【摘要】：收入分配的不平等测度往往基于截面的测度,衡量的是某个时点的静态的收入分配差距。本文关注的是收入分配差距是否能够在长期改善或者不同收入阶层是否能够跳跃至其它收入阶层,于是需要研究居民收入流动性。本文采用1989~2009年中国营养健康调查数据,分别利用一阶段指数和两阶段指数衡量了20年间收入流动性的状况,发现之前学者对于收入转移矩阵调整中可能存在的问题以及分解流动性时的主观权重问题,并且进行了相应的改进,得出了不同的结论。此外,本文利用K-C方程和收入转移矩阵计算了二阶和更高阶数的转移矩阵,提出了用矩阵收敛速度解决时间依赖型转移矩阵中测度期间选择的主观性问题的方法,并测算出中国居民收入流动中结构性因素的调整周期在12.25年左右,Fields指数的计算结果验证了这个结论。
[Abstract]:The inequality measure of income distribution is usually based on the measure of cross section, which measures the static income distribution gap at a certain point. This paper focuses on whether the income distribution gap can be improved in the long term or whether different income groups can jump to other income groups, so we need to study the income mobility of residents. The data of China Nutrition Health Survey from 1989 to 2009 were used to measure the income mobility in the past 20 years by using the one-stage index and two-stage index, respectively. It is found that the problems that may exist in the adjustment of the income transfer matrix and the subjective weight problem in the decomposition of liquidity are studied before, and the corresponding improvements are made, and different conclusions are drawn. In addition, by using K-C equation and income transfer matrix, the transfer matrix of second order and higher order numbers is calculated, and a method of solving the subjective problem of time dependent transition matrix during measurement is proposed by using the convergence speed of matrix. It is estimated that the adjustment period of structural factors in the income flow of Chinese residents is about 12.25 years. The calculation results of Fields Index verify this conclusion.
