摘要
本文基于共同富裕视域,利用我国2002—2019年的省级面板数据,分析人口老龄化与社会保障支出对城乡收入差距的影响。研究发现:(1)人口老龄化会显著扩大城乡收入差距,阻碍了实现共同富裕的进程,社会保障支出由于城镇偏向性也扩大了城乡收入差距,对共同富裕存在“逆推效应”,但二者交互作用则对城乡收入差距存在抑制效应,即社会保障支出能够有效削弱人口老龄化对城乡收入差距的扩大效应,缓解人口老龄化对共同富裕的压力;(2)异质性检验表明,社会保障支出抑制人口老龄化对城乡收入差距的扩大效应仅对人口老龄化程度较高地区、东部和西部地区显著;(3)从支出结构看,社会救济支出、社会福利支出以及社会保险支出均显著削弱了人口老龄化对城乡收入差距的扩大效应。因此政府部门应通过改善人口结构、优化社会保障支出水平和结构等方式缩小城乡收入差距,切实有效推进共同富裕。
From on the perspective of common prosperity,this paper empirically studies the impact of population aging and social security expenditure on urban-rural income gap with selected panel data from 2002 to 2019.The results show that:(1)both population aging and social security expenditure significantly widen urban-rural income gap,bringing great pressure to common prosperity.However,the interaction of population aging and social security expenditure can restrain urban-rural income gap.(2)According to heterogeneity test results,social security expenditure inhibits the widening effect of population aging on the widening income gap between urban and rural areas,which is only significant for the eastern and western regions,and regions with a high degree of population aging.(3)From the perspective of expenditure structure,social assistance expenditure,social welfare expenditure and social insurance expenditure have significantly weakened the pressure of population aging on the income gap between urban and rural areas.Therefore,government departments should narrow urban-rural income gap by optimizing the level and structure of population and social security expenditure,and effectively promote common prosperity.
