摘　　要：文章运用中国健康与营养调查数据(CHNS)中2000-2015年人口数据作为考察对象,将可分解测度贫困指数(FGT)基于农村贫困线、城镇贫困线以及整体贫困线分解为组内与组间两个部分。结果表明,三种贫困指标的农村组内、城镇组内以及农村与城镇的组间贫困趋势基本一致,农村与城镇的组间贫困发生率、组间贫困距指数和组间贫困距平方指数呈现下降趋势,农村组内贫困发生率、贫困缺口率,以及贫困距平方指数由对增贫的弱化作用转为对增贫的正向贡献。This paper uses the demographic data from 2000 to 2015 from the China Health and Nutrition Survey(CHNS) as the object of study, and is based on the rural poverty line, urban poverty line and overall poverty line to decompose the resolvable measure poverty index(FGT) into within-group poverty and intergroup poverty. The research shows that the poverty index within rural groups, urban groups, and between rural and urban groups presents basically the same trends, that the incidence of intergroup poverty in rural and urban areas, intergroup poverty distance index, and the square index of poverty distance between groups shows a downward trend, and that the incidence of poverty, the poverty gap rate, and the poverty distance squared index in the rural group change from the weakening of poverty increase to the positive contribution to poverty increase.
