This study examined the influence of consumers' knowledge on their perceptions and purchase intentions toward genetically modified foods, and the implications of these consumer responses for sustainable development in the food industry. This study distinguished between objective and subjective knowledge and identified how an imbalance between the two knowledge types influenced consumers' attitudes and purchase intentions toward genetically modified foods. Results of a multinomial regression analysis showed that consumers with higher levels of education, income, and food involvement and more exposure to negative information about genetically modified foods tended to overestimate their actual knowledge level. The overestimation group showed a higher risk perception, lower benefit perception, and lower intention to purchase genetically modified foods than other participants. Consumers with less education and higher income were more likely to underestimate their knowledge.
本研究考察了消费者知识对其对转基因食品的认知和购买意愿的影响，以及这些消费者反应对食品行业可持续发展的影响。本研究区分了客观知识和主观知识，并确定了两种知识类型之间的不平衡如何影响消费者对转基因食品的态度和购买意愿。多项回归分析的结果表明，受教育程度、收入和食品参与度较高，接触更多关于转基因食品的负面信息的消费者往往会高估自己的实际知识水平。与其他参与者相比，高估组表现出更高的风险感知、更低的收益感知和更低的购买转基因食品的意愿。受教育程度较低、收入较高的消费者更有可能低估自己的知识水平。
