Impact of Chinese Local Government-led Construction Land Supply Strategies on Urban Innovation and its Spatiotemporal Differences

This study constructs a theoretical framework to analyze the impact of local governmentled construction land supply(LGCLS)strategies on urban innovation.It uses data related to 265 cities in China from 2005 to 2019 for empirical analysis.Its conclusions are as follows.For development stage differences,the impact of LGCLS strategies on urban innovation exhibited an inverted U shape with economic growth.The inflection point occurred when the per capita GDP equaled approximately RMB23,101 in 2008.For regional diferences,the inflection point in eastern China is higher and earlier than that in central and western China;before the inflection point,the positive infuence was more obvious in the central and western regions,whereas after the inflection point,the negative influence was more obvious in the eastern region.For the eastern Yangtze River Delta urban agglomerations and the northwestern resource-based urban agglomerations with relatively high per capita GDP,the negative impact of LGCLS strategies on urban innovation occurred earlier and showed spatial agglomeration characteristics.

Examining the Impacts of Land Supply on Housing Price in Chinese Mega Cities: An Analysis of Prefecture-Level Cities in China from 2009 to 2016

Residential land supply is considered a powerful tool for intervening in the housing market in China. There has been continuous debate on the correlation between residential land supply and housing prices. Based on 35 Chinese prefecture-level cities’ panel data from 2009 to 2016, this study investigates the spatio-temporal characteristics of residential land supply and housing prices, and explores their relationship applying Generalized Moment Models(GMM). The results show that(1) there is an overall downward trend in residential land supply and a significant rise in housing prices in most Chinese mega cities from 2009 to 2016, and the extent varies in four economic-geographical regions;(2) the decrease in the quantity of residential land supply contributes to the rise in housing prices to some degree, but there is no significant correlation between the land supply structure and housing prices. With the integration of socio-economic factors, the quantitative results validate the previous theoretical models of the casual correlation between residential land supply and housing prices. It further depicts the constraint of insufficient residential land supply in Chinese mega cities and claims it to be a contributor of rising housing prices. The paper concludes with implications for housing strategies and future studies.

Interaction of Land Demand and Supply Effects in Intensive Land Use: a Simulation Study for Chengdu,China

Intensive land use( ILU) policies affect the demand and supply of land. These policies promote efficient land use, and demands for land must therefore be evaluated in terms of the level of land-use intensity. If the demand is considered excessive, ILU policies act like a "valve"to restrict the land supply. Drawing on data from Chengdu,China,where developable land is scarce,we construct a model using system dynamics( SD) to simulate two scenarios: ILU development and non-ILU development. The results show that when ILU leads to positive land-use efficiency,land supply will exceed demand,resulting in an appropriate level of real demand for the current population level and GDP. Thus,artificial demand( inflated by investors) is reduced. By contrast,when non-ILU leads to negative land-use efficiency,land demand will exceed supply. In this scenario,artificial demand is higher than real demand.

Government L and Regulations and Housing Supply Elasticity in Urban China

This paper studies the effects of government land regulations(GLR)on housing supply elasticity in urban China.We first extend the theoretical framework of Saiz(2010),then use land transaction microdata,satellite-generated data,and the construction of instrumental variables to analyze the marginal effect of GLR,and finally calculate the housing supply elasticity caused by GLR.Our analysis finds that GLR is an important reason for the overall inelasticity of housing supply in 272 Chinese cities,which reduces housing supply elasticity from 1.457(elastic)to 0.872(inelastic).Housing supply elasticity caused by GLR has declined the most in first-tier cities and the eastern regions.The marginal effect of land use regulation is greater than that of land allocation and supp!y regulations.The initial development level and natural geographic constraint of each city also matter in China's housing supply market.

The Environmental Consequences of Place-Based Policies in China:An Empirical Study Based on SO_(2)Emission Data

Previous studies of place-based policies in China have ignored their effect on pollution.Using event study and difference-in-differences methodologies,we investigated the consequences of place-based policies on sulfur dioxide(SO_(2))emissions.We first documented the increase in SO_(2)emissions and SO_(2)emission intensity in the inland region after 2003 at the provincial level.The firm-level data for the period between 1998 and 2010 also showed that the performance of enterprises in noneastern regions in reducing SO_(2)emissions had worsened relatively since 2003,and this effect was particularly strong in enterprises located in central and northeast China,where urban land supply experienced significant growth after 2003.We found that,compared with environmental regulation changes,inland region-biased economic policies after 2003 were more important in explaining the relative changes in SO_(2)emissions between coastal and inland regions.The policy implication is that the central government should address environmental consequences when designing place-based economic policies.
