摘 要: 本文着眼于农户禀赋对农业技术采纳决策的影响 ,以我国西部陕西、宁夏、四川三省区的 41 9个农户样本、2 8个村级样本为依据 ,在修正了现有理论模型的基础上 ,对小麦新品种技术和蔬菜、水果的保护地生产技术两种在采纳成本上分属不同层次的技术进行分析。在分析过程中 ,我们把机会成本引进模型 ,得出新技术的进入门槛和技术采纳的机会成本共同影响着农户采纳农业新技术的可能性等相关结论 ,从而提出改变技术推广思路等相关建议。 This paper, which is based on 419 farmer samples and 28 village samples drawn from three provinces: Shaanxi, Ningxia, Sichuan in West China, focuses on how the farmer's endowments influence the adopting decision on agricultural technology. We revise the popular “adoption condition' and introduce a function of opportunity cost into the farmer decision model to fulfill the above object, in which the new variety technology of wheat and the protection mode in vegetable or fruit planting is concerned. The analysis shows that it is not only the threshold but also the opportunity cost that affects the probability of a farmer's adopting new technology, and, accordingly, the mode of agricultural technology diffusion practiced nowadays should be adjusted.
