河南省经济增长与城乡居民收入差距关系的实证分析

Empirical Research on Relationship between Urban-Rural Income Gap and Economic Growth in Henan Province

选取泰尔指数度量了河南省城乡收入差距,并运用协整检验和格兰杰因果关系检验,以及基于向量自回归模型的脉冲响应函数及方差分解等方法,实证分析了河南省1978～2009年的经济增长与城乡收入之间的关系。研究发现,经济增长与城乡收入差距之间存在长期均衡关系;经济增长对城乡收入差距的扩大具有很大的影响,而城乡收入差距的扩大对于经济增长存在着一定的制约作用。

This paper firstly measured the urban-rural income gap in Henan province with Theil index.Following that,by means of co-integration test,Granger causality test,IRF（impulse response function） and variance decomposition methods which are based on vector autoregressive（VAR） model,this article empirically analyzed the relationship between the economic growth and urban-rural income gap in Henan province from 1978 to 2009.It was eventually found that there existed long-term equilibrium relationship between the economic growth and urban-rural income gap;the economic growth had a great effect on the enlargement of urban-rural income gap;meanwhile,the enlargement of urban-rural income gap also constrained its economic growth to some extent.
