Based on the panel data of China's three grain functional areas from 2011 to 2020, a quantitative index system of agricultural science and technology innovation was constructed, and then the level of agricultural science and technology innovation and carbon emission level of grain production were calculated. A dynamic panel model was used to test the inhibition effect and influence path of agricultural science and technology innovation on carbon emission of grain production. The results found that from 2011 to 2020, the level of agricultural science and technology innovation in the three grain functional areas showed an increasing trend, the carbon emissions of grain production decreased, and the inter-group heterogeneity was obvious. Agricultural scientific and technological innovation had a significant inhibitory effect on the carbon emission of grain production, and this effect was more significant in the main grain marketing areas. The technology effect and the human capital effect played an important role in the process of carbon reduction in agricultural science and technology innovation. It was recommended to accelerate the pace of agricultural science and technology innovation, continue to achieve carbon reduction in grain production through agricultural science and technology innovation, pay attention to the improvement of production efficiency, resource utilization efficiency and human capital level, and formulate corresponding policies for carbon reduction according to the heterogeneity of the three grain functional areas to realize the green upgrading and transformation of grain industry.
