中国三大城市群功能分工与人口集聚的空间效应

Spatial Effects of Functional Division and Population Agglomeration in China’s Three Major Urban Agglomerations

文章利用2010—2020年长三角、京津冀、珠三角三大城市群60个城市的面板数据,建立空间联立方程模型,实证分析长三角、京津冀、珠三角城市群功能分工与人口集聚空间效应的差异性与协同发展水平。结果表明:三大城市群均不存在明显的功能分工与人口集聚的正向空间交叉效应,未达到一体化发展水平;三大城市群的功能分工与人口集聚的空间溢出效应存在显著差异,整体而言,长三角城市群的协同发展水平高于珠三角城市群和京津冀城市群。

Based on the panel data of 60 cities in the Yangtze River Delta,Beijing-Tianjin-Hebei,and Pearl River Delta urban agglomerations from 2010 to 2020,this paper establishes a spatial simultaneous equation model to empirically analyze the differences and collaborative development levels of spatial effects of functional division and population agglomeration in the three urban agglomerations aforementioned.The results go as below:The three major urban agglomerations have not shown the positive spatial cross effect of functional division and population agglomeration,and have not reached the level of integrated development.There are significant differences in the spatial spillover effect of functional division and population agglomeration among the three urban agglomerations.Overall,the coordinated development level of the Yangtze River Delta urban agglomeration is higher than that of the Pearl River Delta and the Beijing-Tianjin-Hebei urban agglomerations.
