This paper constructs an evaluation index system of the common prosperity level in the Yangtze River Delta region from four dimensions:co-construction,sharing,co-development and co-association,then measures the common prosperity level of 41 cities in the region from 2010 to 2020,and finally makes an empirical analysis of its spatiotemporal characteristics,dynamic evolution trend and antecedent configuration.The results go as below:(1)During the observation period,the level of common pros-perity in this region exhibits a consistent upward trajectory with notable variations among cities.The ranking pattern of Shanghai>Zhejiang>Jiangsu>Anhui is maintained for a long time,and the spatial pattern of decaying from single core and poly-center to periphery is formed.(2)During the study period,there is a significant spatial positive correlation between the common prosperity levels in this region,characterized by"H-H"and"L-L"agglomeration types.Meanwhile,the common prosperity level of cities is affected by the spatial spillover effect,reflecting the characteristics of club convergence and spatial dependence.(3)The enhance-ment of common prosperity levels in this region is a consequence of synergistic factors,which can be summarized into three lead-ing paths:ternary interweaving type of"innovation-green-openness",multi-factor synergism type of"innovation-green-coordi-nation-openness",and binary interaction type of"openness-sharing".
