对区域经济差异的测度,可以引入多项指标如最大最小值比、相对平均偏差、变异系数、基尼系数和泰尔指数等来满足对差异的直观、快速、准确、全面、有所侧重和差异构成的认识要求。以广东省数据为例,我们测算到广东最高最低地区间收入差距从1978年的4.39倍扩大到2007年的7.9倍;加权变异系数从1978年的0.497增长至2007年的1.45;加权相对离差率从1978年的0.293,增加至2007年的1.14;加权基尼系数从1978年的0.209,增加至2007年0.48。计算分析还表明,广东区域差异78%来自于珠三角地区与其他三个地区间的差异,22%来自于地区内差距。而地区内差异又主要是来自于珠三角地区。
The measurement of regional economic disparity can introduce a number of indicators such as maximum / minimum ratio, relative average deviation, coefficient of variation, Gini coefficient and the Theil index to meet the differences between the intuitive, rapid, accurate, comprehensive, focused and different Constitute the understanding of requirements. Taking the data of Guangdong Province as an example, we estimate that the income gap between the regions with the highest and the lowest in Guangdong has been widened from 4.39 times in 1978 to 7.9 times in 2007; the coefficient of variation of coefficients of variation has increased from 0.497 in 1978 to 1.45 in 2007; and the weighted relative deviation The rate increased from 0.293 in 1978 to 1.14 in 2007; the weighted Gini coefficient increased from 0.209 in 1978 to 0.48 in 2007. The calculation and analysis also show that 78% of the regional differences in Guangdong come from the differences between the PRD region and the other three regions and 22% from the intra-regional differences. The difference in the region is mainly from the Pearl River Delta region.
