基于因子分析法的城市宜居水平实证研究

An Empirical Study on Urban Livable Level based on Factor Analysis

针对城市宜居性问题,文章选取淮海经济区内的8个城市(宿迁、连云港、宿州、商丘、济宁、枣庄、徐州、淮北)为研究对象,运用因子分析、回归分析等方法,建立基于主要指标的城市宜居水平评价模型,综合使用SPSS、EXCEL、MATLAB等软件,筛选出影响城市宜居水平的主要指标,构建城市宜居水平评价指标体系,对城市宜居水平进行科学排名,并分析显著影响城市宜居水平的因素,最后根据定量分析结果,针对性地给出提高徐州市宜居水平的政策建议。

Focusing on urban livability,we applied factor analysis,regression analysis and the analytic hierar-chy process to establish an evaluation model of urban livable level based on the main indicators. We used SPSS, EXMATLAB and other software to screen out the main indicators that affect the livability level of the the evaluation index system of urban livable level,as well as scientifically ranked urban livable level. We further assessedthe results of factor analysis and got the factors that significantly affect urban livable level. Finally,depending on the re-sults of quantitative analysis,we provided more scientific advice on how to improve the livable level of Xuzhou.
