In this study, Logit and Poisson models were estimated to analyze the determinants of farmers' adoption willingness and intensity of integrated mitigation technologies for rice-based cropping systems in China. It was shown that the awareness of climate change and technology demonstration would increase the adoption willingness and adoption intensity, respectively. Besides, extension services, access to credit and irrigation infrastructure were also associated with farmers' adoption willingness and intensity of mitigation technologies. Based on these results, policy recommendations encouraging farmer's adoption of new GHGs mitigation technologies are also discussed from above aspects.
