Based on the field survey data of 764 rice and wheat growers in Hubei and Henan provinces,this study uses an endogenous switching probit model to evaluate the impact of new media application on farmers’ biopesticides adoption under a counterfactual framework. At the same time,the study examines the difference in the effects as to different types of new media,and further explores the influence mechanism. The following resultes are indicated. First,the use of new media has a significant positive impact on farmers’ adoption of bipesticides. It showed that under counterfactual assumptions,if farmers who used new media had not used it,their biopesticides adoption probability would decrease by 26.5%,and if farmers who did not use new media had used it,their biopesticides adoption probability would increase by 32.9%. Second,different types of new media have different impacts on farmers’ biopesticides adoption. The short video is found to have a larger impact on farmers’ adoption of biopesticides than social communication,and content aggregation has less impact than the above two. Third,the promotion effects are particularly significant for farmers who have a higher education level and smaller farm land. Last,information capacity plays an intermediary role in the process of new media influencing the farmers’ biopesticides adoption . Therefore,it is suggested to improve the agricultural technology information dissemination mechanism,increase the supply of effective information,reinforce information technology education and training,and orderly guide farmers with different capital endowments to use new media to acquire agricultural technology information knowledge.
