摘　　要：共同富裕是中国式现代化的本质要求,缩小地区间收入差距是推进共同富裕的重要途径。本文利用夜间灯光数据,探讨了中国城市群空间结构演变对地区间收入差距的影响及作用机制。研究发现,相比单中心模式,城市群多中心化具有缩小地区间收入差距的积极效应,为多中心结构的收入收敛效应提供了证据支持。中介效应检验证实,城市群的多中心结构主要通过扩大劳动力流动规模及深化城市之间的功能分工,起到缩小地区间收入差距的效果。其中,频繁快速的劳动力流动发挥了相对更强的中介效应。因此,可积极发挥多中心空间发展策略的积极作用,促进劳动力的自由流动、深化城市间功能分工,从而为缩小地区间收入差距、推进共同富裕创造有利的发展环境。Achieving common prosperity is the essential requirement of Chinese path to modernization. Reducing regional income disparity is one of the important ways to achieve common prosperity. From the viewpoint of common prosperity, this paper aims to empirically examine the impacts and mechanism of the evolution of urban agglomeration spatial structure on the regional income disparity within urban agglomeration based on night-time light data analysis. It is found that polycentric structure of urban agglomeration can promote reduction of regional income disparity compared with the single-center model. This result provides an evidence for convergence effect of income disparity under the polycentric structure. The results of mediation effect test confirm that labor mobility and functional specialization across the cities are the two pathways to reduce regional income disparity within urban agglomeration. In contrast, frequent and rapid labor mobility plays a relatively stronger mediating effect. Therefore, the positive role of the multi-center space development strategy can be actively played to promote the free flow of labor and deepen the functional division of labor between cities, thereby creating a favorable development environment for narrowing the income gap between regions and promoting common prosperity.
