摘要
大都市区是城市群的增长极核与辐射源,城市群又是其所在区域的增长中心,研究大都市区的溢出效应及城市群的集聚与扩散特征有助于为区域发展决策与战略研究提供经验借鉴。以长三角区域为例,在"六普"分县人口数据的基础上利用空间自相关等空间计量经济学方法,研究了长三角城市群的集聚与扩散以及大都市区的空间溢出效应。研究发现:人口等要素资源向长三角城市群集聚现象显著,但在城市群内部大都市区外围区县形成新的集聚空间,溢出效应明显;在影响经济空间格局的各因素中,除要素投入、政策、集聚经济等因素外,区位条件也有重要作用;是否邻接大都市区这一虚拟变量通过了检验,除了说明区位条件具有重要影响力以外,也进一步证实了大都市区的空间溢出效应。
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.
