      基于物元模型的江苏省县域综合发展水平评价与区域差异研究

      A Study of Counties Comprehensive Development Levels and Regional Difference of Jiangsu Province Based on Matter Element Model

      摘要:
      以物元分析理论为基础,建立指标评价体系,通过物元模型对江苏省各县(市)的综合发展水平进行测度,从3个层次对影响县域综合发展水平的因素进行评价,并应用地理加权回归模型对影响综合发展水平及其空间分布的因素进行分析.结果表明:江苏省大部分县域处于低水平及中低发展水平,且空间分布不均衡.整体上呈现“东南-西北”走势,由苏南、苏中到苏北地区,县域综合发展评价等级呈现出递减的状况.4类子系统均对区域综合发展水平有较为明显的作用,对区域综合发展水乎空间分异的贡献度大体上呈现出南高北低的格局.
      Abstract:
      Based on the theory of matter-element analysis,this paper establishes the evaluation index system of comprehensive development level,measures the comprehensive development levels of counties in Jiangsu province,evaluates the influential factors from three levels.And using the Geographically Weighted Regression Model,this paper makes in-depth analysis of factors that influence the comprehensive development level and its spatial distribution.The results shows:the majority of counties stays at a low level and the spatial distribution is imbalance.On the whole,the spatial distribution shows" Southeast-Northwest" tendency,the comprehensive development level tends to decline along this direction.All of the four types of subsystems have impact on the regional variation of the comprehensive development levels of counties and presenting a decreasing pattern from south to north.
