This research tried to investigate the effects of network position on the cooperative behavior, focusing on the mediating role of organizational identification as a network mechanism. Compared to other researches, this study distinguished the type of network into friendship network and advice network. In a study of two student orchestra organization samples (N=37+66=103) we revealed two interesting findings. First, contrary to other studies, the indegree centrality in friendship network does not have significant effects on the organizational citizenship behavior (OCB), while the indegree centrality in advice network has positive and significant effects on the OCB. This result suggests that it is the advice network that intrigues the cooperative behavior in the temporal network organization setting such as TV production team, and orchestra team while the friendship network does not. Second, organizational identification completely mediated the link between the indegree centrality in advice network and OCB. That is, a person, who occupies the central position in the advice network, highly identified oneself with one ’s organization, and then tends to do more cooperative behaviors. Based on these results, we can conclude that it might be important to differentiate the network type and to consider psychological linkages when explaining cooperative behavior. Moreover, practically in a project team such as TV, musical, and movie production team, cooperative behavior is intrigued by instrumental relationships, not by expressive ties, so that leaders had better encourage task-oriented communication between team members.
