基于非匿名性的亲贫困增长测度

Measuring Pro-poor Growth Based on Non-anonymity

通过对匿名性与非匿名性情形下贫困发生曲线的实证研究,指出在匿名性情形下贫困发生率曲线可能高估或低估不同收入群体的实际收入增长情况,其主要原因在于匿名性情形下相同位序上的两期收入表示的不是同一个体。由于不能剔除返贫效应,在贫困人口下降时及匿名性情形下会低估实际的减贫效应。对浙江减贫效应分解结果显示,匿名性和非匿名性情况下收入分配效应对减贫的影响有很大差异甚至是反向的。对于反贫困问题而言,更应关注持续性贫困,并且在分解减贫效应时必须剔除返贫效应。

Poverty incidence curve is likely to over-or underestimate the real revenue growth of different income groups under anonymity circumstances,this mainly due to the same rank on the two-period incomes is not point to the same individual in the case of anonymity.Without remove the effect of back into poverty,when poor population declines,it may underestimate the poverty-reducing effects in the case of anonymity.Decomposition of poverty-reducing effects of Zhejiang Province shows there are very different in the impacts of income distribution effect.For anti-poverty issues,it should take more attention on sustained poverty,and effect of back into poverty must be removed in the decomposition of povertyreducing effects.
