This paper firstly constructs an inclusive financial development index measurement system in rural in Guangxi. Based on the measurement results, cluster analysis of 40 counties in Guangxi in 2013-2017 is operated; then test the increase effect of the income of inclusive financial development. Considering the differences in farmers" income levels in different regions, this paper constructs a quantile regression model for further research. The results show that the development of rural inclusive finance in Guangxi has a positive effect on farmers" income growth, but for farmers with lower income levels, the development of inclusive finance has inhibited income growth. This paper proposes to promote the development of rural inclusive financial cooperation between counties by optimizing the rural inclusive financial development environment, giving play to the government"s policy guidance and macroeconomic regulation and control, and effectively improving the income-increasing effect of rural inclusive financial development.
