摘要: 构建一类新的拟合效果更好的洛伦兹曲线模型，并针对1977年美国收入分配分组数据进行数值实验。实验结果表明，该类模型拟合效果较好。
Abstract: A new kind of Lorenz curve model with better fitting effect is constructed, and numerical experiments are carried out on the grouped data of American income distribution in 1977. The experimental results show that this kind of model has better fitting effect.
