理工科研究生对转基因食品认知态度的再调查

Reinvestigation in Cognition Attitudes of Science and Engineering Postgraduates toward Genetically Modified Foods

为了进一步研究理工科研究生对转基因食品的认知态度和购买意愿的变化,继2010年12月调查之后,2013年6月随机调查了490名理工科研究生,结果表现出新特征:除了对转基因生物和转基因食品仍旧保持较高程度的认知,共有78.02%的人持"谨慎支持"或"中立"态度,持绝对"支持"或"反对"的比例较小;在价格相当时优先购买传统食品的比例由99.30%下降到77.29%;降价对消费倾向影响较大,当转基因食品便宜40%时总计会有61.12%的人购买该类食品,但仍有11.84%的人表示价格再低也绝不购买转基因食品。分析结果表明:理工科研究生对转基因食品的认识较为理性;专业知识的学习对于转基因生物认知态度有重要影响;多数人对转基因生物持支持或谨慎支持态度;价格因素是影响消费倾向的关键因素。

To further study changes of cognition attitudes and purchasing intention of science and engineering postgraduates towa~ the genetically modified foods, a reinvestigation is carried out in June 2013, after the investigation in December 2010. In this investigation, 490 science and engineering postgrad- uates were randomly selected as samples. Results show novel characteristics that the postgraduates still have a relatively high degree of cognition to GM organisms and GM foods. Specifically, the ratio of the postgraduates who cautiously support or hold neutral attitude to the GM foods is 78.02 % ; the ratio of postgraduates who absolutely approve or oppose them is relatively small; and when the prices are comparative, the ratio of postgraduates who prefer to purchase conventional foods is reduced to 77.29% from 99.30%. Purchasing intention results show that the price has great influence on consumption tendency, 61.12% of the postgraduates would purchase the GM foods if the price were reduced by 40%. However, still 11.84% of the postgraduates claimed that they would never buy the GM lbods even if thc price is as low as they could be. The results demonstrate that the science and engineering post- graduates have relatively rational cognition to the GM foods; professional learning has significant influence on the cognition degree toward the GM foods; a majority of respondents hold support or cautiously support attitudes to the GM organisms; and the price is the key factor influencing the purchasing intention.
