| 目的 信息化背景下的新媒体应用为生物农药技术的推广提供可行路径。方法 文章基于农业技术推广扩散理论和双向沟通理论，利用湖北省和河南省789份农户调研数据，采用内生转换概率模型构建“反事实”分析框架，实证检验信息化背景下农技推广方式对农户生物农药施用行为的影响。结果 （1）接受传统农技推广农户生物农药施用比例为37.77%，接受新媒体农技推广农户生物农药施用比例为28.77%；（2）“线上”或“线下”农技推广方式对农户生物农药施用均具有显著促进效应，从平均处理效应来看，传统农技推广方式对农户生物农药施用行为促进效果最好，新媒体农技推广方式次之，二者对农户生物农药施用行为具有叠加效应和互补效应；（3）针对小规模农户生物农药推广应该以传统农技推广方式为主，而对大规模农户则应采用传统和新媒体农技推广结合方式。结论 因此应拓宽生物农药技术推广渠道，加强农村信息化建设；创新农技推广形式，促进线上线下互动交流；同时实行差异化精准化推广。 |

| Abstract: |
| Under the background of Internet informatization, the application of new media provides a feasible path for the technology extension of biopesticide. Based on the theory of technological diffusion and bilateral communicate, 789 household survey data from Hubei and Henan province were used for empirical evidence. And The ESP model was used to construct a “counterfactual” scenario to estimate the effect of agricultural extension methods on farmers' biopesticide application behavior. Results were showed as follows. Firstly, the proportion of farmers who adopted traditional agricultural extension of biopesticides was 37.77%, while it was 28.77% for farmers who adopted new media agricultural extension. Secondly, “online” or “offline” agricultural extension methods both promoted the farmers' application behavior of biopesticides significantly. The estimated results of treatment effect ATT and ATU showed that traditional offline agricultural extension methods were more beneficial for biopesticide application, compared to online new media agricultural extension. And they had a superimposed and complementary effect on promoting farmers' biopesticide use. Thirdly, for smaller-scale farmers, biopesticide extension should be traditional offline agricultural extension, while a combination of traditional and new media agricultural extension should be used for larger-scale farmers. Therefore, we should broaden biopesticide extension channels, strengthen rural Network information, innovate agricultural extension forms, promote online and offline integration, and implement differentiated and precision biopesticide extension. |
