Abstract: Based on 6 937 residents' questionnaires from 31 provinces, this paper applied Mincer income model and Oaxaca-Ransom decomposition method to analyze empirically the main influencing factors of urbanrural income gap in China. The results showed that the income gap between urban and rural residents of China was large, and Gini coefficient had exceeded the warning line. The personal and family characteristics of household, human capital, regional differences and differences between urban and rural areas had significant impacts on the household income. For the urban-rural income gap, the contribution rate of education level differences was the largest one, the contribution rates of urban-rural dual structure differences and the basic personal and family characteristics differences were larger, and the contribution rate of regional differences was in minimum. Some policy recommendations to narrow the urban-rural income gap were provided in this paper.
