长三角地区共同富裕水平的时空演变特征与组态机制

Spatiotemporal Evolution Characteristics and Configuration Mechanism of Common Prosperity Level in the Yangtze River Delta Region

文章从共建富裕、共享富裕、共生富裕、共联富裕4个维度构建了长三角地区共同富裕水平评价指标体系,测度了2010—2020年该地区41个城市的共同富裕水平,并对其时空特征、动态演进趋势及前因组态进行了实证分析。结果表明:(1)观察期内该地区共同富裕水平呈稳步上升趋势,城市间差异明显“,上海>浙江>江苏>安徽”的格局长期维持,且形成从单核心与多中心向外围递减的空间格局;(2)研究期内该地区共同富裕水平存在显著的空间正相关关系,主要以“H-H”“L-L”集聚类型为主,同时城市共同富裕水平受空间溢出效应影响,体现出俱乐部趋同和空间依赖特征;(3)该地区共同富裕水平提升是多因素协同作用的结果,可归纳为“创新-绿色-开放”三元交织型“、创新-绿色-协调-开放”多因素协同型“、开放-共享”二元交互型3条主导路径。

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 prosperity 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 enhancement of common prosperity levels in this region is a consequence of synergistic factors,which can be summarized into three leading paths:ternary interweaving type of“innovation-green-openness”,multi-factor synergism type of“innovation-green-coordination-openness”,and binary interaction type of“openness-sharing”.
