Study on the Lorenz Curve and the Gini Coefficient
作者运用数理统计的手段，分析了在经济学中广为应用的描述性曲线-洛伦茨曲线y=L(t)的数理实质，给出其积分表达式，L(t)=(1/Eξ)∫t0F-1(u)du，并在此基础上讨论某些分布的吉尼系数与标准差系数的关系，同时给出一个讨论一般分布函数的吉尼系数的途径：将分布函数展成泰勒级数。
By using methods of mathematical statistics, the essence of Lorenz curve y=L(t),a kind of descriptive curve widely used in economics, was analysed; L(t)=(1/Eξ)∫t0F-1(u)du. Based on this result, the relationship between the Gini coefficient of some distribution and the standard deviation coefficient was discussed, also a method for discussing for general distributions function the Gini coefficient was given, i.e., to the distribution function into a Taylor series.
