摘要
本文以橙汁中的添加剂为例,采用随机n价拍卖机制模拟真实的市场环境,引入Tobit模型与多元线性模型,考察消费者使用鲜榨橙汁交换含有添加剂的橙汁时,愿意接受的补偿意愿以及橙汁中添加剂的正、负面信息对消费者食品添加剂风险感知的影响。结果表明:消费者对橙汁添加剂的负面信息赋予更高的权重,对橙汁添加剂具有较高补偿意愿的并不是对添加剂不了解的消费者,而是有些了解的消费者;对信息的加工能力、对自身及家人健康的关注程度以及对信息后果预见能力等变量都对消费者的补偿意愿产生影响;消费者的补偿意愿具有锚定效应,受其初始报价的影响显著。因此,及时且准确地发布有关食品安全风险的信息,努力在源头上遏制媒体尤其是食品网络舆情对消费者食品安全风险的误导,基于消费者群体间的差异采用不同的交流策略,消除消费者的食品安全恐慌是构建食品安全风险交流机制最基本的内容。
In this study,a real market environment was simulated via a random nth-price auction.Consumers' willingness to accept orange juice containing additives in place of freshly squeezed orange juice,as well as the effects of positive and negative information of orange juice additives on consumers' risk perceptions of food additives,was then examined using Tobit and multivariate linear models.Finally,three findings were obtained,a.Negative information of orange juice additives was given a higher weight by consumers;consumers with some knowledge about additives,rather than those without knowledge about additives,had a higher willingness to accept,b.Information processing capacity,concern about the health of themselves and their families,and the ability to foresee the consequences of information had an impact on consumers' willingness to accept,c.The initial bid had a significant anchoring effect on consumers' willingness to accept.Therefore,the most basis task in building the food safety risk communication mechanism is to eliminate consumers' scares about food safety by disclosing timely and accurate information about food safety risks,preventing misguidance in food safety risks by the media,especially online public opinion about food,at the source,and employing different communication strategies based on the differences among consumer groups.
