我国经济格局与收入差距演变关系探讨

On the Relationship Between the Changes of Economic Spatial Pattern and Evolutions of Income Gap in China in Recent Years

对区位基尼系数和收入基尼系数的计算方法讨论后,利用区位基尼系数考查了近年来我国大陆地区经济活动空间格局的变化状况;探讨了混合样本总体收入基尼系数的计算方法,并据此分析了2002—2010年我国收入差距的演变特征。研究发现,2006年前区位基尼系数单调上升,2006年后区位基尼系数单调下降,说明近年我国经济活动集聚与扩散的拐点出现在2006年;而在2002—2010年收入基尼系数表现出波动上升的特征。研究认为,我国经济格局变化对收入差距演变产生滞后影响,相比于区域经济差距问题,缓解收入差距扩大显得更加紧迫。

This paper discusses the calculation methods of Location-Gini-Coefficient and Income-Gini-Coefficient, tests the changes of economic activity spatial pattern in Chinese mainland in recent years, researches on the calculation methods about the mixed sample overall income Gini-coefficient, and analyses the income disparity variation characteristics in Chinese mainland from 2002 to 2010. We find the Location-Gini-Coefficient increasing monotonically before 2006 and decreasing monotonically after 2006, it means the inflexion point of agglomeration and diffusion emerged in 2006. The Income-Gini-Coefficient shows fluctuant increasing feature in 2002-2010. The main conclusions include that the economic spatial pattern changes have lag-effects on the income disparity evolutions, and mitigating the income disparities appear more pressing compared to the regional economic gaps.
