Abstract: Based on the fact that the log household income per capita data from China Health and Nutrition Survey (CHNS) show negative skewness. I In order to meet this requirement, we propose Reverse Pareto-Lognormal composite distribution (RPLC) based on the composite distribution theory. The maximum likelihood method is used to estimate the parameters. Empirical results show this model can fit the log household income per capita well, then we derived the exact distribution of household income per capita by using changing variable method, the corresponding Lorenz curve, and the Gini coefficient. Our results show the Gini coefficients of the rural household are higher than the urban household, and reach its peak between 2007 and 2009, which is from a continued increase to a decline.
