[Purpose/significance] Collaborative information seeking and retrieval is essentially a knowledge sharing process, describe its dynamic evolution process is the core issues of research.[Method/process] Epk is a potential discriminant function. In this paper, we took knowledge stock, knowledge structure and knowledge quality as variables, and constructed Epk to depict the participants' ability of knowledge sharing in the collaborative information seeking and retrieval; Then, we divided the collaborative group into two subgroups, which took Epk=50 as high and low potential threshold. We also discussed the influence factors of collaborative information seeking and retrieval from the following three aspects:collaborative participants' own factors and mutual influences, and influences of environment. Moreover,based on the above influence factors and game theory, we constructed a evolutionary game model of knowledge sharing in collaborative information seeking and retrieval. Finally, with the 2014 edition Matlab, we wrote the simulation programs, and performed multiple iterative simulations for evolutionary game model based on the given initial parameters.[Result/conclusion] The result shows that:the groups' strategies gradually tends to be stable after repeated game; the abilities of shared/learning knowledge and the ties in participants have positive impacts for knowledge sharing, and cost factors have negative effects for knowledge sharing; evolution game model converges to (1, 1), namely the high potential participants choose knowledge sharing strategies and low potential participants choose learning strategies; through continuous knowledge sharing and learning in collaborative process, participants' knowledge structure will be improved to different degrees, especially the improvement of knowledge supplier is particularly significant.
