| Abstract: | 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. |
