四川省五大区域经济发展差异的实证研究

基于四川省五大区域1998～2009年GDP及人口数据,首先采用变异系数分析人均GDP的发展变化情况,然后采用锡尔指数及其分解式,对四川省区域总差异、区域间差异以及区域内部差异进行计算和分析.变异系数和锡尔指数分析结果均表明,区域差异呈倒U形特征,其中区域间差异和内部差异所占比例相当;通过成都和各区域经济核心的带动作用,将有利减小四川五大区域经济发展的差异.

Empirical Study of the Economic Development Differences in the Five Regions in Sichuan

Based on data of GDP and population from the years of 1998-2009 for the five regions of Sichuan,by employing Variation Coefficient,an analysis is made of the developing trend of the GDP per capita.Then by use of the Theil index and its decomposition formula,some calculation and analysis is done to work out the inter-regional and intra-regional differences.Both of the Theil index and the Variation Coefficient analysis indicate that the overall difference takes an inversed U trend,with a basically even proportion between the inter-regional difference and intra-regional difference;the vigorous driving impetus of Chengdu and other economic cores will eventually even out the regional differences of economic development among the five regions.
