Abstract: Increasing farmers' income not only affects the progress of the rural revitalization strategy, but also affects the realization of common prosperity. Based on the construction of the mechanism model and making use of the data of“China Land Economy Survey”and the econometric method, this paper empirically tests the impact of rural digital economy development on farmers' income. The results show that the development of rural digital economy can significantly improve the income level of farmers. The mechanism analysis shows that the development of rural digital economy has promoted the development of rural non-agricultural industries and improved the human capital and social capital of the farmer households, thus promoting the increase of farmers' income. The development of digital economy in rural areas has not achieved inclusive growth in farmers' income, and the promoting effect on the income of high-income households is greater than that on the low-income households. The grouping regression results show that the development of rural digital economy has a greater impact on the wage income of rural households than the asset income and agricultural operation income, and this impact is more obvious on the income increase of middle-aged households and the households in the economically developed regions. The above research conclusions provide a new research perspective for evaluating the impact of digital economy on farmers' income. It is also suggested to strengthen policy support for the areas with relatively backward digital infrastructure, improve the operating system for the construction of rural digital economy and the publicizing and training system for the rural digital technology, so as to ensure the balanced development of digital economy between the rural and urban areas. We should let digital economy play a better role in narrowing the gap between urban and rural areas and in promoting the realization of common prosperity.
