摘要
从共同富裕的视角出发,基于2001—2021年省级面板数据,检验社会保障支出对城乡收入差距的非线性影响。结果表明:社会保障支出和城乡收入差距之间呈现先扩大后缩小的倒U型关系,城乡居民社会保障待遇“共享”程度在其中起到中介传导作用。进一步分地区考察,发现这一倒U型关系依然成立,且中部和西部地区倒U型曲线更宽,社会保障支出的边际影响效应更大,曲线拐点处对应的社会保障支出更多。为此,切实缩小城乡收入分配差距不仅要扭转社会保障支出中存在的城镇偏向,不断提高城乡居民社会保障待遇“共享”程度,而且要持续增加社会保障支出,增强社会保障“富裕”程度,此外要注重调整社会保障支出的区域偏向,加大对中西部地区社会保障投入。
From the perspective of common prosperity,this study re-examines the non-linear impact of social security expenditure on the urban-rural income gap based on the provincial panel data from 2001-2021.The results show that there is an inverted U-shaped relationship,first expanding then shrinking,between the social security expenditure and the urban-rural income gap,in which the degree of "sharing"of the social security benefits between urban and rural residents plays a mediating role.Further investigation in different regions reveals that this inverted U-shaped relationship also exists,that the inverted U-shaped curve of the central and western regions is wider,that the marginal impact effect of social security spending is greater,and that the social security expenditure at the inflection point of the curve is even more.Therefore,in order to effectively narrow the urban-rural income gap,it is necessary not only to reverse the urban bias existing in the social security expenditureand improve the degree of"sharing"of social security benefits between urban and rural residents,but also to continuously increase social security expenditure to improve the degree of "prosperity"of social security,as well as to pay attention to the adjustment of the regional bias of social security expenditure and increase the social security input in the central and western regions.
