Empirical Research on Spatial Spillover of Metropolitan and the Spatial Agglomeration and Dispersion in Yangtze River Delta Urban Agglomeration
利用空间计量方法分析长三角城市群中都市圈的空间溢出效应以及人口等要素的集聚与分散特征，发现要素持续向都市圈邻近县域流动，溢出效应显著。
The metropolitan areas are growth poles and radiation sources of the urban agglomerations,spatial spillover of which will improve the coordinated development of urban agglomerations,as well as the urban agglomeration regions.This paper analyzes the metropolitan areas’spatial spillover effects and the features of agglomeration and dispersion in urban agglomeration,using the method of the spatial econometrics,such as Moran index and spatial model,based on the census and statistics data.The study shows that population and other elements continue gathering to the Yangtze River Delta urban agglomeration,but most resources flow to the counties outside the metropolitan areas and neighbor to them,the spillover effect of which is significant.When we study the influencing factors,we find that agglomeration economies,location factors and policies’impacts are significant,especially for the dummy variable whether neighbor to metropolitan areas.
