Abstract: Abstract Agricultural carbon emissions, as a major carbon emission after industrial carbon emissions, should be taken seriously. Reducing emissions relies heavily on technology. It is possible to explore the main path for reducing agricultural emissions through technology decomposition, which includes technical efficiency and technical progress. The technical efficiency and technical progress components of total factor productivity (broad technology) are first separated using the diethylaminoethyl (DEA)-Malmquist index method. Then, we use spatial panel econometric models and threshold models to analyze the relation between technical efficiency, technical progress, and agricultural carbon productivity. The results indicate that the decline in agricultural carbon emissions is a result of both technical efficiency and technical progress, and the contribution of technical efficiency is greater; this reveals that agricultural technical efficiency is the main technical channel to increase agricultural carbon productivity. Additionally, agricultural technical progress and technical efficiency have significant spatial spillover effects on the promotion of agricultural carbon productivity, which suggests that improvements in agricultural carbon production in nearby provinces are also facilitated by local agricultural technology to some extent. Interestingly, the threshold study further finds significant threshold effects of both technical efficiency and technical progress on agricultural carbon productivity under two threshold variables: farmers' education level and urbanization. These findings can provide effective policy guidance for agricultural emission reduction.
