基于锡尔系数的江苏省区域经济差异分析

An Analysis on the Economic Diversity among Areas in Jiangsu Province Based on Theil Index

本文采用人均GDP、GDP和人口指标对1978年以来江苏省区域经济差异水平进行定量测度,基于三大地带—市—县三级结构的地域行政单位,运用锡尔系数一次、二次分解对全省的区域经济差异进行细分测度,将江苏省经济发展差异分解为苏南、苏中、苏北三大地带间的差异、三大地带市内之间的差异以及各市的内部差异三部分,通过分析发现,江苏省经济发展差异主要来自三大地带间差异,其次是市内差异,各地带市间差异最小。

In this article, the author adopted per GDP, total GDP and population as target, analyzed the economic differences among the areas in Jiangsu province from 1978 to now quantiflcationally, then based on the different regionalism, fractionized the diversity to find the source of the whole differences through decomposed the Theil Index. Via the decomposition, we can found that the whole differences in Jiangsu province was made up of three parts, the most distinct one is the difference from the three belts in the province, in the next place, the difference in the cities plays an important part also, finally, the most inapparent one is the difference among the cities in each belt.
