农业技术培训方式对农户农业化学投入品使用行为的影响——源自实验经济学的证据

The Impact of Agricultural Technical Training on Farmers' Agrochemical Use Behavior:Evidence from Experimental Economics

本文采用参与式研究方法和实验经济学方法,通过设计不同的农业技术培训实验,实证分析了农业技术培训方式对农户化学投入品使用行为的影响及其作用机制。研究结果发现:①农业技术培训能够降低农户的农业化学投入品使用量,且随着培训程度的加深,农户的农业化学投入品使用行为愈加合理;②培训基础上的完全技术指导对改善农户农业化学投入品使用行为的效果好于仅仅提供技术培训的效果,农户农业化学投入品使用行为的合理化需要借助农业技术人员开展广泛而深入的现场指导;③相比于邻村未参加农业技术培训的农户,同村未参加农业技术培训的农户的农业化学投入品使用行为更加合理,农业技术培训具有一定的技术扩散作用。

Using participatory approaches and experimental economic methods,this paper analyzes the impact of different types of agricultural technical training activities on farmers' agrochemical use behavior.The results show that,firstly,the agricultural technical training can reduce the amount of farmers' agrochemical inputs.The more agricultural technical training farmers receive,the more rational their agrochemical use behavior will be.Secondly,the impact of completed technology guidance on farmers' agrochemical use behavior is greater than the impact of agricultural technical training.The rationalization of farmers' agrochemical use behavior needs the help of technicians' in-depth on-site guidance.Thirdly,the agrochemical use behavior of non-participated farmers in the same village is more rational than non-participated fanners in the neighboring village.Agricultural technical training has technical diffusion effects.
