Abstract: Since the reform and opening-up, income gap of the western rural is growing. By using the data of western provinces in China from CHNS in the period 1989~2011, this paper studies income mobility structural characteristics and influencing factors of western rural resident. We use income transformation matrix to analyze the dynamic evolution of different income classes. The results show that, the phenomenon of rigidity between the poor and rich is serious and the middle classes tend to be brittle. Logistical regression analysis shows that income structure, expenditure structure and the occupational characteristics play significant roles in the income mobility. It is imperative to improve the income mobility structure of western rural residents from the system.
