采用可以对贫困广度、深度、强度综合测度的FGT贫困指数测算了甘肃省农村居民2001-2011年的贫困状况并用夏普里值分解法对贫困指数的变动进行了分解，测算了贫困指数变动的经济增长、收入分配和贫困线变动弹性，对基尼系数按收入来源进行了分解。研究发现甘肃省农村居民贫困范围较广、程度较深，易受贫困线变动的影响；经济增长仍然是减贫的主要动力，不断扩大的农村内部收入差距一定程度上加深了贫困的深度；工资性收入和财产性收入是收入差距不断扩大的主因，家庭经营收入和转移性收入起到改善农村内部收入不平等的作用。%Use can comprehensive measure poor breadth,depth and intensity’s FGT poverty index measured the rural residents in Gansu Province poverty in 2001-2011,and use Shapley decomposition measured the changes on poverty index.Measured the elasticity of the poverty Index on economic growth,income distribution and poverty line changes,decomposed the Gini coefficient by source of income.
