摘　　要：居民收入基尼系数作为刻画居民收入不平等的指标,是政策制订和相关学术研究的重要基础资料。国家统计局、世界银行等机构和不同学者对1978年以来的中国总体收入基尼系数进行了各自测算,但由于基础数据、假设条件、测算方法的差异,各版本的测算年份参差不齐,数据结果差异显著,不利于后续使用。文章将不同版本的基尼系数测算结果视为对理论基尼系数的观测样本,在合理假设下推论得到填充不同版本基尼系数缺失数据的估计方法,并以国家统计局基尼系数为例,对1978—2020年数据进行了填充估计,为后续研究提供了统一可比的中国总体收入基尼系数时间序列,同时也为类似问题的解决提供了方法借鉴。The Gini coefficient of residents’income,as an indicator to portray the inequality of residents’income,is an important basic information for policy formulation and related academic researches.The National Bureau of Statistics(NBS),the World Bank,and some scholars have made their own estimations of China’s overall income Gini coefficient since 1978,but due to differences in underlying data,assumptions and methodologies,the years of measurement and results vary from version to version significantly,which is not conducive to subsequent studies.This paper,equally treating existing Gini estimations as a sample of observations of the theoretic Gini coefficient,obtains the methodology of filling missing data of Gini coefficient of different lectures under theoretically reasonable propositions,and fills the missing data by NBS,taken as an example,from 1978 to 2020,providing a unified and comparable time series of the overall Chinese income Gini coefficient for the studies concerned,and as well,a referable solution for the problem in the same category.
