The purpose of this paper is to study the influence of the shared mental model (SMM) on team innovation performance (TIP) by exploring the moderating effect of emotional infection (EI).The Credamo platform was used to conduct a questionnaire survey on Chinese teams participating in collaborative innovation projects, and 198 valid samples were collected for the research. The authors apply confirmatory factor analysis to test the reliability and validity of the constructs, structural ordinary least squares hierarchical regression model to verify the hypothesis. The results show that both the collaborative shared mind model and the task-based shared mind model have significant positive effects on team innovation performance. Positive emotion infection can regulate the relationship between the collaborative shared mind model and team innovation performance, but has no significant moderating effect on the relationship between the task-based shared mind model and team innovation performance. Negative emotional contagion not only negatively moderates the relationship between the collaborative shared mental model and team innovation performance, but also negatively moderates the relationship between the task-based shared mental model and team innovation performance.
