Based on the provincial data of Inner Mongolia from 2000 to 2020, this paper calculated agricultural carbon emissions, and analyzed their time series changes, the driving and restraining factors of agricultural carbon emissions in Inner Mongolia using the LMDI index decomposition method and the contribution rate of influencing factors on this basis. The results show as follows.(1) From 2000 to 2020, the total agricultural carbon emissions in Inner Mongolia show a fluctuating upward trend, and the intensity of agricultural carbon emissions continues to decline. Carbon emissions from rice planting, livestock and poultry breeding, agricultural land utilization and straw burning increase.(2) The contribution rates of agricultural production efficiency factor and labor force scale factor are-231.92% and-52.28%, and the carbon emission reductions are 10.411 2 Mt and 45.922 9 Mt, respectively. The agricultural production efficiency factor has a more obvious inhibition effect on the agricultural carbon emission. The contribution rates of agricultural structure factor and economic development level factor are 3.15% and 381.35%, and the increased carbon emissions are 0.623 1 Mt and 75.512 Mt, respectively. The promotion effect of economic development level factor is far higher than that of agricultural structure factor. According to the results of this study, the following policy recommendations are put forward: develop new treatment methods for the livestock and poultry manure, and optimize the feeding and management methods; improve the utilization rate of agricultural input factors and strengthen the regional cooperation in agricultural development; reduce agricultural inputs and improve the recovery rate and utilization rate, so as to achieve the reduction of agricultural carbon emissions and the high-quality development of low-carbon agriculture.
