1、农户农药施用行为及其影响因素一一来自鲁、晋、陕、甘四省693份经济作物种植户的经验证据李昊李世平南灵赵连杏北农林科技大学经济管理学院摘要:为深入分析经济作物种植户农药施用行为及其影响因素,并克服现有研宄方法的缺陷,以山东、山丙、陕丙和甘肃四省693份经济作物种植户微观调查数据为基础,运用W叶斯多变量和单变量Probit模型对种植户农药施用行为影响因素进行分析。结果表明:1)与多变量Probit模型相比,单变量Probit模型并未考虑种植户施药行为间的关联性,造成估计结果偏误。2)影响种植户施药行为的关键因素为受教育程度、风险规避、家庭人数、种植
2、年限、农业收入占比、农药施用技术培训和农药残留检测。在农药施用政策的制定中,应考虑种植户不同施药行为间的关联。此外,应建立健全农村农业保险体系,拓宽种植户收入渠道,强化施药技术培训并提高施药监管力度,从而规范种植户不合理施药行为,形成对食品安全和农业环境改善的源头治理。关键词:农药施用行为;影响因素;災叶斯估讣;经济作物种植户;作者简介:李昊(1988-),男,河南新乡人,博士研究生,研究方向:资源经济与环境管理。E-mail:lilhao23@163.com作者简介:李世平。E-mail:lishiping68@126.com收稿日期:201
