Taking China's provincial panel data from 2010 to 2021 as a sample, the entropy weight method is used to measure and calculate the agricultural science and technology innovation and the resilience of grain production system. In addition, the fixed effects model is also applied to analyze the impact of agricultural sci-tech innovation on the resilience of grain production and the mechanism of action. The study shows that agricultural sci-tech innovation significantly improves the resilience of the grain production with a positive spatial spillover effect. Heterogeneity analyses show that agricultural sci-tech innovation has a greater impact on the major grain-producing regions and central China than on the non-major grain-producing regions and east China. Further mechanism analysis indicates that agricultural sci-tech innovation promotes grain production resilience by reducing the amount of chemical fertilizer applied in agriculture, increasing the share of agricultural mechanized operation service personnel and the level of agricultural mechanization. Therefore, it is necessary to continuously strengthen the leading role of sci-tech innovation, accelerate the substitution of agricultural factors, promote the transformation to low-carbon and green agricultural industry, and guide the radiation of innovation and technological spillover, so as to give full play to the role of agricultural sci-tech innovation in enhancing the grain production resilience.
