Household Registration System,Dual Threshold of Non - agricultural Employment and Wage Differentials between Urban Residents and Rural Migrant Workers:Based on CHNS Data
基于2009年中国健康与营养调查数据，发现教育和经验分别是城镇居民和农民工的人力资本比较优势，教育回报率扩大城乡收入差距，户籍歧视呈倒U型特征。
Based on the China Health and Nutrition Surveys in 2009,this paper finds that education and experience are respectively comparative advantage of human capital between urban residents and migrant workers. The rates of return to education in urban residents and the rates of return to experience in migrant workers are rigid,and the former is far larger than the latter,so that education is expanding income gap between urban and rural residents.For migrant workers,technology,management and other senior occupation have high education level threshold,lower occupation existing household registration threshold,due to registration discrimination. Quantile decomposition result shows that registration discrimination is in the inverted U shape feature.Reducing household wage inequality is to advance urban and rural education equalization,strengthen migrant workers' occupation skill training and eliminate registration discrimination.
