【摘要】：收入不平等是我国经济增长过程中的突出现象,而人口老龄化对收入不平等有着重要影响。利用全域莫兰指数(Moran’s I)和局域空间自相关的LISA聚集图,对我国各省域收入不平等的空间相关性进行检验,并运用1998—2014年省级面板数据构建空间滞后模型和空间误差模型,探索老龄化影响收入不平等的作用机制,结果表明:我国各省域居民收入不平等具有显著的空间正相关性,即收入差距较大(小)的省域倾向于与其他收入差距较大(小)的省域相邻;老龄化会显著地拉大收入不平等,并且这种影响主要来自顶部老龄化,因为不同年龄群体内的收入不平等是随着年龄增加而扩大的。
[Abstract]:Income inequality is a prominent phenomenon in the process of economic growth in China, and the aging of population has an important impact on income inequality. The spatial correlation of income inequality in different provinces of China is tested by using Morans I) and local spatial autocorrelation (LISA), and spatial lag model and spatial error model are constructed by using provincial panel data from 1998 to 2014. This paper explores the mechanism of aging affecting income inequality. The results show that the income inequality of residents in different provinces in China has significant spatial positive correlation. That is, provinces with large (small) income gaps tend to be adjacent to other provinces with large (small) income gaps; ageing significantly increases income inequality, and this effect comes mainly from the ageing of the top. Because income inequality within different age groups increases with age.
