Abstract: With the methods of literature review,induction and deduction,the forming and growing of sport consumption is displayed systematically.The results are found that the forming and growing of sport consumption is determined by a motive power structure that is composed of sport consumption conscious,sport consumption goods and sport consumption behavior.Under the action of these three structural elemental,the forming of sport consumption appears to have two kinds of direction:the one is higher involvement consumption behavior that is driven by sport consumption consciousness to precipitate the accomplishment of the whole motive power structure,the other is lower involvement consumption behavior that is driven by sport consumption goods to precipitate the accomplishment of the whole motive power structure.The first cylices process of this dynamical system not only marks the beginning of the forming of sport consumption but also is a beginning of the growing of sport consumption.In addition,with the increasing of sport consumer's self-directed learning,the dynamical system will be cycling just like the rolling wheels to push forward the growing of sport consumption that appears three stages.
