江苏省县市城市化水平差异研究

On the Difference of Urbanization Level of Cities and Counties in Jiangsu Province

本文运用单一指标和复合指标两种类型,结合泰尔指数和因子分析法,对江苏省县市城市化水平差异的演变轨迹和现状特征进行分析,结果发现改革开放以来江苏省县市人口城市化水平总差异缩小的同时,苏南、苏中与苏北三大地区之间差异不断缩小,但对它总差异的贡献不断扩大,三大地区内部差异也不断缩小,且苏北地区内部县市城市化水平差异最大,在区域城市化水平总差异中一直占据主导地位。江苏省县市城市化水平综合差异主要表现为城市现代化、建成区规模和密度差异三个方面,在空间上主要表现为南北梯度差异和市区与县域之间的差异。
