Abstract:As one of the important means of enterprise empowerment, structural empowerment will form a normalization mechanism once it is implemented, which will continuously and effectively affect the innovation behavior of the team. Seeing that there are few studies on team psychology and organizational empowerment in the current research on enterprise empowerment, starting from structural empowerment theory, and combined with triadic reciprocal determinism theory, this paper introduces team psychological empowerment and knowledge sharing as mediating and regulating variables respectively to build a structural equation model, and uses Amos, SPSS and other tools to analyze data and test hypothesis. The results show that structural empowerment and its four elements(information, resources, support, opportunities ) have a significant positive effect on team innovation behavior, team psychological empowerment plays a partial intermediary role between structural empowerment and its four elements and team innovation behavior, knowledge sharing reversely regulates the relationship between structural empowerment and team innovation behavior. Finally, the paper proposes that enterprise managers should pay attention to the structural empowerment effect, and improve team innovation by caring about the psychological state of employees and creating a knowledge sharing atmosphere.
