英文摘要：

The rediffusion intention of word-of-mouth is the only source of the dynamism of word-of-mouth spread,and the research of its determinants is critical.According to the communication and persuasion theory,a framework of determinants of online word-of-mouth re-diffusion intention is put forward from the perspective of the source,content,and receiver.The tested results show that word-of-mouth source trustworthiness,content playfulness,receivers＇ altruistic motive and self-enhancement motives are the determinants of online word-of-mouth re-diffusion intention.Because word-of-mouth is a two-edged weapon which has both positive and negative effects,companies should control these determinants from both directions in order to maximize advantages and avoid disadvantages.
