摘要
强制性标签政策可能对转基因产品的消费和贸易产生很大影响，其程度主要取决于消费者对转基因产品的接受程度，以及转基因标签对消费者态度和行为的影响。本研究利用超市实际销售数据分析转基因食用油强制标签政策的实施是否影响消费者的购买行为，发现标签政策实施后转基因食用油的市场份额下降，下降幅度虽然不大但统计学上显著。
The mandatory labeling regulation is expected to have a significant impact on consumption and trade of GM products. However, the degree of the impact is largely determined by consumers＇ acceptance of GM products and consumers＇ attitude and behavior influenced by labeling. This paper uses actual sales data of edible oils from a supermarket to examine if Chinese consumers＇ behavior changes after the enforcement of mandatory GM foods labeling regulation. It is found that the market share of GM edible oils did decrease as a resuit, though small in absolute terms but statistically significant.
