Abstract: In the era of digital intelligence, scientific research team as the core of organizational innovation has important strategic significance for the long-term development of organizations. Based on the organizational support theory, and combined with the questionnaire survey data, hierarchical regression method and Bootstrap method, this study incorporates the innovation ecosystem into the driving mechanism framework of perceived organizational support to systematically explore the effects of perceived organizational support and network characteristics of the innovation ecosystem on the innovation performance of scientific research teams and their functional paths. The results show that perceived organizational support can positively predict the innovation performance of scientific research teams. The perceived organizational support has a positive effect on the network characteristics of the innovation ecosystem embedded by the superior organization of the research team, such as network relationship strength, network centrality and network heterogeneity. Network characteristics of innovation ecosystem play a mediating role in the relationship between perceived organizational support and innovation performance of scientific research team, and the mediating effect of network relationship strength is the strongest. In view of this, this study proposes that the organization should establish a team-centered service concept, strengthen the supportive behavior of the team, and actively embed the innovation ecosystem that matches its own development.
