摘要
以长三角25座中心城市为研究对象，利用熵值法从生活便宜度、环境优美度、社会发展度、经济富裕度四个层面构建综合指标体系作出评价，得出：第一，长三角25座城市宜居度可划分为I～Ⅳ级；第二，宜居度排名具有等级性、经济发展水平相关性以及城市品牌及知名度重合性等特征。在宜居度分级的基础上，利用地理加权回归对宜居度进行空间差异解释和分析，结果显示：（1）GDP参数贡献呈现“南高北低”的格局；（2）房地产投资（REI）和市容环境卫生维护支出（EOES）的参数贡献呈现“北高南低”的格局；（3）城区面积（UA）的参数贡献呈“东高西低”的格局。
The degree of livable comprehensive index system of central cities of the Yangtze River Delta was built from degree of living suitable, degree of environmental beauty, degree of social development and degree of economic pros- perity. By the method of entropy, we get the following results： （1） livable degrees of the 25 cities in the Yangtze River Delta can be divided into I to 1V levels; （2） the livable degrees of main cities in the Yangtze River Delta have three characteristics： hierarchical like the shape of ＂pyramid＂, level of economic development related, city brand and reputation coincidence. Geographically Weighted Regression （GWR） was used to estimate the reasons of principal component scores of the 25 cities in the Yangtze River Delta. The results showed that the contribution of GDP coefficient has the character of ＂North low and South high＂, real estate investigation （REI） and expenditure of environmental sanitation （EOES） have the character of ＂North high and South low＂ and urban area （UA） has the character of ＂East high and West low＂.
