In face of the inadequacy of Western theories in the practice of knowledge sharing in China, the local culture is increasingly regarded as an important incentive to interpret the knowledge sharing among Chinese employees. This paper selects face orientation as a typical variable of Chinese local culture, and in line with the “Double Subjects” of face, studies the effects of selfface orientation and others face orientation on knowledge contribution intention and knowledge acquisition intention, and the moderating effect of TMX. A questionnaire survey of 339 enterprise employees in coastal areas shows that: selfface orientation promotes knowledge contribution intention and restrains knowledge acquisition intention. Othersface orientation promotes knowledge acquisition intention and inhibits knowledge contribution intention; team member exchange can not only weaken the promotion effect of selfface orientation and othersface orientation, but also weaken the inhibition effect of selfface orientation and othersface orientation.
