A parallel multiple mediator model of knowledge sharing in architectural design project teams

The demystification of the underlying mechanism for architectsʹ knowledge sharing behavior in a project team context is of importance to better appreciate the behavior in a theoretical sense and for effective managerial intervention in a practical sense. However, most studies of knowledge sharing mechanism in current literature focus on the simple mediation. The likelihood of multiple mediators for knowledge sharing is yet to be investigated. To bridge this gap, structural equation modeling is applied to test the parallel mediation of team-based self-esteem and team identification between two types of trust and knowledge sharing with survey data. It is found that the relation between affect-based trust and knowledge sharing is completely mediated by team-based self-esteem and team identification. The model implies that project managers should pay attention to the cultivation of membersʹ team-based self-esteem and team identification. Special measures should also be taken to build and strengthen the affect-based trust.
