长江中游城市群城乡共同富裕水平测度及区域差异

Measurement and Regional Difference of the Urban-Rural Common Prosperity of the Urban Agglomerations in the Middle Reaches of the Yangtze River

城乡共同富裕是实现中国式现代化共同富裕目标的关键路径。文章基于“城乡共建—城乡共享—城乡共荣”框架构建城乡共同富裕水平的评价指标体系,运用熵值法、空间自相关和Dagum基尼系数测度分析了2011—2020年长江中游城市群城乡共同富裕水平的时序演变和区域差异。结果表明:①研究期内长江中游城市群城乡共同富裕水平整体呈现出“上升—下降—上升”的复杂波动态势,内部三大城市群中武汉都市圈显著高于其他城市群,各城市的城乡共同富裕水平及排名存在明显年际变化,高值区域呈点状分散分布,城市群边缘区域则存在“塌陷”现象。②长江中游城市群城乡共同富裕水平暂未形成明显的空间集聚态势,城市群内部也暂未发现明显的辐射集聚效应。③长江中游城市群城乡共同富裕水平的区域差异较为明显,主要来源于武汉都市圈和长株潭都市圈之间的水平差距。基于研究结论,从产业振兴、服务共享、资源统合、空间协同等方面提出政策建议。

Urban-rural common prosperity is the key path to achieve the goal of common prosperity in Chinese-style modernization.This study proposes an evaluation framework,based on the policy agendas of co-construction,sharing,and mutual prosperity,to assess the level of urban-rural common prosperity of urban agglomerations in middle reaches of the Yangtze River from 2011 to 2020.It analyzes the spatiotemporal evolution and regional differences of urban-rural common prosperity of urban agglomerations in middle reaches of the Yangtze River by the means of entropy method,spatial autocorrelation,and Dagum Gini coefficient.The results show that:1)The overall level of urban-rural common prosperity exhibited a complex"rise-fall-rise"trend in 2011-2020.Wuhan metropolitan area displayed a significantly higher level of urban-rural common prosperity than other regions,while the rank and level of urban-rural common prosperity fluctuated widely from year to year,high-value regions were sparsely distributed,it showed a"collapse"phenomenon in the marginal areas of urban agglomerations.2)There were no significant spatial clustering patterns or radiation effects within the urban agglomeration.3)Regional differences of urban-rural common prosperity level were relatively obvious,mainly due to the gap between Wuhan metropolitan area and Changsha-Zhuzhou-Xiangtan metropolitan area.Based on the research conclusions,it puts forward policy recommendations from the aspects of industrial revitalization,service sharing,resource integration and spatial cooperation.
