社会财富分配保持一定的均衡度,是一个国家维持政治经济稳定局面的必要前提。我国当前深化改革,发展经济,建设高度发达的社会主义物质文明和精神文明,对社会财富分配的均衡问题,不容忽视。国外对社会财富分配均衡度的统计和数量分析工具主要是洛伦茨曲线(LorenzCurve)和基尼系数(Gini Coefficient)。洛伦茨曲线因保罗·洛伦茨(PaulLorenz)首次提出而得名。从统计学角度看,洛伦茨曲线是一条特殊的累计频数曲线。一般的累计频数曲线的横轴表示所研究的变量(以绝对数形式出现),纵轴表示该
The distribution of social wealth to maintain a certain degree of balance is a necessary prerequisite for a country to maintain a stable political and economic situation. At present, China can not ignore the current situation of deepening the reform, developing the economy, building a highly-developed socialist material and spiritual civilization and balancing the distribution of social wealth. The statistical and quantitative tools used abroad to balance the distribution of social wealth are mainly the Lorenz Curve and the Gini Coefficient. The Lorenz curve is named after Paul Lorenz first proposed. From a statistical point of view, Lorenz curve is a special cumulative frequency curve. The horizontal axis of a general cumulative frequency curve represents the variable under study (in absolute terms), and the vertical axis represents the
