Abstract: To explore the role of values in public’s attitude towards GM foods, based on sampling survey data, this paper demonstrates egoistic, altruistic, and biospheric values have different influence on perceived risks, perceived benefits, and attitude formation, taking example of GM rice. Moreover, we proved rationality of value-perception-attitude model and necessity of intermediary variable——perception using Structural Equation Model. Results indicate that people with strong egoistic values tend to perceive more benefits of GM rice and then have a more positive attitude towards it, while people who strongly endorse altruistic or biospheric values often perceive high risks of GM rice and are likely to have a cautious attitude. Upon this conclusion, the public’s attitude can be adjusted or changed by activating or strengthening their specific values under different circumstances.

摘要： 为探究隐含在风险技术公众态度背后的社会心理因素，以转基因水稻为例，利用抽样调查数据，论证了利己主义、利他主义和生态主义三种价值观对转基因水稻的感知和态度的影响有显著差异，并运用结构方程模型证明了感知这一中介变量的合理性和必要性。结果表明，利己主义者感知收益水平较高，因此对转基因水稻的接受程度也较高；利他主义者和生态主义感知风险水平较高，对转基因水稻的态度也较为谨慎。基于此结论，决策者可以更好了解不同价值观的公众在对待转基因安全性问题上的差异性和偏好，以助力公共决策的科学化和民主化。
