陕西省城乡收入差距与经济增长关系的实证分析

Empirical Study on the Relationship Between Urban-rural Income Gap and Economic Growth of Shaanxi Province

借用Eviews5.0,运用陕西省1980-2007年的统计数据对其城乡收入差距与经济增长的关系进行协整与格兰杰因果关系检验。结果表明,两者之间在长期中存在稳定的均衡关系,在这28年间,经济增长对城乡收入差距的总体影响是拉大的。从格兰杰因果关系检验的结果来看,短期中经济增长会在一定程度上扩大城乡收入差距,而收入差距的扩大却不能刺激经济的增长;在长期中,陕西省城乡收入差距与经济增长之间存在着稳定的双向因果关系。

By the use of Eviews5.0,and with the data of Shaanxi Province from 1980-2007,this paper analyzed the cointegration and Granger causality relationship between the urban-rural income gap and economic growth,and the empirical result shows that they have equilibrium relationship in the long run,and during the 28 years,the economic growth has enlarged the urban-rural income gap.It can be seen from the Granger causality test that,in the short period of time,the economic growth can enlarge the urban-rural income gap in some extent,but the urban-rural income gap cannot bring economic growth;while in the long run,there is stable dual causality relationship between the economic growth and the urban-rural income gap of Shaanxi Province.
