摘　　要：在虚拟学术社区中,信任机制是影响用户知识共享的其中一个决定性因素。利用博弈论的方法建立社区成员的知识共享博弈模型,分析完全信息情境下用户的静态博弈和动态博弈,重点探讨知识共享主体间的信任关系对用户共享策略选择的作用。研究表明,在虚拟学术社区中,成员间的信任关系能有效缓解静态博弈中的囚徒困境,促进社区成员动态博弈中在较小的折现因子条件下选择知识共享的策略。Trustmechanism is a decisive factor of users＇ knowledge sharing behavior in academic virtual community. Game models of knowledge sharing among members are established from the perspective of game theory. Static game model and dynamic game model with complete information are analyzed. The effect of trust relationship among members in knowl- edge sharing game is explored. The research results show that the trust relationship among the members could alleviate the prisoners＇ dilemma effectively in static game and promote community members to choose knowledge sharing strategy when the discount factor is lower under the dynamic game in academic virtuai communities.
