【摘要】：目前动物食品安全是我国关注的热点问题,许多安全隐患源于饲养过程中滥用或不规范使用兽药。运用期望效用理论和信息不对称理论,探讨风险偏好、外部信息有效性和农户使用违禁兽药之间的关系,并基于辽宁省生猪养殖户的调研数据,对上述关系进行实证检验。结果表明,农户的风险规避类型和获取外部信息失效是使用违禁兽药的显著影响因素。相应的政策启示是:推行有效农业政策弥补风险规避行为,实现分散转移风险;同时通过对兽药、饲料零售商进行培训、管理和监督,以及加强基层兽医部门和农业院校的兽药信息服务功能,确保农户获得准确完整的兽药信息,降低农户获取信息的交易成本。
[Abstract]:At present, animal food safety is a hot issue in our country. Many hidden dangers are caused by misuse or nonstandard use of veterinary drugs.Using the theory of expected utility and asymmetric information, this paper discusses the relationship between risk preference, the effectiveness of external information and the use of prohibited veterinary drugs by farmers. Based on the survey data of pig farmers in Liaoning Province, the above relationship is empirically tested.The results showed that the types of risk aversion and the failure to obtain external information were significant influencing factors in the use of prohibited veterinary drugs.The corresponding policy implications are: to implement effective agricultural policies to compensate for risk aversion and to spread the transfer of risks; at the same time, through training, management and supervision of veterinary drugs and feed retailers,And strengthen the function of veterinary medicine information service in primary veterinary departments and agricultural colleges, ensure farmers to obtain accurate and complete veterinary drug information, reduce the transaction cost of farmers to obtain information.
