摘要
本文旨在探讨不同风险特质的农户采用节水灌溉技术需求异质性中的作用机制,为寻求农户最优风险管理策略以及为构建节水灌溉技术采用的政策激励机制提出政策建议。利用甘肃省张掖甘州区节水灌溉技术推广示范区540份农户调查问卷,探讨了风险偏好、风险认知对农户节水灌溉技术采用意愿的作用机制。研究发现:(1)节水灌溉技术具有降低干旱风险损失的功能,因此农户采用节水灌溉技术意愿随风险认知水平的提升而增加,而随风险偏好程度增加而减弱;(2)农户风险认知、风险偏好交互决定了节水灌溉技术采用意愿,即当农户感知到更大风险时,风险喜好型农户采用节水灌溉技术的意愿显著低于风险厌恶型农户采用意愿;当农户属于风险喜好型时,风险认知较高农户采用节水灌溉技术的意愿显著高于风险认知较低农户采用意愿;(3)农户风险偏好通过风险认知的中介作用,间接影响农户节水灌溉技术采用的意愿,风险厌恶型农户随其风险认知水平的增加而对增加节水灌溉技术采用意愿变得更加强烈和显著;同时,研究也发现风险规避型农户并未因风险认知水平提升而提升对节水灌溉技术采用的意愿。
Here, we explored the mechanism under different risk characteristics of farmers by irrigation demand heterogeneity. This work will help farmers seek optimal risk management strategies and policy incentive recommendations for the construction of water-saving irrigation technology policy. We used the Gansu province Zhangye Ganzhou district water-saving irrigation technology demonstration area and 540 questionnaires to discuss the mechanism in scenarios of risk preference and risk perception on farmer willingness to adopt water-saving irrigation technology. We found that the willingness of farmers to adopt irrigation technology increases with increasing risk perception, but decreases with the perception and risk preference interaction determines increase in risk preference. Farmer risk water-saving irrigation technology adoption intention. When farmers perceive more perception risk, the type of risk preference farmers adopt water-saving willingness significantly lower than risk averse farmers＇ willingness to adopt. When farmers are the risk preferences, the cognitive level of risk perception high farmers adopt water- saving willingness was significantly higher than that of low risk cognition of farmers＇ willingness to adopt. Farmer risk preferences through the mediating role of risk perception, indirectly effect their willingness for water-saving irrigation technology： risk aversion farmers with high cognitive levels of risk in water-saving irrigation technology adoption willingness will become more intense and obvious, but the inhibition effect is more obvious. In order to avoid the risk of agricultural production and reduce income variability, agricultural production behavior tends to deviate from optimal economics. The social security system is not perfect in China and this will cause farmers to adopt conservative risk averse behavior. New irrigation technology extension should be to very cautious.
