to assure that they are as similar as
ossible.
We regard the “loser” zone as a runner-up, and define the
rea outside the “loser” zone but two kilometers from the zone’s
oundary as its “hypothetical” impact area. We define the dummy
inner which equals to one for the park and its impact area, and
quals to zero for the “loser” zone and its “hypothetical” impact
rea. In Eq. (3) , instead of using plants in the “Outside ” area as the
ontrol group, we estimate a park’s (or a park’s impact area’s) TFP
r wage premium using its corresponding “loser” zone (or its im-
act area) as the control area. We also include winner-loser pair
xed effects, so that the coefficient α3 measures the within-pair
FP or wage premiums of the park and its impact area.

.2.3. Cross-sectional comparisons for measuring park treatment
ffects
For the parks built before 1998, we do not observe a pre-period
n our data sets. We still seek to compare the economic impact of
hese parks on nearby economic activity. Since we cannot intro-
uce a DID specification here, we instead estimate a type of cross-
ectional model ( Eq. (4) ) where the control group are geographic
reas in the same year, in the same city (and the same district
ithin a city) that are equi-distant to the city center and other
ey locations (highway, railway station, airport and major univer-
ity, which are included in X it ).
it = αC 0 + αC
1 · T reat men t i j + βC ×X it + cit y F Es
+ dist rict −year t rend + indust ry −year F Es + μi + ε it (4)
By estimating Eq. (4) , we rely on the classic urban monocentric
ity model. This model assumes that within a city at a point in
ime that any two locations that are equi-distant to the city cen-
er (and other key locations) are perfect substitutes. The payoff for
s of adopting this framework is that it allows us to construct a
ross-sectional control group for geographic areas treated with an
ndustrial park. The treatment group contains either the plants in
arks, or the plants in parks’ impact areas.
Similarly, when testing the consumption spillovers of industrial
arks (home price, home sales, and the number of new restaurant,
ntertainment facility and retail shop openings in a vicinity of an
ndustrial park), we also estimate the cross-sectional model ( Eq.
4) ) because these consumption data sets exist for the years after
006.
Most of the land within industrial parks is zoned as industrial
and, but a small number of land parcels are zoned for residential
nd commercial uses. So we will see some apartments and retail
hops within parks but high density of them just outside the park
oundary. Since no favorable policy exists for residential and retail
ectors within the park boundary, in later empirical work testing
onsumption spillovers we will combine a park and its impact area
ogether (we call this whole area as ParkVicinity ) and regard it as
he treatment area.

This cross-sectional model is also used to identify the scope
f the impact area in which spillovers exist. For each type of the
pillovers, we will assume the same spatial scope for the impact
reas of all new parks. We define a set of dummies, OutRing (0, x ),
utRing ( x , 2 x ), OutRing (2 x , 3 x ),…, OutRing (( n-1 ) x, nx ), to denote a
et of x -kilometer-width rings ( x = 1 or 2 km) in this impact area,
rom inside to outside. Assume that the impact area ends at n x
ilometer from the park’s boundary. To reveal this width of the
mpact area, we augment Eq. (4) by including the set of OutRing
ummies ( Eq. (5) ). Y can be one of the productivity or consump-
ion spillovers variables. We expect to observe sharp discontinuity
t the boundary of the first several rings. As we move outward, the
oundary discontinuity vanishes at the boundary of a specific ring
namely n x from the park’s boundary, so the coefficient of the Out-
ing dummy changes to be statistically insignificant from n ). Then
e regard n x as the total width of the impact area.

Table A2 and A3 in Appendix C show how we identify the aver-
ge park’s impact area in terms of TFP and consumption spillover
ndicators. Figure A1 and A2 intuitively show the boundaries of the
mpact areas of production and consumption spillovers. The results
how that the scope of the impact area for TFP spillovers is on av-
rage 2 km from a park’s boundary, while that for housing and
etail market spillovers is on average 8 and 5 km from the park’s
oundary, respectively.
. Main results
.1. The mayor’s park site selection decision
To understand the mayor’s site selection problem, we estimate
discrete choice model where the dependent variable equals one
f city j ’s zone k has at least one park in 2006. The exogenous vari-
bles in this site selection model will be used as instrument vari-
bles in later regressions when we estimate parks’ productivity and
onsumption spillovers. We estimate Eq. (6) below:

= αP 0 +
∑
l
αP 1 l · Z lk +
∑
h
αP 2 h · X hk + city F Es + ε kt (6)
The X vector includes location attributes of zone k , such as its
istance to the city center, highways, the railway station, the air-
ort and the closest university. We include city fixed effects. The Z
ector contains two plausibly exogenous variables. The first is the
ensity of rural villages by zone ( Village_Density ). The city leader
as to negotiate with the heads of the villages occupying the land
bout the compensation fee, so that he can relocate the farm-
rs in those villages to other places, and thus vacant the land for
park. To reduce the compensation paid to those rural villages,
he city leader tends to choose a place with a small number of
illages. The second Z variable is a dummy indicating whether a
one locates in the downstream of its nearest river within the city
oundary ( Downstream ) . 17 City mayors know that some manufac-
uring firms in industrial parks will produce pollution. One strategy
mayor may pursue is to locate the park near the downstream
f the river(s) within the geographic boundary of his jurisdiction.
17 For a river flowing through a city, we identify its entrance point into and its
xit point out of the city. We measure a zone’s distance to the entrance point, and
lso its distance to the exit point. If the latter is shorter than the former, we set
Downstream = 1” for this zone. Otherwise, Downstream = 0.

n this way, he can keep the job opportunities and tax revenue
his park generates, without suffering from the water pollution this
ark causes ( Cai et al., 2016; Sigman, 2002 ).
Column (1) in Table 2 reports the estimates from a probit model
f Eq. (6) . The dependent variable equals one if zone k is the home
or at least one industrial park by the end of 2006. We can observe
hat industrial parks are more likely to be located further from the
ity center and closer to railway stations. Zones with a lower vil-
age density, or located in river downstream areas are more likely
o have industrial parks by 2006. In later sections we will use the
vector ( Village_Density and Downstream ) from Table 2 as our in-
truments. We will present IV estimates of the productivity and
onsumption spillovers, as a robust check for the OLS estimates.
In Column (2) of this table, we report results from a condi-
ional logit regression model where we study the correlates of the
pening of industrial parks established in our study period (year
998–2006). We match each park with all the zones in that city,
o the observation here is a zone-park pair. We estimate a condi-
ional logit model to examine whether a newly-established park j
atches with zone k . The results are similar.

Note: This table reports results from estimating Eq. (4) . All 110 parks are
included when constructing the treatment groups ( Park and ImpactArea ). In
all columns the omitted category is the observations in the “Outside ” area
(located more than two kilometers from the park’s boundary).
In columns (1) and (2), observations are individual plants that have a small
zone identifier. Other controls include the real travel distance to CBD (in
log),the “global” impact of other parks, natural log of the plant’s size and
age, natural log of its distances to the closest railway station and airport,
district-time trend, industry-year fixed effects, and plant fixed effects. Stan-
dard errors are reported in parentheses and they are clustered at the small
zone level. In column (3), the unit of analysis is a zone/year. The num-
ber of manufacturing jobs per square kilometer by zone is regressed on
the real travel distance to CBD (in log), treatment group dummies, park
opening dummies ( After ), four location variables (natural log of zone’s dis-
tance to the closest highway, railway station, airport and university), dis-
trict fixed effects and year fixed effects. The Vuong statistic favors the ZIP
(zero-inflated Poisson) model. In the first stage of the ZIP model (inflate
regression), we regress employment density on location variables includ-
ing distance to the CBD as well as its quadratic term and cubic term, the
natural log of distances to the closest highway, railway station, airport and
university, zone size, the city quadrant this zone locates in (north, south,
east, or, west), district fixed effects and year fixed effects. Incidence-rate
ratios are reported, transformed standard errors are reported in parenthe-
ses, which are clustered at district level.

18 We have also studied the probability that incumbent firms in the impact ar-
eas remain as producers rather than exiting the industry. The estimation results are
available upon request. All else equal, we find that the probability that an incum-
bent plant dies is lower when this plant is located in the impact area and the park
has opened.
110 parks. In columns (1) and (2), the observation is a plant, and
the control group are manufacturing plants in the same city and
year located more than two kilometers from a park (in the Outside
area). We include city fixed effects, district-time trend, industry-
year fixed effects, and plant fixed effects. In column (3), the unit
of analysis is zone/year, and we include district fixed effects and
year fixed effects. As shown in Table 3 , plants located inside the
parks have on average 13% higher TFP, 8.2% higher wages. In col-
umn (3), the coefficient on “park” indicates that the employment
density in treated zones is 71% higher than in control zones. This
table presents new findings on spillover effects. Recall that the
“ImpactArea ” is the area outside of the park but within two kilo-
meters from the park boundary. We estimate the spillover effect
o be 8% on TFP, 3% on wages and 41% on employment in this im-
act area, compared to the control group (the Outside area).
If industrial parks generate positive spillovers in their impact
reas, we should also observe that, all else equal, firms closer to
arks will have a higher probability to survive. We test this by es-
imating a probit model (see Appendix D). We do find that plants
loser to industrial parks have a lower probability to exit. This is
nother piece of evidence supporting the industrial parks’ produc-
ion spillovers.
.2.2. Difference in difference estimators of the average treatment
ffect
For forty of the parks that were established after 1997, we can
stimate Eq. (1) with the DID specification. Estimates of the aver-
ge treatment effect reveals whether the treated area was more or
ess productive after the park was opened there.
In Table 4 , we report six regression estimates of Eq. (1) in
hich the dependent variable is a plant’s TFP in a given year. In
ll columns the control group are plants located more than two
ilometers away from the park boundary (in the Outside area). In
olumns (1)–(3), we focus on estimating TFP premiums within the
ark itself by dropping all plants in the “ImpactArea ” . As shown
n column (1), these new parks were built in the originally less
roductive areas of the city. The average TFP for plants located
n areas where parks would be built in the future but have not
een built yet is 26% lower than those in the control plants. The
lants (including incumbent plants and new entrants) in the parks
re 25.7% more productive after the introduction of the park. In
olumn (2), we use two Z variables ( Village_Density and Down-
tream ) to instrument for Park . The TFP premium in this IV re-
ression is significantly positive and is of a similar size (a little
arger) as that in column (1). The first-stage estimates indicate
he validity of our IV specification (see the joint-F test in Table
. In addition, the Sargan test of over identification is rejected,
nd the weak instrument test is passed). In column (3), we in-
lude plant fixed effects, and find that the incumbent plants in
he park experience a 22% increase in productivity when the parks
pen. These results indicate that these less productive firms at
he baseline enjoyed a productivity boost from the opening of the
ark.
We are more interested in the estimates of TFP spillovers. In
olumns (4)–(6) of Table 4 , the control group includes the plants
ocated more than two kilometers away from the park. In this case,
e drop all plants in the park as we focus on estimating spillover
ffects on the “impact area” . We find that the impact areas ex-
erience a boost in TFP when the park opens. The ImpactArea ∗After
oefficient equals roughly 12.7%, so the TFP spillover effect is about
alf of the TFP premium within the park (25.7% in column (1)). 18
he IV regression in column (5) yields a similar coefficient esti-
ate. When we include plant fixed effects this coefficient becomes
little smaller (10.9%).
Other explanatory variables in Table 4 are found to have intu-
tive signs. State owned enterprises and firms that attract less FDI
re less productive. Firms closer to the city center are more pro-
uctive. Two surprising findings are that larger plants and younger
lants are more productive.
In Table 5 , we switch the dependent variable from TFP to wages
nd the local employment density. In Panel A, the wages in parks
re 12.7% higher after the introduction of the park. When plant
xed effects are considered and we track those incumbent plants

Note: This table reports results from estimating Eq. (1) . Plants with small zone identifier are included. In all columns the omitted category is the plants in the “Outside ” area
(located more than two kilometers from the park’s boundary).
Other controls include natural log of the real travel distance to CBD, the “global” impact of other parks, natural log of the plant’s size and age, dummies of whether the plant
is a SOE plant or a FDI one, natural log of its distances to the closest highway, railway station, airport and university, city fixed effects, district-time trend, and industry-year
fixed effects. The time-invariant variables (natural log of the real travel distance to CBD, whether the plant is a SOE plant or a FDI one, and natural log of its distances to
the closest highway and university) are omitted when including plant fixed effects in columns (3) and (6).
Columns (2) and (5) show 2SLS regression results of Eq. (3) . In column ( 2 ), the two exogenous variables in Table 2 ( Village_Density and Downstream ) are used as IVs for PARK
(and their interactions with AFTER as IVs for PARK • AFTER ). In column (5), we construct the IVs for ImpactArea in the following way: for each plant, we calculate the average
of this IV’s values in zones which are located within 2 kms from the plant, and use these average variables as the IVs for ImpactArea . The Sargan test of over identification
is rejected, and the weak instrument test is passed (minimum eigenvalue statistic far exceed the 5% Wald test critical values of 11.04). These tests, together with the joint F
test in Table 2 , all indicate the validity of our IV specification.
Plant fixed effects are included in columns (3) and (6), therefore the time-invariant variables (natural log of the real travel distance to CBD, whether the plant is a SOE plant
or a FDI one, and natural log of its distances to the closest highway and university) are omitted.

hose wages are observed before and after the park, this wage

pillovers in the impact area are about 6%–6.6%. The IV results
re quite robust. Similar to TFP estimates, the wage spillovers in
he impact area are also about half of the wage premiums in the
ark. Panel B reports employment density regression results. Zones
ithin the park and the impact area have experienced 80% and
0% increases in manufacturing employment density after the park
s established, respectively.
It is interesting to compare the sizes of TFP and wage spillovers
n the park’s impact area. Firms face a trade-off between the in-
reasing agglomeration economies and the increasing input costs.
he positive agglomeration economies increase the productivity of
earby incumbent plants, as indicated by the 12% increase in TFP
n the impact area. This leads to entry or relocation of firms who
re interested in gaining access to the spillovers to the vicinity
f the park. The expansion of existing firms and the subsequent
ew entry lead to competition for inputs, so incumbent firms face

In panel A, observations are individual plants that with small zone identifier. Specifications of columns (1) to (6) are same as those reported in Table 2 .
Other controls include the natural log of the real travel distance to CBD, the “global” impact of other parks, natural log of the plant’s size and age, dummies of whether
the plant is a SOE plant or a FDI one, natural log of its distances to the closest highway, railway station, airport and university, city fixed effects, district-time trend, and
industry-year fixed effects. The time-invariant variables (natural log of the real travel distance to CBD, whether the plant is a SOE plant or a FDI one, and natural log of its
distances to the closest highway and university) are omitted when including plant fixed effects in columns (3) and (6). Standard errors are reported in parentheses. They
are clustered at small zone level. In panel B, the unit of analysis is a zone/year. The number of manufacturing jobs per square kilometer by zone is regressed on natural log
of the real travel distance to CBD, treatment group dummies ( Park in columns (7) and (8), ImpactArea in columns (9) and (10)), park opening dummies ( After ), four location
variables (natural log of zone’s distance to the closest highway, railway station, airport and university), district fixed effects and year fixed effects.
In columns (2) and (8), the two exogenous variables in Table 2 ( Village_Density and Downstream ) are used as IVs for PARK (and their interactions with AFTER as IVs for
PARK • AFTER ). In columns (5) and (10), we construct the IVs for ImpactArea in the following way: for each zone, we calculate the average of this IV’s values in zones which
are located within 2 km of the zone, and use these average variables as the IVs for ImpactArea .
Our IV specifications have passed the over identification restriction and weak instrument tests. The Vuong statistics all favor the ZIP (zero-inflated Poisson) model. In the
first stage of the ZIP models in column (7) to (10), inflate regression, we regress employments density on some location variables (distance to CBD as well as its quadratic
term and cubic term, natural log of distances to the closest highway, railway station, airport and university), zone size, the city quadrant this zone locates in (north, south,
east, or, west), district fixed effects and year fixed effects.
Incidence-rate ratios are reported, transformed standard errors are reported in parentheses, which are clustered at district level.

higher prices for labor and land. The magnitudes of the changes in
the labor or land prices depend on their supply elasticities. When
the agglomeration economies generated by the industrial park are
strong enough, the magnitude of the spillovers exceeds the in-
creases in production cost. In the short run, profits will be positive
for incumbent firms that reside close to the parks. These positive
profits will disappear over time as the prices of local factors are
bid up.
Tables 4 and 5 show that in the impact area TFP and wages
increase by 12% and 6%, respectively. In our sample, labor ac-
counts for roughly 24% of total costs, so the estimated 6% increase
in wages implies that manufacturers’ costs increase by approxi-
mately 1.44%. The increased production costs due to higher wages
are therefore 12% of the gain in TFP. This suggests that incumbent
plants in the impact area gain a short run increase in their profits.
To mitigate the concern that the park’s productivity premium
comes from the selection effect—the industrial parks are selected
to be put in those locations with higher production potential, we
conduct a pre-trend test . We decompose After jt in Eq. (1) into var-
ious year dummies both before and after the industrial park’s in-
troduction, and set the previous year before the establishment of
the park as the benchmark year. Table 6 reports the estimated re-
ults. The coefficients of the event time indicators in columns (1)
nd (2) respectively reflect yearly mean TFP of firms within indus-
rial parks and in the outside areas relative to the previous year of
he park’s introduction. Column (3) reports the difference between
olumns (1) and (2). The control variables in Table 6 are the same
s those in column (3) in Table 4 . The estimated coefficients of
re-event time indicators in column (3) are all insignificant, which
ndicates that the trends in firm’s TFP patterns in industrial parks
nd control areas were similar prior to the establishment of in-
ustrial parks. The gap between the treatment and control areas
tarted to emerge after the park opens.
Fig. 4 A graphs the estimated coefficients of this pre-trend test.
he top panel separately plots the mean TFP of firms within parks
nd in the outside areas (columns (1) and (2) of Table 6 ). The bot-
om panel plots the differences in the estimated treatment and
ontrol groups’ coefficients (column (3) of Table 6 ). The same pre-
rend test is also applied to wage and employment density, and the
esults are shown in Fig. 4 B and Fig. 4 C, which also show that the
reas selected as industrial parks did not perform better ex ante
ompared to the areas far away.
One possible concern is that the new economic activity do not
epresent “net growth” but are shifted from other places (“spatial

ransfer” ), and thus represent a city level “zero sum game” . Figs.
A–C can partially mitigate this concern. As illustrated in Fig. 4 A
nd B, the plant-level TFP and wage in the outside area (the rest
f the city which is not affected by parks) do not show a declining
rend after the parks are established, while both of them within
arks do experience a significant increase. In Fig. 4 C, the employ-
ent density in the outside area has a slight decline after the in-
roduction of parks, indicating the spatial shift of some firms from
ther places towards the designated parks. Nevertheless, the TFP
nd wage results in Fig. 4 A and B do confirm our parks generate
ositive premiums without causing the productivity losses in the
est of the city.
If we think about the park itself and its impact area, the impact
rea receives spillovers from the park, but at the same time there
ay be a “gravitational pull” such that activity in the impact area
oves into the park or the park’s firms produce the output more
roductively and drive out some of the impact area’s incumbent
rms. What we observe is a “net impact”, and it will be hard to
eparate these two effects. Our em pirical results show that this net
mpact is positive.
.2.3. Estimating the park’s impact based on matched winner and
oser areas
In this section, we mimic the Greenstone et al. (2010) strategy
o compare outcome dynamics for geographic areas treated with
park relative to geographic areas that just missed based on our
eading of the Chinese CCP old urban planning documents. To be-
in to study this issue, we first present the productivity dynamics
f the average plant in the winner (industrial park) versus loser
early-defined industrial zones which did not receive a park) areas
or each year before and after the park was opened. In Table 7 ,
olumns (1) and (2) report estimated parameters and their stan-
ard errors from a version of Eq. (3). Specifically, the natural log
f TFP is regressed on the “global” impact of other parks, natural
og of the plant’s size and age, and natural log of its distances to
he closest railway station and airport. We include city fixed ef-
ects, district-time trend, industry-year fixed effects, plant fixed ef-
ects, winner-loser pair fixed effects, and the event time indicators.
he reported coefficients on the event time indicators reflect yearly
ean TFP in winner areas (column (1)) and loser areas (column
2)), relative to the year before the park was established. Column

3) reports the yearly difference between estimated mean TFP in
inner and loser areas.
Fig. 5 A graphs the estimated coefficients of this pre-trend test
rom Table 7 . The top panel separately plots mean TFP in winner
nd loser areas (columns (1) and (2) of Table 7 ). The bottom panel
lots the differences in the estimated winner and loser coefficients
column (3) of Table 7 ). 19 The same process is also applied to wage
nd employment density, and the results of this pre-trend test are
hown in Fig. 5 B and C.
As shown in Table 7 and Fig. 5 A–C, we cannot reject the hy-
othesis that there is no pre-trend differential for the treatment
roup and the control group before the park is opened for all three
roductivity measures. After the park opens, the gap between the
inners and losers appears and a linear relationship is observed. It
s notable that the loser areas also experience TFP growth but at a
esser rate than the winner areas.
In Table 8 , we report estimates of Eq. (3) with the DID specifi-
ation. The control group is the loser area (runner-up) and its “hy-
othetical” impact area. The sample size is smaller now relative to
he results reported in Table 4 because now we focus on a subset
f the treated plants and on a subset of the control plants.
In Table 8 ’s Panel A’s left column, we estimate a roughly 20%
reatment effect of being in a new park on plant TFP. These re-
ults are robust to including plant fixed effects (see column 2).
ased on the results reported in Panel A’s right column we find
hat plants located in the impact area (but outside) of new parks
xperience a 10% increase in TFP. Again, this is evidence of the spa-
ial spillover effect, and the size is about half of the park’s own

er” and “loser” geographic areas. The results are available upon request.

FP premium. These estimates are relatively smaller than those in
able 4 (with baseline DID specification), so our matched DID spec-
fication helps to mitigate the problem of omitted variables (they
ffect park’s location choice and the TFP premiums/spillovers with
he same direction). We find similar positive effects for wage gains
t 7% for new park plants and at 4.4% for impact area plants (see
anel B) and again large impacts on treated zone overall employ-
ent growth (see Panel C).
.3. Consumption spillovers: housing sales, prices and new retail
penings
We now turn to estimating how new parks affect local real es-
ate construction and pricing and the openings of new retail stores.
ur consumption data sets start from 2006, after the establish-
ent of all the 110 parks in our sample. To study this we estimate
q. (4) .
Table 9 reports four count models (new home sales, new
estaurant/ entertainment/ retail openings) and one hedonic pric-
ng model (new home prices). The unit of analysis is by grid cell by
ear for the count models, and it is by residential complex (with
xact address) by year for the hedonic pricing model. The spa-
ial boundary of the impact area is 8 km from the park’s boundary
or new home sales, and 5 km from the park’s boundary for new
estaurant openings, entertainment facilities and retail shops (see
able A3). Figure A2 graphs the distribution of these spillover ef-
ects at various distances (with confidence intervals). According to
survey conducted by Baidu.com , the average one-way commut-
ng distance in these eight cities varies between 13 km to 19 km

n 2015. 20 An industrial park can be regarded as an edge city or a
ubcenter, which attracts nearby workers, so the commuting dis-
ance should be shorter than the city average. The 8-km radius for
he housing market spillovers seems to be a reasonable size.
All else equal, home prices are roughly 12% higher in the vicin-
ty of an industrial park (the park and its impact area). The counts
f new home sales, new restaurants, entertainment facilities and
etail shops also rise sharply in the vicinity of the park- 43%, 51%,
9% and 50% more than a comparable place. In results available on
equest, we have re-estimated these results using an IV specifica-
ion using the variables listed at the bottom of Table 2 . We find
hat our IV results are quite similar. These results are available on
equest.
Based on the results reported above, we calculate the rough
enefits the local government could gain by building an industrial
ark. The land value premium in this average park’s impact area
s about 23 billion RMB. Given Chinese land market rules, this is a
netime payment but it is quite large as that amount equals 33%
f the average city’s annual fiscal revenue flow in the year 2007.
he land where the park is placed could have been auctioned off
s residential and commercial real estate. Using standard hedonic
ricing methods, we estimate the opportunity cost of the average
ark’s land to be 4.1 billion RMB. 21 This opportunity cost under-

ark’s vicinity is much larger. Here we estimate the residential land sale revenue
o give an example. Our estimates (column ( 2 ) in Table 9 ) show that the av-
rage industrial park increases home prices in its vicinity by 11.7%. We assume
hat land prices increase by the same rate. We obtain the land sale auction price
ata for the year 2007, and use the spatial gradient estimated from the housing
rice hedonic regression to predict the price of land across the city. We acknowl-
dge that we do not take general equilibrium effect into account here and we
se post-improvement prices (after the public project investment) instead of pre-
mprovement prices when conducting the estimation. On the cost side, to attract

stimates the total cost of the park because there are other often
idden costs. It is difficult to obtain the cost parameters of infras-
ructure investment, land, tax and utility subsidies for building an
ndustrial park because such cost information is always regarded as
secret” and is hidden by local governments. Our interview with an
fficer at NDRC (National Development and Reform Commission of
hina) gives us a rough estimate of 2.5 billion of such costs for an
verage park in those cities. Combining the above costs together,
hey only accounts for 28.7% of the land value premium in its im-
act area. Therefore, even without counting the long term annual
ows of tax revenue from firms, the huge net benefit from land
ales (land value premium in the impact area minus the opportu-
ity land cost within the park) already creates incentives for may-
rs to build industrial parks. But of course such huge land sale
evenue depends on that the park itself is successful in terms of
enerating productivity gains. Since China’s mayors face term lim-
ts with the average term length running to around four years, the
p-front land revenue incentives may even be stronger than col-
ecting a long term annual flow of tax revenue from manufacturing
rms.
. Measuring park treatment effect heterogeneity
In this section, we first present estimates documenting the dis-
ribution of park heterogeneous treatment effects and then we use
deas from the economic agglomeration literature to test various
ypotheses. In Fig. 6 , we graph the treatment effects for 40 parks
roductive firms, local governments always sell the industrial land within the park
o them at very low subsidized prices, and in some cases even at a price of zero.
e estimate the opportunity cost of this favorable land subsidy by calculating the
arket value of the land within the park if it could have been developed into resi-
ential uses (assuming zero prices for industrial uses). This subsidy is valued at 4.1
illion RMB for the average park.

q. (1) (with plant fixed effects).
Fig. 6 highlights the fact that some of the parks have a neg-
tive but statistically insignificant effect on plant productivity. If
e count numbers, 75% of the new parks built during 1998–2007
n the eight cities generate positive TFP premiums within park
oundary; while 25% of those parks turns out to have negative TFP
remiums. Regarding TFP spillovers to nearby incumbent firms,
0% of the parks have positive spillovers; and 30% have negative
pillovers (most of the negative coefficients are insignificant).
In Section 2.3 we already define four dimensions measuring
ark heterogeneity—the cohort and age of a park; its administra-
ive level; the extent to which this park “fits” with the local incum-
went industries; and its own composition of plants and industries.
ow we examine the heterogeneous productivity and consumption
pillovers along those dimensions.
.1. Heterogeneous productivity spillovers as a function of park
ttributes and Marshallian factors
In panel A of Table 10 , we allow the impacts of an industrial
ark to vary by a park’s age. We find that older parks do have
arger spillovers. As time passes, the spillovers for both old and
ew parks become larger. We interpret this as evidence of a “mul-
iplier” effect. In Panel B, we find that the state-level parks gener-
te larger TFP spillovers compared with provincial-level parks, but
hey have little difference in wage spillovers. In Panel C of Table 10 ,

shallian factors correlate with spillover effects. We find that knowl-
edge spillovers have the largest effect on TFP and wages. We also
find some evidence supporting the roles of input and output link-
ages, and labor pooling in local economic growth. Finally in Panel
D, we describe the parks based on a variety of dimensions and
find that parks featuring a higher human capital share, a higher
foreign direct investment, and a higher co-agglomeration effects
within the park have a higher spillover effect. Perhaps surprisingly,
we do not find that parks with higher share of state owned enter-
prises have a smaller TFP effect. However, we find that the wage
impacts on the impact area are smaller for parks with a larger SOE
share. The magnitudes of these results are large. A ten percentage
point increase in the share of park workers who are college grad-
uates is associated with a 26% increase in the TFP spillover in the
impact area.
5.2. Heterogeneous consumption spillovers as a function of the park’s
composition of new firms
Our final piece of the empirical work examines how the con-
sumer city spillovers are affected by the park’s administrative level
and its attributes.
These results are qualitatively very similar to the results re-
ported for the producer spillovers in Table 10 ’s Panel C and Panel
D. All else equal, for state-level parks and parks featuring more hu-
man capital, greater co-agglomeration, more FDI and fewer SOEs,
we find a larger spillover impact on nearby housing construction,
home prices and new retail openings. These results support our
claim of the heterogeneous impacts of parks and the key role
that the composition of these parks plays. The finding that the
co-agglomeration index has a positive spillover effect in both the
TFP regressions and in the consumer city regressions supports the
claim that this is new synergistic activity rather than simply be-
ing reshuffling of economic activity that would have taken place
somewhere in the same city in the absence of the park’s creation.
As shown in Table 11 , parks featuring a larger SOE share have a
smaller impact on the local housing market and on the creation of
new retail outlet and restaurants.
.
. Conclusion
Our paper provides strong support for Marshallian theories of
ocalized production and consumption agglomeration in a lead-
ng developing country. Using the opening of 110 industrial parks
cross eight major Chinese cities, we quantify the spillover effects
n productivity, manufacturing employment, incumbent firm sur-
ival, real estate construction, real estate pricing, and retail store
penings for economic activity close to these new suburban cen-
ers of productivity. Consistent with Marshall’s core hypotheses, we
nd that proximity to the parks facilitates trade and growth be-
ause such co-agglomeration reduces the costs of moving goods,
eople, and ideas.
We have also documented that the parks differ with respect
o their productive spillover effects. A recent literature in macroe-
onomics measures the productivity wedges across Chinese firms
Hsieh and Klenow, 2009 ). This research argues that government
nduced distortions act like a subsidy for unproductive firms. For
xample, state owned enterprises receive special treatment in re-
eiving cheaper land and capital access. Our results indicate that
overnment policies that encourage the creation of high human
apital industrial parks are more likely to facilitate productivity
rowth.
Unlike previous evaluations of government subsidizes for place-
ased programs, we have explicitly measured impacts for both the
roduction and consumption sides of the economy. The new park
reates a spatially concentrated increase in local market potential
s well paid workers seek nearby housing and retail opportunities.
iven that Chinese urbanites spent a great deal of time commuting
o work, household quality of life is improved by having suburban
mployment options where they can live and shop with access to
uch shorter commutes. Unlike in the classic monocentric Chinese
ity, this means that the new parks lead to sharp improvements in
orker quality of life and this should attract talented workers to
eek these jobs ( Duranton and Turner, 2011; Monte et al., 2015 ).
Our results clearly show that not all industrial parks are “suc-
essful”, even in our sample of 110 parks in the first-tier cities and

Note: This table reports results from fitting versions of Eq. (1) . We use the baseline DID specification to examine the heterogeneous treatment effect in a park’s impact
area.
In panel A, we add the interaction terms between Park ∗After and the indicated park cohort dummies and age group dummies. In panel B we add interaction terms between
Park ∗After and the indicated variables of how a park “fits” with the local incumbent industries measured by continuous economic distances between firms within the park
and the incumbent firms outside but nearby the park. These industry linkage measures are defined and described in Table 1 , and Appendix B provides how we construct
those variables. In panel B we add interaction terms between Park ∗After and a dummy indicating whether a park is a state-level one. In panel D we add interaction terms
between Park ∗After and the indicated measures of a park’s own “economic power”. These park feature measurements are defined and described in Table 1 .
Other controls include DID dummies, the “global” impact of other parks, natural log of the plant’s size and age, natural log of its distances to the closest railway station
and airport, city fixed effects, district-time trend, industry-year fixed effects, and plant fixed effects.

Note: Column (1) reports results from fitting version of Eq. (1) , column (2)-(6) report results from fitting versions of Eq. (4) . We employ zero-inflated Poisson model for
all columns except of column (3) (where we use OLS). In panel A we add interaction terms between Park ∗After/ImpactArea and a dummy indicating whether a park is a
state-level one. In Panel B we add interaction terms between Park ∗After/ImpactArea and the indicated measures of a park’s own “economic power”. These park feature
measurements are defined and described in Table 1 . Other specifications of column (1) are the same as those reported in column (9) of Table 5 . The other specifications
reported in columns (2)-(6) are same as those reported in Table 8 . ∗ denotes p < 0.10, ∗∗ denotes p < 0.05, ∗∗∗ denotes p < 0.01.

relatively large cities. 22 The geographic spillover effect of parks is
an increasing function of the park’s overall human capital level,
the FDI share, the SOE share and its “synergy” with nearby in-
cumbent firms. Nevertheless, on average we do find positive pro-
duction and consumption spillovers. Other studies on China’s in-
dustrial parks also confirm such positive impacts on local eco-
nomic growth. Therefore it is interesting to understand why this
place-based policy did not work well in many developed coun-
tries ( Busso et al., 2013; Glaeser and Gottlieb, 2008; Papke, 1994 ),
but has an optimistic outcome in China. We propose two possible
(and speculative) explanations: First, in developed countries, place-
based policies often target those lagged-behind regions. China’s in-
dustrial park policy incorporates both efficiency and equity moti-
vations together with the additional target of experimenting with
market reforms. On the efficiency side, industrial parks pursue the
reduction of pre-existing distortions in the old central planning
regime and the exploitation of agglomeration effects ( Alder et al.,
2016 ). Second, the active role of the government has been crucial
for China’s development because it supported a fast move towards
22 If data permits, this study should be expanded to less developed cities to see if
industry parks’ positive impacts diminish when this policy extends down the hier-
archy of cities. We tried our best but still cannot obtain this micro-level firm data
beyond these eight cities. Therefore, we view this to be a valuable future research
topic. In the conclusion, we mention the possibility that if we look at relatively
small cities and those cities in China’s middle and western regions, it is possible
that the probability of “unsuccessful” parks will rise.

ore modern and productive sectors which have positive exter-
alities on the whole economy ( Rodrik, 2006 ). In our case, the
managed hand” of Chinese city governments solve a land assem-
ly problem and a cross firm co-ordination problem allowing firms
o cluster together in a timely fashion, which is unimaginable in
ities featuring pre-existing durable structures. It may also not be
ossible in a US city where such projects would face more “Not In
y Back Yard” (NIMBY) opposition.
