山西省省内城市经济联系与城镇圈空间差异研究

Research on Economic Connections and Spatial Variations among Urban Clusters in Shanxi Province

摘要: 以山西省各地级市为单元，借助城市中心职能指数、可达性、引力模型对各地级市的经济联系进行测度，用Theil指数测度各城镇圈经济发展水平差异，由此分析省内城市之间的经济联系程度与空间差异。结果表明：(1) 各地市对外经济联系强度逐步增强，但各地市之间的经济发展存在较大差距，高级中心城市对低级城市的辐射带动作用不足，对外经济联系以城镇圈内为主，各城镇圈之间的经济联系程度不高。(2) 各城镇圈的整体空间差异逐步缩小，但各城镇圈之间的差异仍较大，城镇圈内部差异虽呈现降低趋势，但差异程度不尽相同，当前以晋东南和晋南城镇圈内部差异较小，中部城市群内部差异较大。建议重点落实“一群两区三圈”的区域发展格局，提升集聚效应和扩散效应，不断优化交通网络体系，强化区域间合作。

Abstract: Utilizing the urban center function index, accessibility, and gravity model, we measured the economic connections among various prefecture-level cities in Shanxi. Additionally, we employed the Theil index to assess the disparities in economic development levels among urban agglomerations. The findings reveal that: (1) The strength of external economic connections among cities is gradually increasing, yet significant disparities exist in economic development among cities, with higher-tier central cities fail to exert sufficient spillover effects on lower-tier cities, resulting in predominantly intra-circle economic linkages and weak inter-circle economic connectivity. (2) Overall spatial disparities among urban clusters are gradually narrowing, yet significant differences persist between clusters. Although the disparities within urban clusters are showing a decreasing trend, their extent varies. Southeastern and Southern Shanxi urban circles demonstrate smaller internal disparities, while more pronounced disparities exist within the central urban cluster. It is recommended to prioritize the implementation of the “one group, two districts, and three circles” regional development pattern, enhance agglomeration and diffusion effects, optimize the transportation network system, and strengthen regional cooperation.
