Project members' innovative behavior is crucial to their sustainability and successful implementation of the project. This research develops a conceptual model to explore the effect of project supervisor leadership skills on member's innovative behavior. The model is examined by a sample of 437 project members in Taiwan. The results show that project supervisors' emotional healing positively influences members' innovative behavior through affect-based trust in their supervisor and supervisor conceptual skill has an inverted-U impact on members' innovative behavior through cognition-based trust in their supervisor. This paper further discusses implications of these conclusions for additional research on the association between leadership skills and innovative behavior.
