摘　　要：采用2000—2017年省级面板数据和Landscan人口动态分布数据,考察多中心空间发展模式对我国城乡收入差距的影响、作用机制以及约束条件。研究发现:多中心空间结构对城乡收入差距的影响呈显著的先缩小后扩大的U形趋势;部分省份因多中心水平过高而出现城乡收入差距加剧的问题,但多数省份的多中心空间结构尚未达到最优水平。中介效应检验结果表明,市场一体化和交通基础设施改善是多中心空间发展模式影响城乡收入差距的重要途径,而城市之间的地理距离在多中心空间发展模式影响城乡收入差距的过程中发挥显著的负向调节作用。Using provincial panel data from 2000—2017 and Landscan population dynamic distribution data,this paper investigates the impact,mechanism and constraints of the polycentric spatial development pattern on China’s urban-rural income gap.It is found that,firstly,the impact of polycentric spatial structure on urban-rural income gap shows a significant U-shaped trend of narrowing.Secondly,the urban-rural income gap in some provinces in China have been aggravated due to the excessive high level of poly-centricity,but the polycentric spatial structure in most provinces has not reached the optimal level.Thirdly,the mediation effect test shows that market integration and transport infrastructure improvement are important ways for the polycentric spatial development pattern to influence the urban-rural income gap.Finally,geographical distance between cities plays a significant negative regulatory role in the process of the polycentric spatial development model affecting the urban-rural income gap.
