摘 要：[目的/意义]从博弈视角出发，基于不完全信息多阶段博弈模型对学术社交网络用户的知识贡献进行研究。根据用户在学术社交网络中知识贡献及接受所采取的不同博弈策略进行分析，为优化学术社交网络的用户服务总结相关启示。[方法/过程]以社会交换理论为基础，对学术社交网络中知识贡献者及免疫者的复制动态博弈方程进行假设和数学推演。[结果/结论]当贡献者贡献知识的成本降低、得益提高时，贡献者更趋向于执行强贡献博弈策略，反之，则更趋向于执行弱贡献博弈策略;当免疫者意识到不接受贡献知识可能的损失（机会成本）增大时，免疫者更趋向于采取弱免疫博弈策略，反之，则会趋向于执行强免疫博弈策略。据此，提出相关研究启示。

Abstract：[Purpose/Significance]From the perspective of game，the knowledge contribution of academic social network users is studied based on the multi-stage game model of incomplete information.According to the different game strategies adopted by the users in the academic social network，the knowledge and contribution of the game are analyzed to summarize the relevant enlightenment for optimizing the user service of the academic social network.[Method/Porcess]Based on the theory of social exchange，the hypothesis and mathematical deduction of the dynamic game equations of knowledge contributors and immunizes in academic social networks were carried out.[Result/Conclusion]When the cost of contributors contributing knowledge was reduced and the benefits were increased，contributors tended to implement strong contribution game strategies，and vice versa.When immunized people realized that they did not accept the possible loss of contribution knowledge（When the opportunity cost increased，the immune person tended to adopt a weak immune game strategy，and vice versa.Based on this，relevant research implications were proposed.

社交網络作为人们在线交流的重要工具之一，已涉及社会的各行各业[1]。如面向熟人关系的社交网络平台微信[2]，基于健身主题的社交网络平台Keep[3]，面向慢性病群体的社交网络平台慢友帮[4]。在学术科研领域社交网络也在不断渗透，如Researchgate[5-7]、Mendely[8-9]、Acadimic.edu[10-11]、小木虫[12]等，学术社交网络正日益受到学术界的关注，并成为图书情报领域的重要研究课题之一[13]。

随着学术社交网络的不断发展，其在学术交流和学术创新方面的积极作用越发明显[14-15]，但现阶段不同学术社交网络平……
