摘　　要：分析了收入达不到洛伦兹函数均值的人口比例,以及这个比例和基尼系数的关系,探讨它所反映的贫富差距的信息,并通过模拟洛伦兹函数确定了参数取值与基尼系数在一定范围内的关系。The ratio of the population whose income less than average of lorenz function and the relationship between the proportion and Gini coefficient were analyzed. The gap of income disparity was discussed. The relationship of parameter selection and the Gini coefficient within a certain range was determined by simulating Lorenz function.

关 键 词：收入差距 洛伦兹均值 基尼系数
