The importance of resources as an essential component in value co-creation processes is core to multiple perspectives in management and marketing. These include the Resource-Based View, Resource Integration within Service-Dominant Logic (S-DL), Resource Dependence Theory, Resource Advantage Theory, and Resourcing. In this Editorial we compare Resource Interaction in Industrial Marketing and Purchasing (IMP) with these other perspectives, stressing both differences and complementarities. The comparison includes an explanation of why Resource Interaction in IMP is unique when utilized to explain the dynamics of change in business networks. We also introduce and synthesize seven new articles included in this Special Issue, all of which combine Resource Interaction in IMP with other theoretical perspectives in addressing themes such as supply chain management, entrepreneurship and innovation management. We conclude with a proposed agenda for further research, which provides extensive suggestions for underexplored empirical and conceptual themes.
