与基尼系数相关联的3个重要参数

Three Important Parameters Related with Gini Coefficient

利用中值定理以及曲线的最小二乘拟合原理,首次引入并介绍了与基尼系数相关的3个重要概念:基尼系数点,收入分界点,理想收入分配曲线.其中每一个概念都依赖于一个重要参数,3个参数反映了基尼系数的大小、变化趋势以及理想收入分配曲线的数量特征.

Using mean value theorem and the principle of least squares curve fitting , this thesis introduces three important concepts related with Gini Coefficient for the first time： Gini Coefficient point, boundary point of income distribution and ideal income distribution curve. Each of the three concepts depends on one important parameter and the three parameters vividly reflect the dimension and variation tendency of Gini Coefficient and the quantative attribute of ideal income distribution curve is reported.
