| 摘 要： | 中等收入人口的确定对于分析一个社会的经济发展,稳定性具有重要的意义.洛伦兹曲线是一种分析中等收入的经典工具.本文提出一种具有更高拟合精度的洛伦兹曲线模型.并基于其几何特征,考虑社会的贫富程度与贫富分化因素,建立了收入空间法与人口空间法的优化模型.

A New Approach Based on Geometrical Characteristics of the Loren Curve to Measure the Middle Class |
| |
| Abstract: | Defining the middle class is of enormous importance to analysis of economic and stability of a society.Particually,Lorenz Curve is a useful method is terms of that.To improve its precision,a modified Lorenz Curve model is presented.Based on geometrical characteristics of the modified Lorenz Curve,a new approach to modify "income space" as well as "population space" to measure the middle class is established,taking the development of economy and the rich and poor differentiation into consideration. |
