Agricultural resources and environment are the basic resources and necessary conditions for the development of agricultural production and realization of agricultural economic growth. Analyzing the relationship between agricultural economic growth and planting non-point source pollution from the perspective of spatial effects can help to explore a new direction for prevention and control of planting non-point source pollution, and provide theoretical support for promoting the implementation of the policy of prevention and treatment of planting non-point source pollution. Based on the provincial panel data from 2000 to 2019, this study used the equal-standard pollution load method to measure the planting non-point source pollution emissions; and used the spatial Durbin model to empirically analyze the spatial effect of agricultural economic growth, consumption capacity, technological progress, agricultural modernization level, risk perception, financial support, disaster situation, and industrial structure on the emission of planting non-point source pollution, and to split the spatial effect of the influencing factors into direct and indirect spatial effects. The results are as follow: 1) A significant positive global spatial autocorrelation among the planting non-point source pollution in 31 provinces (cities, autonomous regions) was noted. In 2019, the spatial pattern was characterized by “high-high” and “low-low” aggregations, and the agglomerations were mainly in large agricultural provinces and economically developed areas. 2) The planting non-point source pollution had a significant negative spatial spillover effect, with a spatial lag coefficient of −0.11, and agricultural economic growth had a significant effect on the region and adjacent regions in a mutually exclusive direction. 3) The results of the effect of decomposition showed that the direct and indirect effects of agricultural economic growth, consumption capacity, technological progress, agricultura
