【摘要】：本文使用CHNS家庭微觀調查數(shù)據(jù)研究發(fā)現(xiàn),我國城鄉(xiāng)居民家庭人均收入對數(shù)呈現(xiàn)明顯左偏特征。為了適應這種需要,根據(jù)組合分布函數(shù)的構造思想,首次提出使用反向帕累托-對數(shù)正態(tài)組合分布對居民收入數(shù)據(jù)進行建模,并使用極大似然估計方法對參數(shù)進行估計。然后,使用變量替換方法導出我國城鄉(xiāng)居民收入原始數(shù)據(jù)的確切分布,并在此基礎上,測算出我國城鄉(xiāng)居民收入的基尼系數(shù)。實證研究發(fā)現(xiàn),農(nóng)村居民家庭人均收入基尼系數(shù)高于城鎮(zhèn)居民,就基尼系數(shù)發(fā)展態(tài)勢而言,我國城鄉(xiāng)居民家庭收入基尼系數(shù)在2007—2009年間發(fā)生了轉變,由之前的持續(xù)增加轉為下降。
[Abstract]:In this paper, we find that the logarithm of per capita income of urban and rural households in China is obviously left-biased by using CHNS family microscopic survey data. In order to meet this need, according to the construction idea of combinatorial distribution function, It is the first time to use reverse Pareto-logarithmic normal combination distribution to model the resident income data, and to estimate the parameters by using the maximum likelihood estimation method. The exact distribution of the original income data of urban and rural residents in China is derived by using variable substitution method, and on this basis, the Gini coefficient of income of urban and rural residents in China is calculated. The Gini coefficient of per capita income of rural households is higher than that of urban residents. In terms of the development trend of Gini coefficient, the Gini coefficient of household income of urban and rural residents in China has changed from the previous continuous increase to decline from 2007 to 2009.
