四川省区域经济差异的时空演化——基于Theil指数的分解

本文以四川5大经济区域作为考察的地域单元,采用可以多层次分解的Theil指数测量了1998-2009年间四川5大经济区域之间、区域内部以及总体区域差异的时空演变.研究发现:5大经济区域内部、区域之间以及总体差异都呈现倒“U”型变化特征,其中区域内部的差异对总体差异的贡献度不断增加,而区域之间的差异对总体差异的贡献度不断减少.从5大区域内部差异看,成都经济区和攀西经济区内部差异较大,其余3大区域的内部差异较小.

Developing Feature of Regional Economic Disparity in Sichuan Province -Decomposition Analysis with Thiel Index

This paper takes five economic regions as investigated regional unit,and measures internal disparity,total disparity and disparity among five regions from 1998 to 2009 in Sichuan province with Theil index.It discovers that internal disparity,total disparity and disparity among the five regions have an inverted "U" shape trend.The contribution of internal disparity to total disparity presents up-tread,but the contribution of disparity among the five regions to total disparity presents down-tread.It can be seen from the internal disparity in the five regions that the internal disparity of Chengdu economic zones and Panxi economic zones are significant,internal disparity of other three regions is small.
