Abstract: Based on the CGSS data, this paper uses the quantile regression method to estimate and decompose the wage differentials of formal employment and informal employment. The results show that the wage of formal employment is signally higher than that of informal employment, and on the three representative quantiles, the rate of return to education is higher in formal employment than in informal employment. At the same time, in both formal and informal employment, the rate of return to education has a tendency to rise first and then fall with wage quantile changing from low to high. Compared with formal employment, the gender discrimination in informal employment is more serious and becomes more and more serious with wage quantile rising from low to high. Wage decomposition shows that market discrimination is significantly higher than feature differences.
