How Does Land Allocation Affect Spatial Distribution of Urban Population
Against the background of increasingly scarce land resources,the mismatch between population and land resources has become frequent in China's urbanization process.This paper introduces government-led land allocation into the quantitative spatial model and analyzes the mechanism and effect of local government land allocation on the spatial distribution of urban population.The results of this paper show that local government land allocation bias has a significant guiding effect on population migration within cities.The government allocates more land to the city center,which can indeed guide the population to cluster towards the city center.Meanwhile,the effectiveness of the local government's"attracting people with land"policy is constrained by the productivity gap between the city center and its periphery.The smaller the productivity gap between the city center and the periphery,the stronger the role of local government land allocation in guiding the spatial flow of population within the city.When the productivity gap between the city center and the periphery is too large,the optimization effect of local government land allocation on the spatial distribution of urban population is greatly weakened or completely ineffective.This makes it difficult to shake the population agglomeration of areas with high productivity advantages.Due to insufficient demand in the land market,local governments'"attracting people with the land"policy often fails in population-outflowing cities and small and medium-sized cities.By contrast,it is more effective in population-inflow cities and large-scale cities.Further exploration shows that land allocation biased towards the outskirts of cities can guide the population to move towards the periphery,but it leads to problems such as reduced overall welfare of urban residents and urban sprawl.This paper has the following contributions.On the one hand,it deepens theoretical research on the relationship between local government land allocation bias and urban population spatial distribution.Based on the division of the center and periphery of a city,the block differences of government land quotas are introduced into the quantitative spatial model to analyze the theoretical logic and impact mechanism of the local government's"attracting people with land"strategy.Numerical simulations are used to identify the constraining effect of the productivity gap between the center and periphery on the strategy's effectiveness.On the other hand,it constructs a dataset by integrating LandScan population distribution data and land market transaction data and examines the role of local government land allocation bias in optimizing urban population spatial distribution.Meanwhile,the methods of structural estimation and counterfactual analysis are used to verify the constraining effect mentioned above.The conclusions provide references for local governments to optimize land allocation and effectively guide the spatial distribution of the urban population.
