摘　　要：行政区划调整作为空间治理的制度支撑,是优化资源配置的重要举措,对促进区域均衡发展具有深远影响。论文基于2013—2021年中国272个城市的面板数据,采用空间双重差分模型探究了区界重组这一特殊的行政区划调整方式对区域均衡发展的影响,并进一步分析了以城市形态多中心为中介变量的影响机制。结果表明,区界重组不仅有利于促进本地城市的均衡发展,而且对邻近地区的均衡发展也产生了积极的空间溢出效应。机制检验表明,在行政区划调整背景下,城市空间形态优化是驱动区域均衡发展的重要路径。区界重组能够通过提升城市形态多中心水平从而减少区域发展的不平等。异质性分析表明,不同城市的区界重组对区域均衡发展的影响存在显著差异。相较于西部地区而言,东部和中部地区城市的区界重组对区域均衡发展的提升作用更显著。区界重组对大城市和中等城市存在显著的促进作用,而对超大城市、特大城市和小城市的影响不显著。未来应根据不同城市的发展条件,审慎开展行政区划调整,因地制宜地推进以区界重组为导向的城市多中心建设,从而促进城市空间优化和区域均衡发展。Administrative division adjustment as an institutional support for spatial governance is an important measure to optimize resource allocation,and it has profound effects on promoting balanced regional development.Based on the panel data of 272 cities in China from 2013 to 2021,this study used the spatial difference-in-differences method to explore the impact of district-level administrative restructuring,a special type of administrative division adjustment,on balanced regional development,and further analyzed the mediation mechanism of urban morphological polycentricity.The results show that district-level administrative restructuring is not only beneficial to promoting balanced regional development in local regions,but also has positive spatial spillover effects on neighboring regions.Mechanism analysis show that under the background of administrative division adjustment,urban form is an important driving factor for balanced regional development.Specifically,district-level administrative restructuring can reduce regional development inequality by improving the level of urban morphological polycentricity.Heterogeneity analysis show that the impact of district-level administrative restructuring on balanced regional development varies across regions.Compared to the western region,the positive effects of such restructuring on balanced regional development are more significant in the eastern and central regions.The restructuring has significant promotional effects in large cities and mediumsized cities,while the effects in mega-cities,super-large cities,and small cities are not significant.In the future,we should prudently carry out administrative division adjustment and urban spatial transformation according to the development conditions of different cities,and promote the construction of urban polycentricity by districtlevel administrative restructuring according to local conditions,in order to promote balanced regional development.
