城市群工业用地供给的经济效应与外溢边界比较研究OACHSSCD

Based on the industrial land supply and economic development data of the four major urban agglomerations in the Yangtze River Delta,Beijing-Tianjin-Hebei,Chengdu-Chongqing and Pearl River Delta from 2009 to 2021,this paper adopts static and dynamic spatial Durbin models and threshold adjustment step wise regression analysis to explore the influence mechanism of land supply on economic growth based on the collaborative background of urban agglomerations,and measures the spillover effect boundaries.The results show that:①The direct and spillover effects of industrial land supply on economic growth are different in urban agglomerations with different development levels.②For urban agglomerations with different development levels,the spatial spillover effect of industrial land supply economic performance changes with the increase of distance.③The industrial land spillover boundary of the Yangtze River Delta,Beijing-Tianjin-Hebei,Chengdu-Chongqing and Pearl River Delta urban agglomerations are 2.6 times,1.7 times,1.5 times and 3.0 times of the city radius,respectively.In the future,the allocation of industrial land in urban agglomerations should focus on promoting the coupling development of industrial land and industrial upgrading,implementing differentiated industrial land supply policies,and establishing an interactive mechanism between land supply indicators and the development of urban agglomerations.
