Abstract: Recognizing the importance of involving suppliers in the new product development (NPD) process, extensive studies have examined this issue at a buyer–supplier dyadic level. However, how supplier involvement leads to better NPD performance is not clearly explained. Additionally, extending the dyadic relationships to triadic relationships and addressing how to manage the two competing suppliers with fair conduct remains unexplored. To answer these questions, this study developed a conceptual model theorizing the role of supplier involvement, information sharing, and justice in the NPD process within a buyer–supplier–supplier triadic relationship. Based on survey data collected from 200 U.S. firms, Structural Equation Modeling is used to test the hypothesis. The results first confirmed the criticality of involving both primary and secondary suppliers during NPD. Second, the positive effect of triadic supplier involvement on innovation performance is fully mediated by information sharing. Finally, this study explored the different roles of procedural justice and distributive justice; the results confirmed that procedural justice acts as a moderator for the relationship between triadic supplier involvement and information sharing, whereas distributive justice moderates the effect between information sharing and innovation performance. Our findings contribute to the literature of triadic supplier involvement‐new product development and relationship management. Accordingly, these findings highlight key implications for managers and policymakers.
