Based on the panel data of 30 provinces in China from 2006 to 2019, this paper measures the coupling coordination degree of financial inclusion and agricultural green total factor productivity (AGTFP), and uses Dagum Gini coefficient and spatial feature analysis method to study the regional difference and spatial agglomeration state of coupling coordination degree. On this basis, it further discusses the impact of the improvement of the coupling co scheduling of financial inclusion and AGTFP on the urban-rural income gap. The results show that the overall level of financial inclusion and AGTFP is low, but both show a slow upward trend, and the degree of coupling and coordination between the two continues to improve, which has developed from the very low coordination stage to the primary coordination stage. The two show the characteristics of alternating changes of the relative lag of AGTFP and the relative lag of financial inclusion. At present, the main performance is the relative lag of financial inclusion. There are great regional differences in the coupling coordination degree of financial inclusion and AGTFP, but this regional difference is gradually narrowing; And its spatial pattern presents the characteristics of global positive autocorrelation and local spatial pattern evolution. Further discussion found that the improvement of the coupling and co scheduling of financial inclusion and AGTFP is conducive to narrowing the income gap between urban and rural areas. Therefore, in order to realize the sustainable development of agriculture, it is suggested to coordinate the relationship between financial inclusion and AGTFP.
