将收入差距分为农村内部收入差距、城乡相对收入差距和城乡绝对收入差距，使用CFPS2010—2018年面板数据研究三类收入差距对农村居民消费的影响，结果表明：三类收入差距的系数均显著为负，2010—2018年分别降低农村居民2.988%、-0.772%、3.006%的消费，城乡绝对收入差距的负向影响最大；农村内部收入差距和城乡相对收入差距的负向影响与户主年龄之间是非线性关系，而城乡绝对收入差距的负向影响与户主年龄之间是斜率为负的拟线性关系，农村内部收入差距的负向影响在地区间的排序为西部地区>东部地区>中部地区；而城乡收入差距的负向影响排序相反；农村内部收入差距显著降低其他类消费、生存型消费、福利型消费和房贷型消费，而城乡收入差距主要抑制农村居民其他类消费和发展型消费，整体而言收入差距主要通过降低其他类消费进而负向影响总消费。

The income gap is divided into rural internal income gap, urban-rural relative income gap and urban-rural absolute income gap. Findings of using the panel data of CFPS from 2010 to 2018 to study the impact of these three income gaps on rural residents' consumption show that the coefficients of the three income gaps are significantly negative, reducing rural residents' consumption by 2.988%,-0.772%,3.006% respectively from 2010 to 2018, with the negative impact of urban-rural absolute income gap being the largest A nonlinear relationship exists in the negative effects of the rural internal income gap and the urban-rurual relative income gap and the age of the head of a family while a quasi-linear relationship with a negative slope can be found in the negative effects of the urban-rural absolute income gap and the age of the head of a family. The negative impact of rural internal income gap in regions is in the order of western region > eastern region > central region while that of urban and rural income gap is in the reversed order The rural internal income gap significantly reduces other types of consumption, subsistence consumption, welfare consumption and mortgage consumption whereas the urban-rural income gap mainly inhibits rural residents’ other types of consumption and developmental consumption. In general, the income gap mainly affects the total consumption negatively by reducing other types of consumption.
