摘　　要：本文基于7个城市991份消费者的调研数据,采用多元无序Logistic回归模型检验了转基因食品陈述性偏好与购买行为之间偏差的存在性及其影响因素。研究表明,消费者陈述性偏好与购买行为的偏差表现为购买意愿与购买行为之间的认知失调现象;购买意愿与购买行为是否一致受消费者收入、对转基因食品的认知及标识政策等因素的影响,转基因食品的价格优势、消费者对转基因食品认知水平较低及对转基因食品标识政策缺乏关注是二者出现偏差的主要原因。本文提出应加强转基因科普知识及标识政策的宣传,进而提高消费者选择效率,为转基因食品的商业化发展创造良好市场环境。Based on the survey data of 991 consumers in seven cities across China,this paper did empirical analysis on the bias between statement preferences and purchase behavior regarding genetically modified foods by multiple unordered logistic regression models.It is found that the bias between statement preferences and purchase behavior is cognitive dissonance between the purchase intention and behavior.The household incomes,awareness of genetically modified foods,identity policy significantly affect the consistency of stated preference and purchase behavior.Price advantage of GMF,and cognitive level is relatively low,and lack of attention on labeling policy is major causes.Based on the above conclusions,this paper suggests that strengthening the advocacy of transgenic science and labeling policies of GMF,thus improving the efficiency of consumer choice,and creating a favorable market environment for the commercial development of genetically modified foods.
