Designing and optimizing diversified subsidy policies for pesticide packaging waste recycling based on farmers’ preferences is the key to effectively motivating farmers to participate in recycling.Based on the survey data of 1060 farmers in 4 counties and 8 towns in Shaanxi Province，this paper uses choice experiment and random parameter Logit model to analyze farmers’ preferences for diversified subsidy policies for pesticide packaging waste recycling，and evaluate the impact of subsidy policies that incorporate farmers’ preferences on social welfare.The results show that：farmers are willing to accept diversified subsidy policies for pesticide packaging waste recycling，and prefer subsidy policies such as cash compensation，higher additional work hours compensation，diverse compensation criteria，spiritual rewards and related technical guidance.There are significant differences in the preferences of different farmers for the attributes of subsidy policies for pesticide packaging waste recycling.Farmers who are younger，have more education，have less family farmland，have higher family income，and have a higher degree of part-time work are more likely to participate in subsidy policy for pesticide packaging waste recycling.After the implementation of the diversified subsidy policies for pesticide packaging waste recycling incorporates farmers’ preferences，the average compensation surplus for farmers in Shaanxi Province is 193.19 yuan/year per household，and the total welfare improvement will be 1.48 billion yuan.Therefore，pesticide packaging waste recycling efforts can be combined with agricultural technology training programs in the future.It is also recommended to try the simultaneous use and organic combination of multiple compensation forms or bases to improve the efficiency of subsidy policies and reduce implementation costs.Priority should be given to encouraging some farmers to participate in pesticide packaging waste recycling，resulting in a certain demonstration effect conducting cost-benefit analyses of pesticide packaging waste recycling compensation policy formulation and optimization based on social welfare evaluation results.
