中国长三角地区城市增长极协调发展水平研究

Level of coordinated development of urban growth pole in Yangtze River Delta region of China

利用因子分析方法对长三角16个城市增长极2007—2011年的协调发展水平进行实证研究。结果显示:经济、社会、环境和综合指标的偏度分别为1.821,-0.096,0.743和1.373,峰度分别为3.618,-0.722,-0.774和1.607,表明长三角地区城市增长极的差异性主要来源于经济发展水平差异,社会和环境发展水平的较小差异则有利于长三角地区综合发展水平差异的缩小。因此,长三角地区城市在维持现有极化体系的基础上,应结合自身资源禀赋和历史发展积累,促进要素自由流动,提升协调发展水平。

Empirical researches on the level of coordinated development of growth pole of 16 cities in the Yangtze River Delta region during 2007- 2011 are performed by using the method of factor analysis. The results show that the deviations of economic,social,environmental and comprehensive indices are respectively 1. 821,- 0. 096,0. 743 and 1. 373,and their peak values are respectively 3. 618,- 0. 722,-0. 774 and 1. 607,indicating that the difference of urban growth pole in the Yangtze River Delta region comes mainly from that of economic development level,and the small differences of social and environmental development levels are in favor of reducing the difference of the comprehensive development level in the Yangtze River Delta region. Therefore,maintaining the existing polarization system, the cities in the Yangtze River Delta region should combine with its own resources and historical accumulation to promote the free flow of factors and to raise the coordinated development level.
