改革开放以来,我国经济增长速度举世瞩目,但是同时收入分配不平等程度也在逐渐扩大。这说明不平等与经济增长之间可能具有一定关系。本文采用计量模型选用我国1982年到2009年的基尼系数和人均国内生产总值对不平等和经济增长进行计量分析。通过时间序列平稳性检验以及协整检验,证实了两者具有长期均衡关系。并且这种均衡关系构成了单向的因果关系——经济增长是导致收入分配不平等的Granger原因,即经济增长会促进收入分配不平等的扩大。 Since the reform and opening up, the rate of economic growth in our country has drawn worldwide attention, but at the same time the degree of inequality in income distribution has also gradually expanded. This shows that there may be some relations between inequality and economic growth. In this paper, we use the econometric model to select China’s Gini coefficient and per capita GDP from 1982 to 2009 to measure inequality and economic growth. Through time series stability test and co-integration test, it is confirmed that the two have a long-term equilibrium relationship. And this equilibrium constitutes a one-way causal relationship - economic growth is the Granger cause of inequality in income distribution, that economic growth will promote the expansion of income inequality.
