城镇化、产业结构升级与中国城乡收入差距

Urbanization,Upgrading of Industrial Structure and Income Gap between Urban and Rural Areas in China

从产业结构、城镇化两个维度分析城乡收入差距,修正巴罗内生增长理论并借用泰尔指数构建理论模型证明城镇化、产业优化与城乡收入差距呈现倒"U"型关系,运用1996-2015年省级数据进行实证检验。研究结果表明:东中西部城镇化、产业优化与城乡收入差距在长期均有利于缩小城乡收入差距,其中城镇化水平提高对中部地区削减效应最大,东部最小;工业化后期二三产业层次提升对西部削减效应最大,东部最小;产业结构进一步优化至第三产业,对东部地区城乡收入差距具有显著缩减作用,中西部虽呈现负相关但不显著。

This paper analyzes the income gap between urban and rural areas from the two dimensions of industrial structure and urbanization,corrects Baro＇s endogenous growth theory and borrows Theil index theoretical model to prove that urbanization、industrial optimization and urban-rural income gap are presented a down ＂ U＂,Using the provincial data from 1996 to 2015for empirical tests.The research results show that the urbanization、industrial optimization and urban-rural income gap in the eastern,central and western regions are conducive to narrowing the urban-rural income gap in the long term,and the urbanization level is the largest in the central region,and the eastern region is the smallest.Further optimization to the second and third industry in the late stage of industrialization has the greatest effect on the western reduction,and the eastern reduction is the smallest.The industrial structure is further optimized to the third industry,which has a significant effect on the income gap between the urban and rural areas in the eastern region,while the central and western regions are negatively correlated but not significant.
