城镇化对城乡收入差距的影响——基于2005-2017年省级面板数据空间计量研究

The Influence of Urbanization on the Income Gap between Urban and Rural Areas:a Spatial Measurement Research Based on Provincial Panel Data from 2005 to 2017

基于2005-2017年的31个省级面板数据,通过构建空间面板模型,对城镇化与城乡收入差距之间的关系进行实证分析.结果表明:城镇化与城乡相对收入差距之间呈现"倒U型"关系,城镇化率大于0. 697 8时,城镇化率的提高对缩小城乡收入差距起正向促进作用;城镇化率小于0. 586 6时,城镇化率的上升将对缩小城乡收入差距起反向作用.人均GDP和消费价格指数对城乡收入差距的影响是负向显著的;城镇化与人均GDP的交互项和城镇化与城镇失业人口登记率的交互项对城乡收入差距有显著为正的影响.最后,根据研究结果,就城镇化发展水平对缩小城乡收入差距提出相关建议.

Based on the panel data of 31 provinces from 2005 to 2017,this paper conducts an empirical test on the relationship between urbanization and urban-rural income gap by building a spatial panel model. The results show that there is an inverted u-shaped relationship between urbanization and urban-rural income gap.When the urbanization rate is greater than 0. 697 8,the improvement of urbanization rate plays a positive role in promoting the narrowing of urban-rural income gap;when the urbanization rate is less than 0. 586 6,the increase of urbanization rate will play a negative role in narrowing the urban-rural income gap. Per capita GDP and consumer price index have significant negative effects on the income gap between urban and rural areas. The interaction between urbanization and per capita GDP,and the interaction between urbanization and urban unemployment registration rate have a significant positive impact on the urban-rural income gap. Finally,according to the research results,the paper puts forward some suggestions on how to narrow the income gap between urban and rural areas.
