城乡收入差距对中部地区经济增长的非线性影响研究——基于面板门限模型分析的证据

The Nonlinear Effects of Urban- rural Income Disparity on Economic Growth in Central China——Evidence from the Analysis of a Panel Threshold Model

基于中部地区地级市层面,构建城乡收入差距对经济增长影响的非线性模型;在实证分析中,针对三种不同情形开展整体分析与不同类型区的比较分析。结果表明:城乡收入差距扩大在一定程度上对经济增长具有促进作用,但随着这一差距的持续扩大并跨越门限值后,将对经济增长产生显著性的阻碍作用;不同类型区的两种划分情形下的结果同样表明,随着城乡收入差距的持续扩大,收入差距扩大地区相对于收入差距缩小地区将可能更快地由城乡收入差距对经济增长存在正效应的阶段跨入对经济增长存在负效应的阶段。

Introducing the panel threshold model has provide a new support to explore the nonlinear effects of urban - rural income disparity on economic growth. This paper built the nonlinear model about urban - rural disparity and economic growth in central region under the analysis, this paper compares the analysis in whole tion. The empirical results show that the expanding consideration of Hansen＇ s threshold model. During the empirical region as well as different parts of region in three kinds of situa- income disparity has a positive role on economic growth, but with the continued expansion of this disparity, and after crossing the threshold, it will has significant adverse effect on economic growth. In the situation of distinguishing two kinds of the region, with the continuing expanding disparity, the region which have the widen income disparity will reach the stage that urge the effect transform from positive into negative quicker than the region have the reduced income disparity.
