摘要
本文以山东省445户菜农为例,采用实验经济学方法测度菜农的风险厌恶程度以及采用项目反应理论模型测度菜农的信息获取能力,在此基础上借助Logit模型分析风险厌恶程度和信息获取能力对菜农绿色防控技术采纳行为的影响,并探讨信息获取能力是否有助于缓解风险厌恶对菜农绿色防控技术采纳行为的抑制作用。研究结果表明:样本菜农大部分为风险厌恶型;能够利用的信息获取渠道(尤其是区分度较高的渠道)数目越多的菜农,其信息获取能力越强;风险厌恶程度对菜农绿色防控技术采纳行为产生显著的负向影响,信息获取能力对菜农绿色防控技术采纳行为产生显著的正向影响,且信息获取能力能够缓解风险厌恶对菜农绿色防控技术采纳行为的抑制作用。
This article uses methods from experimental economics and an item response theory model to measure the risk aversion and information acquisition ability of vegetable fermers, based on data collected from 445 vegetable fanners in Shandong Province. The study examines the intact of vegetable fermers' risk aversion and information acquisition ability on their adoption behavior of green control techniques, and discusses vdiether the information acquisition ability is helpfill to alleviate the inhibitory effect of risk aversion on the adoption behavior of vegetable fermers' green control techniques. The results show that most of the sample vegetable fermers are risk-averse, and the more the number of information acquisition channels they have (especially the channels witii higher difierentiation), the higher the level of information acquisition ability they have. The degree of risk aversion has a significant negative impact on their adoption behavior of green control techniques, and the mformation acquisition ability has a significant positive effect on the adoption behavior of green control techniques. And information acquisition ability of vegetable fermers can alleviate the inhibition effect of risk aversion on the adoption of green control techniques.
