摘要


利用洛仑兹曲线的特性,构造出新模型,证明了该模型满足洛伦兹曲线条件.并用实际数据进行验证,找出了五种洛伦兹曲线模型与之对比,发现新模型拟合效果非常显著,这一模型为更好地监控居民收入分配格局提供了较好的理论依据,具有一定的实际意义. A new model, which is proved to satisfy the conditions of the Lorenz curve, is constructed according to the characteristics of the Lorentz curve. Then, some data are used to compare this new model with other five models of the Lorentz curve and a very good fitting result is obtained from this new model, which provides a better theoretical basis for monitoring the pattern of the citizens income distribution and has some practical significance.
