摘要
基于2008—2021年省级面板数据的二次项修正模型,以两种“借用规模”视角考察多中心空间结构对城乡融合的影响及其作用机制。实证结果表明:第一,多中心空间结构对城乡融合的影响呈先上升后下降的倒U形特征。当前除了山东、广东和内蒙古三个地区已出现超出最优多中心水平的现象外,全国大部分地区的城乡融合尚处于随着多中心水平发展而逐步提升的阶段。第二,对于东部地区来说,交通基础设施和市场一体化是多中心空间结构影响城乡融合的有效途径,而中、西部地区由于多中心空间结构发展并未达到最优规模,交通基础设施和市场一体化的作用并未凸显。第三,城市之间的地理距离在多中心空间结构的城乡融合效应中发挥着显著的正U形调节作用。
Based on the quadratic correction model of provincial panel data from 2008 to 2021,the study investigates the effects and mechanisms of polycentric spatial structure on urban-rural integration from two“borrowed scale”perspectives.The study finds that:(1)The spatial structure of polycentres and urban-rural integration have an inverted U-shaped characteristic of rising and then falling.At present,except for the three regions of Shandong,Guangdong and Inner Mongolia,which have already exceeded the optimal level of polycentricity,the urban-rural integration of most regions of the country is still in the stage of gradual improvement with the development of polycentricity.(2)For the eastern region,transport infrastructure and market integration are effective ways for the polycentric spatial structure to influence urban-rural integration,while in the central and western regions,the development of the polycentric spatial structure has not reached the optimal scale,and the role of transport infrastructure and market integration has not been highlighted.(3)Geographic distance between cities plays a significant positive U-shaped moderating role in the urban-rural integration effect of polycentric spatial structure.
