基于熵权 TOPSIS 法的苏北地区城市中心性评价

摘要

An evaluation index system of the urban centricity was established based on the entropy-weight TOPSIS method , and an empirical analysis of the urban centricity of major cities in Northern Jiangsu was made from 7 aspects of the comprehensive economic , science and technology innovation , competition ability , ag-glomeration ability , transportation accessibility , information exchange and sustainable development .The anal-ysis results dating from the figure from 2010 to 2014 revealed that Xuzhou got the highest score indicating its significant urban centricity , which was mainly presented in the aspects of transportation accessibility , science and technology innovation .While other 4 cities have their own advantages and disadvantages , the regional gap among them was relatively small , and all of them was in a comparatively lower state of balanced development .%基于熵权TOPSIS法，从综合经济、科技创新、城市竞争、集聚带动、交通通达、信息交流和可持续发展7个方面构建起城市中心性综合评价指标体系，对苏北地区主要城市的中心性进行了实证分析．2010～2014年各项指标数据的分析结果表明：徐州市的城市中心性综合得分最高，城市中心性显著，其中心性主要体现在科技创新与交通通达两个方面．其他4个城市中心性的优劣势各有不同，城市间差距较小，整体处于较低水平的均衡发展状态．
