城市群落的崛起、经济绩效与区域收入差距——基于京津冀、长三角和珠三角城市圈的分析

The Rise of Urban Cluster,Economic Performance and Regional Income Disparity Based on the Metropolitan Area of Jing-Jin-Ji,Yangtze River Delta and Pearl River Delta

本文以京津冀、长三角和珠三角城市圈地区为样本,运用断点回归和分位数回归研究城市群落崛起过程对该地区经济绩效和收入差距的影响,实证结果表明：第一,城市群落的形成提高了该区域的经济绩效;第二,在2003年和2004年城市群落崛起过程中,落后地区受益最大,区域收入差距呈现出缩小的趋势;第三,2005~2007年,受益最大的地区是中等发达地区,城市群落的发展进一步缩小了中等发达地区与发达地区之间的收入差距,但是在2007年,落后地区和其它地区之间的收入差距出现了扩大的趋势。

This paper utilizes the regression discontinuity and quantile regression method to study the effect of metropolitan area on regional economic performance and disparity based on the metropolitan area of Jing-Jin-Ji,Yangtze River Delta and Pearl River Delta.The empirical study shows that during the process of urban cluster in 2003 and 2004,the region which has the lowest initial development status will benefit the most,which implies the regional disparity is decreasing.However,from 2005 to 2007,the region which has the medium initial development status benefits the most and moreover in 2007 the region which has the lowest initial development status benefits the least.Consequently,the urban cluster decreases the disparity between the medium development region and the highest development region.Furthermore,in 2007 such effect increases the disparity between the lowest development region and the others.
