中文摘要:

      目的 调查消费者对于转基因食品的认知、态度, 以及对于不同标识方式下的溢价支付意愿。方法 通过决策树的计量方法, 研究了在不同标识方式下影响消费者对非转基因食品溢价支付意愿的因素及高意愿人群特征。结果 消费者对于非转基因标识方式下的溢价支付意愿高于转基因标识方式下的支付意愿, 越是了解转基因的消费者越不愿意为非转基因产品支付过高溢价, 中老年人的溢价支付意愿普遍高于年轻人。 结论 在不同的标识方式下的溢价不同表明部分消费者对转基因食品仍存在误解, 需要重视为转基因食品正名、尽快推进非转基因食品认证方式的发展。

英文摘要:

      Objective To investigate consumers’ cognition and attitude towards genetically modified food and their willingness to pay premium under different labeling methods. Methods Through the measurement method of decision tree, the factors those affecting consumers' willingness to pay premium for non-genetically modified food under different labeling methods and the characteristics of high willing groups were studied. Results Consumers’ willingness to pay premium under non-genetically modified labeling was higher than that under genetically modified labeling. The more consumers knew about genetically modified, the less willing they were to pay high premium for non-genetically modified products. Middle-aged and elderly people’s willingness to pay premium was generally higher than that of young people. Conclusion The different premiums under different labeling methods indicate that some consumers still have misunderstandings about genetically modified food. It is necessary to pay attention to rectifying the names of genetically modified food and promote the development of non- genetically modified organism food certification methods as soon as possible.
