财政支出和人口老龄化对城乡居民收入差距影响研究

Research On the Income Gap between Urban and rural residents in Terms of Fiscal Expenditureand Population Aging

以我国2005-2015年31个省(市、自治区)面板数据为样本,分析了财政支出和人口老龄化对城乡居民收入差距的影响,并考察了人口老龄化背景下财政支出与城乡居民收入差距之间的关系差异。实证结果表明:全国层面上政府财政支出会缩小城乡居民收入差距,而人口老龄化会扩大城乡居民收入差距。在人口老龄化背景下财政支出反而会扩大城乡居民收入差距,但人口老龄化程度的加深也会削弱这一扩大效应。该研究不仅丰富和发展了财政支出作用于城乡居民收入差距的机理,而且为老龄化问题的研究提供了有价值的视角。

Taking the panel data of 31 provinces（municipalities and autonomousregions）in China for 2005-2015 years as samples,the influence of fiscalexpenditure and population aging on the income gap between urban and ruralresidents was analyzed,and the difference between the fiscal expenditure andthe income gap between urban and rural residents was investigated.In thecontext of population aging,fiscal expenditure will expand the income gapbetween urban and rural residents,but the deepening of the aging of the populationwill also weaken this expansion effect.This study not only enriches anddevelops the mechanism of the fiscal expenditure on the income gap betweenurban and rural residents,but also provides a valuable perspective for theresearch on the problem of aging.
