Abstract:

According to the land supply results obtained from http://www.landchina.com/, this paper explored the spatio-temporal characteristics of state owned construction land supply of counties in China from 2010 to 2015 by using the spatial distribution of gravity-center, locational Gini index and hot spot analysis, and then analyzed the influencing factors of land supply of regions in different development phases based on panel data models. We found that land supply has experienced a process of increasing first and then decreasing, and spatial agglomeration degree, hot spot and sub-hotspot zones of land supply in counties were in general diffusion during the study period. Due to the implementation of "Western Development Strategy", "Aiding Xinjiang" and "Rise of Central China Plan", spatial distribution of gravity-center of land supply in counties moved evidently westward. The land supply was concentrated within the urban agglomerations. The administrative hierarchy of prefecture-level cities with counties was closely related to the land supply scale. In other words, the higher the administrative level of prefecture-level cities is, the larger the average land supply of counties is. There were differences in the total supply land size change and average land supply structure from region to region in different development stages. In general, the regions with high development stages need more construction land. Public finance expenditure, fixed asset investment, secondary industry growth rate, tertiary industry growth rate, growth rate of population size and per capita GDP have different effects on the land supply of regions in different stages. Among them, investment including public finance expenditure and fixed asset investment plays a critical role in promoting the land supply of regions in different development stages.
