【摘要】 社会保险是我国社会保障体系的核心内容，它对促进社会更加稳定、公平、进步以及推动区域高质量发展作用重大。本文采用熵值法、空间自相关、地理探测器等方法分析2012—2018年长江经济带社会保险水平的时空演变及影响因素。结果表明：(1)长江经济带社会保险水平整体快速增长，省际间的相对差异在逐渐缩小，社会保险水平东部>西部>中部；(2)研究期内长江经济带大多数省份社会保险水平相对偏低，整体上具有显著的集聚特征，热点区和冷点区表现出较稳定的空间演变特征；(3)长江经济带社会保险水平空间分异特征受多种因素影响，城镇居民人均可支配收入、城镇单位就业人员工资总额、人均GDP是其主导因素。未来长江经济带应统筹发展社会保险制度，逐渐缩小东中西部社会保险水平的差距。更多还原

【Abstract】 Social insurance is the core content of China’s social security system, it plays an important role in promoting social stability, equity, progress and promoting regional high-quality development.By using the methods of entropy, spatial autocorrelation and geographic detector, this paper analyzes the spatial-temporal evolution and influencing factors of social insurance level in the Yangtze River Economic Belt from 2012 to 2018. The results are as follows:(1) The overall social insurance level in the Yangtze River Economic Belt is growing rapidly, the relative differences between provinces are gradually decreasing, and the social insurance level is east > west > central;(2) Most of the provinces in the Yangtze River Economic Belt have relatively low social insurance levels during the study period, with significant clustering characteristics overall, and hotspot and coldspot areas show more stable spatial evolution characteristics;(3) The spatial divergence characteristics of the social insurance level in the Yangtze River Economic Belt are influenced by various factors, with urban residents’ per capita disposable income, total wages of urban unit employees and per capita GDP being the leading factors.In the future, the Yangtze River Economic Belt should develop the social insurance system as a whole and gradually narrow the gap between the eastern, central and western social insurance levels.更多还原
