摘　　要：我国经济已由高速增长阶段向高质量发展阶段转型,共享发展是高质量发展的根本目的。在构建共享发展评价指标体系基础上,定量评估2010~2020年长江经济带共享发展水平时空变化机制。结果表明:目前长江经济带共享发展水平与城市规模等级具有一致性,形成下游以沪宁杭为核心的高等集聚区且辐射带动强,中上游分别形成武汉与成都两个极值中心但辐射带动弱;2010~2020年共享发展水平总体略有提升但地域差异大,其中一类中心城市稳中有升,二类中心城市与地区中心城市提升明显,且后者内部升降差异大,一般城市降幅突出;空间上长三角地区及中游部分地区提升显著,而中游及上游一般城市降幅明显,上游与下游差距扩大;文化资源、社会保障与就业水平是差异形成的主要因素。研究结果揭示不同地市共享发展优势与短板,为制定长江经济带高质量发展差异化举措提供依据。China's economy has shifted from high-speed growth to high-quality development,and the shared development has become the fundamental objective.Based on the evaluation index system of prefectural units and shared development,this study quantitatively evaluates the differences and changes in shared development levels in the Yangtze River Economic Belt from 2010 to 2020.The results show that:the shared development levels of different scale grade cities decreased in order.The downstream area forms a high agglomeration area with Shanghai,Nanjing,and Hangzhou as the core,with strong radiation-driven effects.In the upstream and midstream areas,Wuhan and Chengdu form two extreme value centers,but with weak radiation-driven effects.From 2010 to 2020,the first class of central cities is steadily increasing in general,the second class of central cities and regional central cities are significantly elevated,while the regional central cities differ between uplift and subsidence,and other cities are lowering significantly.The Yangtze River Delta region and part of the midstream areas are significantly growing,and other cities of the upstream and midstream areas are significant decreasing.The gap between downstream and upstream is widening.The difference in cultural resources is the most obvious factor,followed by the fiscal expenditure on social security and employment.The economically developed areas enjoy a high level of shared development in compulsory education,culture,social security,and employment,while the economically backward areas have the advantages in health and medical community and environmental greening.The results show the advantages and disadvantages of the sharing development level of different scale-grade cities,and provide a basis for the formulation of differentiated policies for the high-quality development of the Yangtze River Economic Belt.
