摘要:

基于黄土高原705位小麦种植农户的微观调查数据,本文采用田野实验的方法,实证分析了不确定厌恶对农户创新种子采纳的影响。研究结果表明,农户普遍是模糊厌恶与风险厌恶的,模糊厌恶和风险厌恶水平越高的农户,采纳小麦创新种子的可能性越低,且风险厌恶处于主导地位;农户信息获取水平的提高将缓解模糊厌恶对小麦创新种子采纳的负向影响,而银保互动有助于缓解风险厌恶对小麦创新种子采纳的阻碍作用;异质性分析表明受教育程度和收入较低的农户,其模糊厌恶和风险厌恶对农户采纳小麦创新种子的抑制效应更为显著。政府可从事前和事后两方面构建相关保障机制,以帮助农户更好应对生产过程中的各种不确定性,进而改善其模糊厌恶和风险厌恶态度,以提高农户对新技术的采纳率。

Abstract:

Based on the microdata of 705 wheat farmers in the Loess Plateau, this study empirically analyzes the impact of uncertainty on farmers’ adoption of innovative seeds using a field experiment.  The results indicate that farmers are generally ambiguity-averse and risk-averse.  In addition, farmers with higher ambiguity aversion and risk aversion are less likely to adopt innovative wheat seeds, where their risk aversion plays a dominant role.  Enhancing information access will alleviate the negative influence of ambiguity aversion on farmers’ adoption of innovative seeds, and interlinked insurance and credit contracts will be beneficial to ease the adverse effect of risk aversion on the adoption of innovative wheat seeds.  Meanwhile, heterogeneity analysis reveals that the inhibitory effects of ambiguity aversion and risk aversion on innovative seed adoption are more significant among farmers with lower education and household income.  The government can establish both ex-ante and ex-post relevant guarantee mechanisms to help farmers preferably cope with various uncertainties in the production process, remitting farmers’ ambiguity aversion and risk aversion to enhance new agricultural technology adoption rates.
