长江经济带产业结构优化与城乡收入差距--基于空间杜宾模型

On Optimization of Industrial Structure And Urban-Rural Income Gap in The Yangtze River Economic Belt——Based on Spatial Dobbin Model

产业结构优化对调整收入分配具有重要作用,而这两项也是长江经济带建设的重要任务。鉴于此,利用2000-2019年长江经济带9省2市的面板数据,借助于空间杜宾模型,从产业结构合理化与高级化两个方面对城乡收入差距的影响进行实证研究。研究结果表明:长江经济带产业结构优化和城乡收入差距均存在空间集聚特征;产业结构高级化对城乡收入差距具有扩大作用,而产业结构合理化却能缩小城乡收入差距;同时,由于空间溢出效应的存在,本区域与邻近区域的产业结构高级化作用相互抵消导致扩大效应较小,而本区域和邻近区域的产业结构合理化的正向作用相互叠加更能显著缩小城乡收入差距。

Industrial structure optimization plays an important role in adjusting income distribution,and these two tasks are also important for the construction of the Yangtze River Economic Belt.In view of this,panel data of 9 provinces and 2 cities in the Yangtze River Economic Belt are collected from 2000 to 2019,and an empirical study on the spatial spillover effect of the urban-rural income gap are conducted from two aspects of industrial structure rationalization and upgrading with the help of Spatial Dubbin Model.The results show that the upgrading and rationalization of industrial structure have significant spatial effects on urban-rural income gap,and the upgrading of industrial structure plays a significant role in widening the urban-rural income gap in this region,while the upgrading of industrial structure in neighboring regions can narrow the urban-rural income gap in this region.The rationalization of industrial structure in this region and neighbors can significantly reduce the urban-rural income gap,and the spatial spillover effect of industrial structure rationalization is more obvious.
