As an important part of the rural revitalization strategy, fiscal funds related to agriculture have a certain impact on farmers' income. This paper selects the panel data of 14 counties in the Wanjiang urban belt of Anhui Province from 2014 to 2019 to construct a double difference model to explore the impact of the integration of financial agriculture-related funds on increasing the income of rural residents. The analysis results show that the financial agriculture-related funds have a significant impact on farmers' income increase, and the growth rate is about 1.27 percentage points compared with the control group. Based on this, this article proposes to continue to increase the total fiscal expenditure for agriculture, improve the integrated management mechanism of fiscal agriculture-related funds, strengthen the supervision of the use of funds, consolidate the effect of increasing farmers' income, and help the revitalization and development of rural areas.
