区域经济差异常用测度方法与评价——以河南省为例

Regional Economic Inequality Measurements and Their Evaluation——A Case Study of Henan Province

在整理1992—2012年间研究区域经济差异的580篇核心期刊文献的基础上,统计出研究区域经济差异的几种常用测度方法:变异系数、Theil指数、标准差、基尼系数和空间自相关分析,把这几种测度方法分为非空间测度方法和空间测度方法两大类.同时,分析了这些测度方法在构造上的差异,然后通过不同测度方法测度了1999—2011年河南省县域经济差异演变轨迹.研究认为:非空间测度方法的结果表明,在探究区域经济差异变化机制时,应以长期的变化趋势作为分析的基础;Global Moran’s I,Moran散点图和Local Moran’s I三种空间测度方法相结合可以用来研究区域经济总体空间差异、局部空间差异的演变以及经济发展的局部空间格局变化.最后,从理论和实际应用两方面探讨了不同测度方法的适用范围及其在测度区域经济差异中的优势和局限.

Based on the literature review of 580 core journal papers from 1992 to 2012 on the topic of regional economic inequality,several commonly used measurements were summarized,such as coefficient of variation,Theil index,standard deviation,Gini coefficient and spatial autocorrelation indicators. These measurements can be divided into non-spatial and spatial measurement categories. Based on the various features of these measurements,we adopt them in a case study of county-level regional inequality in Henan Province from 1999 to 2011. The study reveals that the non-spatial measurement tends to produce reliable results for a longer time period. Global Moran’s I,Moran scatter plot and local Moran’s I should be used jointly to detect spatial differences in economic development and the evolution at both local and global scales. The paper is concluded with a discussion of applicability and limitation of these measurements,from both theoretical and empirical perspectives.
