江苏省区域经济差异的多尺度研究

Study of Multi-scale on the Regional Economic Disparities in Jiangsu Province

运用多阶段The il系数嵌套分解法,从空间尺度研究江苏省区域经济差异问题。基本结论是:从市级行政区域单元来看,北部市级之间差异的变化趋势和全省的变化趋势基本是一致的,中部和南部市级之间的差异一直相对较小,而且变化趋势较为缓慢,但是三大地带之间差异一直在增大。从县级行政区域单元来看,市内差异是全省整体差异的重要构成部分,市内差异对于全省整体差异的贡献比三大地带之间差异和市际差异的贡献显著得多。

By using the multi-stage nested Theil decomposition method ,this paper studies the spatial scales of regional economic disparities in Jiangsu Province of China. The main conclusions are ： （ 1 ） The regional economic disparities in Jiangsu Province, including the disparities within-city, between-city, within-region（ the south, central and north regions） and between-regions,have existed since 1978. （2）The first stage decomposition of Theil index shows that the dynamic trend of disparity in the northern region is consistent with that of whole Jiangsu Province, the disparity in the central and southern regions remains small, and the evolution is rather slow, the disparity be- tween the three regions has been continuously increasing. （3）The second stage decomposition of Theil index reveals that the within-city disparities is the most significant component of all the overall regional inequalities, which is more significant than that of the between-city and between-region disparities components, constituting the important part of the overall regional inequalities. In addition, the influence of within-city disparities in the northern region on the overall regional inequlities is more significant than that of in the other two regions, and, the influence in the southern region is more significant than that of in the central region.
