摘　　要：旨在考察一个较长的时间序列内农村低收入人口贫困状况的动态变化,探明经济增长和收入分配等宏观层面影响因素与贫困指数之间的定量关系与内在联系。基于GQ模型和(模型,选取具备可分解性的FGT指数,采用1990—2006年福建省农村居民收入分组面板数据,分别运用4条低收入标准线对低收入群体的H指数、PG指数、SPG指数和贫困弹性进行模拟。实证结果表明,福建省的经济增长有效减少了绝对低收入人口数量,而收入分配差距的扩大却降低了低收入群体的潜在福利,从而影响农村相对贫困的减少效果。This paper aims to study the dynamic changes in poverty of China＇s rural low-income group in long time series to explore quantitative relationships and internal relations between economic growth as well as income distribution and poverty index. Based on the General Quadratic model and Beta model of Lorenz curve,it uses the decomposable FGT index and the grouped Panel Data about income of rural residents in Fujian province from 1990 to 2006, and respectively simulates H, PG and SPG index as well as poverty elasticity of low-income group based on four towincome standard lines. The empirical results show that economic growth effectively reduces the absolute amount of low-income population, but the enlarged gap of income distribution decreases their potential benefits,which affects the relative rural poverty reduction.
