城乡消费差异、城乡收入差距与经济发展

Consumption Difference,Income Gap between Urban and Rural Areas and the Economic Development

基于消费函数理论,在控制城乡收入差距的前提下,文章通过面板固定效应模型考察了经济发展对城乡消费差异的直接效应,再利用非参数局部线性回归估计法通过验证城乡收入差距与经济发展之间是否符合库兹涅茨假说考察了经济发展对于城乡消费差异的间接效应,最后通过直接研究经济发展与城乡消费差异的函数关系形态考察了不同经济发展水平下前者对于后者的直接效应与间接效应的作用结果。实证分析显示无论是对于城乡收入差距还是城乡消费差异,两者与经济发展之间均存在倒U型关系。基于以上研究结论,针对处于不同发展阶段的地区,就如何处理发展与公平,提出了建议。

Based on the theory of consumption function,under the assumption of invariant income gap between urban and ru ral areas,using panel-data fixed effect model,the paper analyzes the direct effect of the economic development on the con sumption difference between urban and rural areas,then the local linear regression is applied to study the relationship between the income gap and the economic development by verify the existence of Kuznets inverted U-shaped curve,finally,the com prehensive effect of the economic development on the consumption difference is studied through examining their relationship di rectly.The result shows that the inverted U-shaped curve exists between not only the income gap but also the consumption dif ference and economic development.Based on the results above,advice is given to regions at different development stage on how to deal with the development and fairness.
