Exploring whether digital inclusive finance can increase people's income is vital for realizing common prosperity.Based on the expanded endogenous economic growth model,this paper constructs a theoretical framework for the impact of digital inclusive finance on farmers'income and empirically studies the mechanism and spatial spillover effects using the data of counties in the Yangtze River Economic Belt from 2014 to 2020. The findings show that digital inclusive finance can increase farmers'income.Compared with the degree of digitization,the breadth of coverage and depth of use are more capable of promoting farmers'income.Agricultural technology progress,rural human capital accumulation,and farmers'physical capital accumulation are transmission paths for digital inclusive finance to increase farmers'income.Furthermore,digital inclusive finance has the strongest effect on farmers'income in the lower reaches of the Yangtze River Economic Belt,followed by the middle and upper reaches.Moreover,digital inclusive finance has a stronger effect on farmers'income for counties with high-income levels,large population size,and large cultivated land.From the spatial perspective,digital inclusive finance has a significant spatial spillover effect,with an obvious spillover boundary.Within 50 km,it can effectively increase farmers'income in neighboring areas,but there is a suppression effect in the range of 50～250 km. The contributions of this paper are mainly reflected in the following aspects.First,based on the extended endogenous economic growth model,digital inclusive finance and farmers'income increase are included in the same theoretical framework,providing a new research perspective.Second,566 counties in the Yangtze River Economic Belt are selected to mitigate the bias of the estimation results caused by using provincial or municipal areas as the research sample.Third,this paper examines the heterogeneous impact of region,income,population size and land size from multiple perspectives,and systematically identifies the target of digital inclusive finance,enriching the relevant research.Fourth,the spatial correlation and endogeneity issues are considered based on the theories of spillover effect and clustering shadow,and a county spatial weight matrix is constructed to use the spatial Durbin model(SDM)to investigate the spatial effect of digital inclusive finance on farmers'income and to further identify the spillover boundary. The findings outline the relationship between digital inclusive finance and farmers'income and shed light on increasing farmers'incomes and promoting the high-quality development of county economies.
