Waste classification is a kind of pro-environmental behaviors in the residents private sphere. In order to promote waste classification, Beijing, Shanghai, Guangzhou and other cities have set up smart waste bins in their communities. In this paper, an attitude-intention-behavior model of residents' waste classification was constructed, and the moderating effect of supporting factors on residents' use of smart waste bins was studied. The results of the study show that a high level of support can effectively promote the development of residents' waste classification from intention to behavior, in which the specific measures include optimizing the hardware conditions for classification facilities of community waste and guidance of residents to learn methods how to do operation in an intelligent waste classification etc.
