Based on EKB, H-S and consumption value model, combined with the characteristics of green food, this paper constructs a model with three dimensions: the dissemination of green information, the property of green product, and the purchasing behavior of consumer. Through the questionnaire survey, an analysis has been done to explore the degree of direct relationship between the dissemination of green information and the property of green product, and how they impact the purchasing behavior of consumer directly. It is found that the dissemination of green information has universal and direct impact on the property of green product, and the dissemination of green information and the property of value of green food have direct impact on the purchasing behavior of consumer.
