摘要
分析了基尼（Gini）系数不能准确地反映洛仑兹（Lorenz）曲线的形状和收入分配的不公平程度这一问题，并在此基础上引进了三个参数Vσ、和Γ（λ）．Gini系数和这三个参数一起就能很好地刻划Lorenz曲线的形状，从而能较好地反映出收入分配的不公平程度．本文还给出了Vσ、和Γ（λ）的简便实用的估算公式和具体的例子．
The problem, which Gini cocfficient cannt reflect the shape of lorenz curve and the faimessof income distribution exactly, is inveshgated and three coefficient are indriuced, Vσ、λ and Γ(λ). Gini co-efficient, along with the three coefficient, is capable of ouilining the shape of Lorenz cun;e, reflecting the fair-ness of income distribution. Moreover, there are convenient and practical formulas to estiInate Vσ、λ and Γ(λ) as well as examle.
