In the past, the social network analysis has been used to explore the relationship between network structure and organization performance in alliance/cooperation network for many years. In this research, we extended the research to the co-opetition network, where the players in this network cooperate and compete with each other at the same time. The major research object is to examine if the network index that have positive influence on organizations performance in alliance/cooperation network could also have positively influence in co-opetition network. In this research, we selected baseball players trading network as our research target because the nature of player trading with other team is cooperation, but still, the teams have to compete with each other and win more games as possible. Besides of network index, we also consider team payroll’s effect on team performance and its interaction with independent variables.
The result of this research indicated not only the payroll of a baseball team has positive influence on team performance, but also influence the relationships between network index and team performance. The result indicated that in this co-opetition network, high payroll teams should involve in trading more frequently, while the low payroll team should lower the frequency of trading players. If we take payroll as different capital, the result could help us to understand co-opetition behavior of firms in different industry.
