Knowledge management of a new product development project team is critical for a firm's competitive advantage, and incentive mechanism is one of the most effective knowledge management drives. In this paper, we examined the effects of non-financial incentive and team-based financial incentive on knowledge management performance in China and identified the moderating effects of knowledge attributes (codifiability and teachability). Our findings indicate that non-financial incentive and team-based financial incentive have positive effects on knowledge management performance. Codifiability and teachability enhance the team-based financial incentive–knowledge management performance relationship. Finally, implications for research and practice are discussed.
