【摘要】 对于任意给定的收入分布建立了反映收入分配差异的基尼系数模型,并对模型中影响基尼系数的因素进行分析,得出了比较丰富的结果;同时证明了劳动力在2种收入状态之间的转移将使基尼系数呈现倒U形曲线形式.讨论了在教育扩展过程中如果伴随劳动力收入状态的转移,那么这种教育扩展对收入差异的影响必然会使基尼系数经历先扩大后缩小的变化过程.更多还原

【Abstract】 For any given income distribution, a Gini coefficient model that can show the disparity of income distribution is presented. The relevant factors which influence this disparity are discussed. At the same time, it concludes that the Gini coefficient curve will be inverse-U shaped if labors’ income increases from one level to a higher level. If more education can make a labor richer, it is shown that with education expansion, the disparity will be large at first and then small.更多还原
