Companies that wish to draw benefit from supplier resources beyond standard market offerings must actively make an effort to mobilize these resources. This task has been a major topic of interest in the management literature, but the continued reported problems of companies attempting to influence suppliers suggests that the knowledge of this challenge is yet inadequate. The purpose of this paper is therefore to establish a research agenda on supplier resource mobilization that can improve this knowledge. To fulfill the purpose we review the management literature and identify the most prevalent theoretical perspectives. This review, synthesis, and resultant discussion allow us to propose that future research should look closer at the resource activation process on the supplier side, the role of the buyer-supplier relationship in resource mobilization, and the approach of the buying company in supplier resource mobilization.
