| 中文摘要: |
| 研究目标：在生产发展变迁的大视野下重新审视中国改革开放以来的收入不平等演变。研究方法：立足于生产与分配相联系的理论观点，以基尼系数的群组分解公式为基础，推导并测算中国收入不平等可能性边界（IPF）和不平等提取率（IER）。研究发现：（1）1978~2017年间，随着社会生产发展水平的不断提高，中国收入不平等可能性边界持续扩张，最大可行基尼系数从0.2281提升至0.8446。（2）同期中国收入不平等提取率总体呈现下降趋势，从123%下降到55%。其中1978年~20世纪80年代中期快速大幅下降；20世纪80年代中期~2012年前后比较稳定；2012年党的十八大以后呈进一步下降现象。目前中国仍有55%的最大可行不平等转化为实际不平等。研究创新：将分配与生产相联系的观点直接嵌入不平等经验测度中，弥补传统的不平等测度指标忽视生产发展水平及其变迁的缺陷。研究价值：初步解释“改革开放以来中国经济社会对收入差距扩大具有一定承受力”之谜，并为新时期进一步处理好经济发展和收入分配关系提供了直接的经验证据。 |

| Research Objectives:To re-examine the evolution of income inequality since China's reform and opening up in the broad vision of production development changes. Research Methods:Based on the theory that production and distribution are unified, this paper deduces and calculates China's income Inequality Possibility Frontier (IPF) and Inequality Extraction Ratio (IER) through the group decomposition formula of Gini coefficient. Research Findings:(1) 1978~2017, with the improvement of social production level, China's IPF continued to expand, and the maximum feasible Gini coefficient increased from 0.2281 to 0.8446. (2) In the same period, China's IER generally shows a downward trend, from 123% to 55%. Among them, from 1978 to the mid-1980s, there was a rapid and significant decline. The period from mid-1980s to 2012 was relatively stable. After the 18th National Congress of Chinese Communist Party in 2012, it showed a further decline. China still has 55% of the maximum feasible inequality translated into real inequality. Research Innovations:The viewpoint of the unification of distribution and production is directly embedded into the empirical inequality measure to make up the defect that the traditional inequality measure ignores the level of production development and its changes. Research Value:Preliminarily explaining the mystery that “China's economy and society have a certain bearing on the widening income gap since the reform and opening up”, and providing direct empirical evidence for further handling the relationship between economic development and income distribution in the new period. |
