Based on the inducement-contribution theory and resource-based view， it took the Chinese listed manufacturing enterprises from 2008 to 2018 as research object， and investigated the relationship among digital technology， employee participation， network centrality and enterprise innovation performance. The results show that digital technology has a significant positive impact on enterprise innovation performance， and employee participation plays a mediating role between digital technology and innovation performance. When enterprise network centrality is high， the positive relationship between digital technology and employee participation is enhanced， and the mediating effect of employee participation is also stronger. The conclusions expand the related literature of digital technology on enterprise innovation performance， and provide practical guidance for enterprise innovation.
