一些研究发现，互联网的使用可以增进农户病虫害绿色防控技术的采纳率，但是没有区分互联网不同使用（有无生产性使用）的影响。互联网属于技能偏向型技术进步，对普遍低学历的农民来说“使用”不代表“会用”。利用2019年2544名职业农民的调查数据统计发现，20.32%的农民只使用通信娱乐功能，他们的病虫害绿色防控技术采纳率仅为30.95%，而有生产性使用的农民的采纳率为44.55%。在运用 Logit、Probit、LPM回归的基础上又使用双重稳健模型IPWRA、AIPW检验，结果稳定一致。双重稳健模型表明，有生产性使用的农民采纳病虫害绿色防控技术的概率提高了6.55个百分点，相当于采纳概率提高了15.68%，具有统计和经济意义上的显著性。

Previous studies have found that the uses of the internet can increase the adoption of green technology for preventing and controlling diseases and pests among farmers. However, they do not distinguish between the effects of the different uses of the internet (with or without productive use). The Internet is a skill-biased technological progress which majority of the under-educated farmers can only use but don’t know how to make good use of. Based on the data and statistics of 2544 skilled farmers in 2019, it is found that 20.32% of them use the internet only for communication and entertainment. The adoption rate of green technology for preventing and controlling diseases and pests is just 30.95% while the adoption rate among the professional farmers is 44.55%. Logit, Probit, and LPM regression analysis have been used to analyze the statistics and the methods of double robust model IPWRA and AIPW have been used to validate the results. The findings echo one another. The result from double robust model shows that the adoption rate of green technology for preventing and controlling diseases and pests among the professional farmers increased by 6.55%, and that means the adoption rate increased 15.68%, which is statistically and economically significant.
