重庆市区域板块城镇化与城乡收入差距实证研究

The Empirical Analysis of Regional Plate of Urbanization and Urban-rural Income Gap

将重庆38个区县分为主城核心区、1小时经济圈、渝东北翼、渝东南翼共4个区域板块,运用面板数据向量自回归模型对2000-2012年全市层面和各区域板块城镇化与城乡收入差距的关系进行现实考察和计量分析。结果发现:重庆市绝大多数区县城乡收入泰尔指数曲线总体上呈现出显著的倒U型特征,但在倒U型曲线顶点的绝对数值和出现时间具有鲜明的区域差异;全市层面和各个区域板块城乡收入泰尔指数的脉冲响应过程存在显著差异。仅有主城核心区城乡收入差距对城镇化率冲击会最终作出反向脉冲响应,即城镇化率提高会对城乡收入差距产生缩小效应。根据实证结果,要在推进新型城镇化的同时逐步缩小城乡收入差距,必须尽快破除各种导致城乡收入分配不平等的制度约束。

The paper has divided 38 counties of Chongqing into four regions,including core urban area,1hour economic circle,northeast of Chongqing,and southeast of Chongqing.Using the panel data of vector autoregressive model,the paper analyzes the relationship between urbanization and urban-rural income gap on the citys urbanization level and the regional plate from 2000 to 2012.The results show that：Theil index of urban-rural income curve shows the characteristics of significant inverted U-shaped at the vast majority of districts in Chongqing.But in the vertex of the inverted U-shaped curve,the absolute quantity and emerging time have distinct regional differences.The urban-rural income＇s Theil index of impulse response process has a significant difference in the city and regional plates.Only the urban-rural income gap of core area has reverse pulse response to the urbanization rate.In other words,the improvement of urbanization rate will narrow the income gap between urban and rural areas.According to the empirical results,this paper proposes that at the same time of advancing the new urbanization,gradually narrowing the income gap between urban and rural areas,we should accelerate to break down the institutional constraints which lead to income distribution inequality of urban and rural.
