There are some methods used in the research on estimating customers’ acceptance of GM foods overseas, but similar researches are still very few in China. Based on the survey results of 300 families in Shanghai, in this thesis the method Contingent Valuation Surveys is used, it is found that people’s cognition of GM food is quite limited. Therefore bio-technological knowledge of agricultural should be further popularized in China. Although most of the consumers claim that they concern foods’ safety and nutrition most, but price and income turn to be the most significant two factors in the survey. Consumers in Shanghai support the labeling of GM food strongly, and the antipathy of GM plant foods is less than that of GM animal foods. The result of binary logit regression shows that consumers tends to purchase non-GM food, only when the average price of GM food is 28.55% lower than their traditional equivalence, they will shift to buy GM foods.
