Exploring the impacts and the mechanism of digital inclusive finance on farmers’ income growth is of great significance to promote rural financial development, to increase farmers’ income, and to share the dividend of economic development. Based on a panel data from the China Household Tracking Survey (CFPS) and the Peking University Digital Inclusive Finance Index in 2014, 2016 and 2018, this paper analyzed the impacts and the mechanism of digital inclusive finance on farmers’ income growth by the intermediary effect model. Results show that the development of digital inclusive finance in rural areas is unbalanced and there is a large gap among farmers with different income levels. This research also finds that 48.0% of farmers’ non-agricultural employment level is 0, indicating that promoting non-agricultural transfer of rural labor force is still a challenging task. Both digital inclusive finance and non-agricultural employment are positively promoting the growth of farmers’ income. Non-agricultural employment level is an important channel for digital inclusive finance to affect farmers’ income, and the intermediary effect accounts for 3.507%. In addition, compared with farmers with more wealth, the income increasing effect of digital inclusive finance on farmers with less wealth is more obvious. Therefore, to increase farmers’ income, this paper suggests: improving digital construction in rural areas, providing accurate digital financial products for different farmers, encouraging and guiding the use of digital financial products, promoting balanced development of digital inclusive finance, and improving non-agricultural employment level of farmers.
