长江三角洲城市群城市规模分布与经济规模分布的比较研究

A Comparative Study of City Size Distribution and Economic Scale Distribution of Yangtze River Delta Urban Agglomeration

本文建立与城市规模、城市首位度和城市规模基尼系数相应的经济规模、经济首位度和经济规模基尼系数指标,运用2007-2012年的统计数据测算各指标值,对长江三角洲城市群城市规模分布与经济规模分布进行分析比较。得出两大结论:第一,长江三角洲城市群城市规模与经济规模具有高度的正相关性,但目前城市规模与经济规模的增长率都呈下降趋势。第二,长江三角洲城市群内人口与经济规模高度集中,尤其是最大城市上海市人口集中度严重。据此,笔者提出了长江三角洲城市群进一步城镇化的建议:突破行政区域的限制,建立上海都市圈。

This paper established the economic-scale, economic primacy index and economic Gini coefficient that correspond to the city-size, city primacy index and city Gini coefficient. The authors utilize the statistical dma of 2007-2012 to calculate each index value, analyze and compare the city-size distribution and the economic scale distribution of Yangtze River Delta Urban Agglomeration. Finally we draw the following two eonelusions： Firstly, currently The Yangtze River Delta Urban Asslomeration＇ S growth rate of city size and economic scale show a declining trend. Secondly, The Yangtze River Delta Urban Agglomeration＇s people and economic scale are highly concentrated, especially the biggest city Shanghai has a serious demographic concentration.
