Abstract:Cultural crisis in modern society has made individual self-identity a pressing problem,since people all make a coincident choice to consider consumerism a complement to the lack of meaning.As a result,consumption activities have evolved to a vital means of self-identity and physical body can serve as a window to show people’s self-identity.Therefore,the analysis of consumption activities related to physical body can reveal how consumerism influences individual self-identity mechanism.Meanwhile,such a research also indicates that consumerism is only a kind of expedient measure and it can not undertake the task to construct people’s life world,and that the prevalence of consumerism,on the contrary,merely creates more confusion for individual self-identity.
