知识溢出视角下环境友好型生产技术对贫困地区农户生产效益影响分析——以贵州省茶叶主产区茶农为例

Impact of Environment-Friendly Technology on Farmers′ Production Benefit in Poverty-Stricken Areas——From the Perspective of Knowledge Spillover

推广环境友好型生产技术是推进贫困地区农业发展和生态环境协同发展的重要途径。贫困地区农户作为农业生产技术的使用主体,能否准确采纳环境友好型生产技术,并通过其获得经济效益,将对环境友好型生产技术推广产生关键性影响。本文从知识溢出视角,利用贵州省茶农实地调研数据,就环境友好型农业生产技术对贫困地区农户生产效益的影响进行分析。研究结果发现:环境友好型农业生产技术对贫困地区农户具有显著的增收效应;农户的显性知识溢出效应能进一步扩大环境友好型农业生产技术带来的增收效应,而农户的隐性知识溢出效应对其增收效应影响不显著。

Promoting environment-friendly production technology is an important way to promote the coordinated development of agriculture and ecological environment in poverty-stricken areas. From the perspective of knowledge spillover, this paper analyzes the impact of environment-friendly technology on farmers’ production benefit in poverty-stricken areas by using the field survey data of tea farmers in Guizhou Province. The results show that:Environment-friendly technology has a significant effect on the benefit increase of farmers in poverty-stricken areas. The explicit knowledge spillover effect of farmers can further expand the benefit effect brought by environmentfriendly technology, but the implicit knowledge spillover effect of farmers has no significant effect on the increase of income effect of environment-friendly technology.
