Abstract: Based on management systems engineering theory，network organization is self-determination，dynamic，economic and expansible system.In view of the current limitations in studying information-sharing of network organization by the micro，static methods etc，the paper establishes the evolutionary game model of information-sharing in network organization based on the view of evolutionary game theory，and analyzes its dynamic evolutionary procedure.The results show that the system’s evolutionary direction is closely related to players’ payoff，and influenced by system’s initial status.Moreover，key factors that affect the system’s evolution，cooperation profit，initial cost of the cooperation，differences of information between peer and discount gene of the partners，are obtained and researched.

Key words: network organization, information-sharing, evolutionary game
