How does supplier relationship management affect supplier innovation contribution? Interorganizational learning and social exchange theory integrated perspectives

Mobilizing a supplier's contribution to a buyer's innovation (supplier innovation contribution) is widely considered, but the role of supplier relationship management (SRM) in this process is unclear. In this research, interorganizational learning and social exchange theory were used to construct a mechanical model in which SRM affects the supplier innovation contribution. We surveyed 305 managers or technical staff members from Chinese manufacturing firms with an influence on purchasing decisions, extensive management experience, and close supplier contact. We tested the hypothesis by processing the data using structural equation models and interaction analysis. The results show that SRM mobilizes supplier innovation contribution by increasing supplier innovativeness, enhancing supplier collaboration, and helping firms become preferred customers of suppliers. Supplier collaboration can further promote the effective use of supplier innovativeness and the role of a firm's preferred customers, helping the firm increase its supplier innovation contribution.
