Accelerating the promotion of water-saving irrigation technology is an important way for China to realize the transformation from water-dependent agriculture to water-saving agriculture. Here we use the example of drip irrigation technology and structural equation modeling to analyze how technology perception and subsidy policy satisfaction impact the initial phase and follow-up phase of farmers’ adoption, based on 354 households’ survey data from Minqin County (among them, 156 households have not used drip irrigation and 198 households have adopted). When they adopt technology from the initial phase to the follow-up phase, farmers' perception of ease to use improves, however, their perceived usefulness and subsidy policy rationality decrease. Compared with the perception of ease to use, the influence of perceived usefulness on farmers’ willingness to adopt increases, and the influence of subsidy policy on farmers’ willingness to adopt is further enhanced. A policy implication is that technology promotion such as advertising activities, training and field demonstration in initial adoption phase are significant in today's technology popularization. More input should be applied into technology research and development to improve the effect and sustainability of technology adopting at the same time. Appropriate adjustment should be given in subsidy standard and manners for improving the implementation effects of subsidy policy, and more attention should be paid to policy requirements of farmers in the follow-up adoption phase, for their opinions on the subsidy standard and means are valuable.

加快节水灌溉技术推广,鼓励农户持续采用,是实现水资源依赖型农业向节水型农业转变的重要途径。本文在划分技术采用阶段的基础上,重点从技术认知和补贴政策认知两方面探讨了农户采用意愿。结果表明,不同采用阶段农户的技术认知和补贴政策认知不同,并且这种认知变化也在农户采用意愿上得到反映。具体结论及政策启示如下: (1)在技术认知方面,从初始采用阶段到后续采用阶段,农户感知节水技术的易用性有所提升,而感知技术的有用性有所下降,两者对农户采用意愿的影响也逐渐从无差异转变为后者高于前者。实地调研了解,初始采用阶段农户对采用新技术普遍存有畏难情绪,并在技术采用后得到一定的缓解,但由于技术采用效果未达到预期,促使其后续更加关注技术的有用性。因此应进一步加强技术宣传、培训、田间示范,以及技术研发,在帮助初始采用阶段农户克服畏难情绪的同时提升技术采用效果,提高其技术采用的持续性。 (2)在补贴政策方面,后续采用阶段农户感知补贴政策的合理性虽然低于初始采用阶段,但这一因素逐渐成为影响农户采用意愿的最主要因素。可以看出,技术采用前,农户对补贴政策的认可度相对较高,而在技术采用后农户开始对原有补贴政策产生质疑。鉴于后续采用阶段农户对技术采用成本、收益和风险的认知更加清晰,因此建议未来补贴政策的制定应更多地参考这部分农户的意见,适当调整补贴标准与补贴方式,从而提高政策效果。 The authors have declared that no competing interests exist.
