Abstract: The implementation of low carbon rice farming aims to increase carbon sinks and to reduce carbon emission.Low-carbon and high-yield is an inevitable choice to achieve the goal of "double carbon" and ensure the "win-win" of national food security. Based on the survey data of 2 173 farmers in Jiangxi Province, this paper introduced the IMB intervention model framework, and used the ordered Probit model and the mediating effects model to empirically test the influencing factors and mediation paths of farmers ' adoption of low carbon rice farming behaviors. The results showed that (1) farmers did not adopt low carbon rice farming behaviors at a high level, and the largest number chose to apply organic fertilizer. (2) In the IMB intervention model, information accessibility, technology understanding, importance motivation, technology training, production communication behavior, and imitation convergence behavior played a significant positive role. (3)Mediating effects analysis showed that technology information could promote farmers' adoption behavior through adoption motivation and behavioral skills, and behavioral skills could also be influenced by adoption motivation to enhance farmers' adoption level. In view of this, in order to promote farmers' adoption of low carbon rice farming behavior, we should strengthen the popularization of low carbon rice farming technology, highlight the demonstration effects of technology adoption, improve the training of low carbon rice farming technology, establishment of an incentive mechanism for low carbon rice farming technology, and carry out relevant low carbon rice farming science and technology research.
