利用1995—2011年31个省区的三种类型收入不平等的非均匀面板测度数据,考察收入差距与经济发展水平之间的关系。实证发现：三种收入差距基尼系数关于人均实际GRP都呈倒U关系,收入不平等面临缩小的Kuznets拐点。近年来,城镇部门的收入差距已过倒U曲线的拐点,进入倒U曲线对称轴右半段的下降部分;农村部门和城乡之间的收入差距都没有到达转折点,而处于倒U曲线的上升阶段,但都由左向转折点靠近,不平等上升速度有所减缓。适当的政策能在一定程度上减少不平等,使中国收入不平等提前进入下降阶段。

This paper computes the Gini coefficients for 31 provinces in China during 1995 -2011, on which the relationship between income inequality and economic development is studied. The empirical evidence shows that three inequality variables reflecting the income difference all have an inversed - U relationship with real GRP per capita, and income inequality faces a decreasing Kuznets turning point. In recent years the urban inequality has passed the turning point of the inversed - U curve and entered the right - half decreasing part of inversed - U curve beyond the symmetric axis. However, rural inequality and the inequality between the urban and rural still locate the increasing part of the inversed - U curves and do not attain the turning point with a decreasing rate for inequality to approach the turning point. Control variables can drive the symmetric axis of income inequality in the rural sector and the rural - urban difference to move to the left. Suitable policies to some extent can not only reduce the inequality degree but also drive inequality to enter the decreasing stage beforehand.
