Based on the traditional rational consumption model and consuming value model, this paper constructs a relationship model of green information, consumers’ perception of green food attributes and their green purchasing behavior. The result shows that the traditional consumer behavior model embedded in the green conception can still explain the green purchasing behavior. Moreover, the green information not only has direct impact on consumers’ buying process, but also has significant disturbance effects in the relationship between consumers’ perception of green food attributes and their green purchasing behavior.
