      中国三大城市群内部经济联系和等级结构的比较——基于综合引力模型的分析

      A Comparative Analysis on Economic Linkage and Hierarchical Structure of the Top Three Urban Agglomerations in China—Using a Synthesized Gravity Model

      摘要:
      文章对传统引力模型中城市质量以及城市之间距离的测算进行了适当的修正,基于修正后的引力模型,以长三角、京津冀和珠三角三大城市群为研究对象,测度了城市群内部城市间经济联系的紧密程度,并揭示了城市群内部城市的等级结构,进而对三个城市群进行了比较分析.结果表明:各城市群内部等级结构上均存在不同程度的断层,特别是次级城市发展不足;各城市群内部联系的紧密程度存在明显差异,珠三角城市群相对与长三角和京津冀城市群而言内部联系更为紧密;各城市群内部城市之间引力关系表现出明显的非均衡特征.
      Abstract:
      The paper modifies the traditional Gravity Model.In terms of the way it calculates the size of a city and the distance among cities,and is focused on the top three urban agglomerations of China,such as Yangtze River Delta's Urban Agglomeration,Beijing-Tianjin-Hebei Region's Urban Agglomeration and Pearl River Delta's Urban Agglomeration.Using the modified Gravity Model,the paper measures the intensity of the inter-city's economic linkages,and explores the hierarchical structure within each urban agglomeration,and then comparatively analyzed these three urban agglomerations.The results showed that to some extents,discontinuity in each urban agglomeration's hierarchical structure,particularly secondary level cities are under-developed;obvious differences can be observed with regard to the intensity of inter-city economic linkage within each urban agglomeration,linkages among cities within Pearl River Delta Urban Agglomeration are more intensive than those of the other two urban agglomerations;the intensity of inter-city linkages among cities in each urban agglomeration is unevenly distributed.
