摘要
本文选取1978～2007年中国30个省市的面板数据,运用面板单位根检验、阈值面板数据模型对我国城市化和城乡收入差距的关系进行了检验和估计。实证结果表明:我国城市化对城乡收入差距的影响存在单一阈值效应,城市化对城乡收入差距的作用并非简单地促进或者抑制,其效应还要取决于城乡收入差距本身的水平,当城乡收入差距水平较高(即城乡居民收入比大于2.54)时,扩大城市化将扩大城乡收入差距;当城乡收入差距水平较低时(即城乡居民收入比小于或者等于2.54),加速城市化能有效地缩小城乡收入差距。
This paper researches on the relationship between the level of urbanization and rural - ~ income disparity for the provincial panel data from 1978 to 2007. Based on the unit root tests, threshold models for panel data, the equilibrium relation of the level of urbanization and rural - urban income disparity are analyzed. The empirical results show that there is a single threshold effect between the level of urbanizafion and rural - urban income disparity in china. Moreover, the effect of the urbanization to the rural - urban income disparity also depends on the level of rural - urban income disparity itself. The urbanization process would enlarge the rural - urban income disparity while the level of rural - urban income disparity is high and reduce the disparity while it＇ s low.
