With the deep integration of the digital economy and agricultural development, agricultural digital transformation promotes agricultural production, and industrial upgrading and broadens sales channels to achieve the strategic goal of rural revitalization in China. To explore whether agricultural digitization can help farmers increase their income and what path can be achieved, this study is based on the theoretical framework of rural revitalization theory and digitization. Through a questionnaire survey of 1500 farmers in Hubei Province, the impact mechanism of agricultural digitization transformation on farmers’ income is empirically studied. The empirical results show that the digital transformation of agriculture can promote the increase in farmers’ income, and promote the increase in farmers’ income by improving production efficiency, broadening sales channels, and promoting the upgrading of agricultural structure. At the same time, both production efficiency and sales channels form a chain double intermediary path with the upgrading of agricultural structure. Under the background of rural revitalization, this study provides theoretical references and guidance for further promoting agricultural digital transformation to increase farmers’ income. The marginal contribution of this study is to construct a theoretical model of agricultural digitization to promote farmers’ income increase, which has important theoretical reference and guiding significance for guiding the development direction of agricultural digitization and promoting farmers’ income increase.
