摘要：With the development of the Internet, the use of social networks has become more and more important in team management. The purpose of this study was to investigate the impact of social networks use on team performance and the moderating role of emotional contagion plays in this relationship. 80 college students from 20 innovation and entrepreneurship teams completed questionnaires on team social networks use scale and team performance scale, and then performed team tasks. Three video clips were used as emotionally induced materials. Results showed that the use of social networks can positively predict team performance, and that positive emotional contagion also has the predictive effect. Critically, emotional contagion acts as a moderator in the relationship between the use of social networks and team performance. Specifically, under the condition of positive emotional contagion, the high-level use of social networks can positively predict better team performance; under the condition of negative emotional contagion, there is no significant difference in team performance at different uses of social network service levels. These findings suggest that managers should pay more attention to the dissemination of positive emotional information in social networks to improve team performance.
