摘要
贫困与收入分配不平等是发展经济学中两个非常重要的研究方面,关于其测度方法的研究也是层出不穷。本文在对收入分布与Lorenz曲线之间等价性论证的基础上,分别采用参数与非参数两种方案来估计收入分布函数,进而给出用于测度贫困的FGT指数与测度收入分配不平等的Gini系数的参数与非参数计算方法,并将参数与非参数两类方法进行了实证上的比较。
Poverty and inequality are two important topics in development economics. Literatures on measuring methods emerge in endlessly. In the first place, we demonstrate the equivalence between income distribution and Lorenz curve. Then parametric and non-parametric methods are applied into estimating income distribution. Furthermore, parametric and non-parametric methods for computing FGT index and Gini coefficient are proposed in the paper. The two kinds of method are compared from each other through empirical analysis in the end.
