政府在对贫困人口实施收入救助时,通常以追求目标群体贫困最小化为出发点。同时,政府常借助于贫困指数来评估贫困和反贫困政策效果。对收入相异的贫困人口而言,实际能否得到救助很大程度上取决于政府的评估方法和约束条件。基于此,探讨了在不同约束条件下,贫困测度方法与反贫困目标瞄准之间的关系。结果表明,从效率和公平的角度看,我国应采用Fα(0<α<1)指数作为贫困评估方法,以实现Type-pr类反贫困政策。
The government usually pursue minimization of poverty when the government help the poverty people.At the same time,the government use the poverty index to evaluate the poverty and anti-poverty policy effect.Based on this,the paper analysis the relationship between the method of poverty measurement and the targeting of anti-poverty goals.As result,we suggest that China should adopt Foster poverty index(0<α<1) as the poverty evaluation tools.
