摘要
本文基于2001-2020年我国省级面板数据,以经济发展、社会保障覆盖面、社会保障待遇和社会保障支出结构四个因素为门槛变量,揭示社会保障和城乡收入差距之间的非线性关系。结果表明:社会保障对城乡收入差距的影响具有经济发展和社会保障制度依赖性,以经济发展、社会保障覆盖面和社会保障待遇为门槛,社会保障对城乡收入差距的影响均呈现从扩大到缩小的倒“U”或近似倒“U”型转变;以社会保障支出结构为门槛,社会保障缩小城乡收入差距的效应跨越门槛后更大,表现为门槛加强特征。为此,从持续推动经济高质量发展、提高社会保障实际参保率、统筹城乡社会保障待遇、优化社会保障项目结构等方面提出了相关对策建议,以期为更好地发挥社会保障缩小城乡收入差距的作用提供有益的参考。
Based on our country's provincial panel data from 2001 to 2020,this paper tries to reveal the nonlinear relationship between social security and urban-rural income gap by using economic development,social security coverage,social security benefits and social security expenditure structure as threshold variables.The results show that the influence of social security on the urban-rural income gap is dependent on economic development and social security system.Taking economic development,social security coverage and social security benefit as the threshold,the influence of social security on the urban-rural income gap shows an inverted“U”or approximately inverted“U”shape of changing from expanding to narrowing;Taking social security expenditure structure as the threshold,the effect of social security in reducing the income gap between urban and rural areas is greater after crossing the threshold,which is characterized by threshold strengthening.Therefore,the paper discusses relevant suggestions in terms of continuously promoting high-quality economic development,increasing the actual participation rate of social security,coordinating urban and rural social security benefits,and optimizing the structure of social security projects,in order to make social security narrow the income gap between urban and rural areas better.
