收入分配分层与不公平的统计分析
An statistical analysis of stratification and inequity in the income distribution
摘要：
对美国2001年收入分布的分析表明，收入分布至少可以由两个主成分来描述，这两个主成分服从广义Tsallis统计量，且q参数取值不同。理论计算使用气体动力学模型与分布式储蓄倾向因子和两个合奏再现的经验数据，并提供进一步的信息的分布结构，这表明了一个明确的分层。这种分层是服从不同的解释，这是分析。分配函数不随个人平均收入而变化，这意味着分配的不公平性不能通过增加总收入来改变。
英文摘要：
The analysis of the USA 2001 income distribution shows that it can be described by at least two main components, which obey the generalized Tsallis statistics with different values of the q parameter. Theoretical calculations using the gas kinetics model with a distributed saving propensity factor and two ensembles reproduce the empirical data and provide further information on the structure of the distribution, which shows a clear stratification. This stratification is amenable to different interpretations, which are analyzed. The distribution function is invariant with the average individual income, which implies that the inequity of the distribution cannot be modified by increasing the total income.
