中国城市地铁建设影响因素的空间差异分析——以京、津、沪、穗、深、宁六市为例

基于2007年中国已经开通地铁的六个城市的统计数据,选取影响城市内部地铁建设的因素,运用SPSS统计分析软件进行主成分分析,提取中国城市地铁建设的主要因子,在此基础上分析六个城市地铁建设影响因子的空间差异。结果表明:①中国城市地铁建设影响因素可归为三个主要因子,即城市建成区规模、政策支持和灵活、便捷的交通因子;城市现有的交通和二、三产业的发展状况;城市的经济实力和公路客运交通状况。②六个城市地铁建设的影响因素具有空间差异,按其驱动因子的个数,又可分为单因子驱动型,如北京、上海、广州和深圳,多因子驱动型,如天津和南京。

The Spatial Difference Analysis of Affecting Factors in Chinese Urban Subway Construction:A Case Study in Beijing,Tianjin,Shanghai,Guangzhou,Shenzhen,Nanjing

Based on the statistical data of the six cities which has operated the subway before 2008,this paper used principal component analysis of SPSS to extract the main factors in Chinese urban subway construction. Then it analyzed the spatial differerees of the affecting factors among them.
