经典引力模型难以刻画城市间的引力动态关系,高速公路流量大数据支撑将为城市经济学研究提供新的视角。引入高速公路起止点（OD）流量数据改进经典引力模型,并结合修正引力图谱可视化手段和空间自相关分析方法,探究湖北省县市尺度相互引力强度及空间关联结构。研究表明:（1）湖北省县市间联系强度地域分异明显,整体呈现明显的降次等级结构,武汉核心城市单极化发展,区域辐射作用较强,襄阳和宜昌副中心城市辐射作用不强。（2）湖北城市空间自相关呈现东高西低,中部均衡格局。高速公路交通流量与经济质量指数空间自相关的高—高集聚具有空间重叠现象,且省内大部分区域未出现明显的轴线或面域高—高...

The classical gravity model is difficult to describe the dynamic relationship of gravity between cities. The support of big data of expressway flow provides a new perspective for the research of urban economics. The paper improves the classical gravity model by using the expressway OD flow data, and combines with the modified gravity spectrum visualization method and spatial autocorrelation analysis, further explores the county unit scale mutual gravity strength and spatial structure in Hubei province. The results are shown as follows: (1) The cities are significantly geographical differentiat...
