经济开放与收入差距:基于STR模型的分析

基于1978—2009年的时间序列数据,在总结相关传导机制的基础上,运用平滑转换回归模型就经济开放对收入差距的影响效应进行研究。结果表明:中国经济开放与收入差距之间的关系是非线性的,两者之间存在明显的体制转换动态特征。在1985年以前,经济开放对收入差距的效应为负;在1985年以后,经济开放对收入差距的效应为正。主要原因在于,经济地理效应和技术偏移效应逐渐替代了要素禀赋效应。

Economic Openness and Income Gap:Based on Smooth Transition Regression Model

Based on time series data of 1978-2009,this paper makes a study of impacts of economic openness on income gap in China with a non-linear smooth transition regression model.The research shows the relation between economic openness and inequality is non-linear,and has a dynamic characteristic of system transformation.Before 1985,the impact of openness on income gap is negative,after that,the impact of openness on income gap is positive.The reason is that influence of industrial spatial distribution and technology bias is stronger than that of factor endowment.
