Limited research examines the effects of interorganizational trust and interdependence on the relation-ship quality between supply chain partners in the hospitality services. It is also not well understood howthe interorganizational joint team manages the relationships between hospitality firms and their suppli-ers. Drawing on the social exchange theory and the resource dependence theory, we propose a model andhypotheses to articulate the mediation effect of joint teamwork on the relationships between interorga-nizational trust, interdependence, and relationship quality. We rigorously analyze survey data from hoteland restaurant procurement managers. Our findings confirm that interorganizational trust and interde-pendence have significant effects on joint teamwork. Meanwhile, the teamwork mediates the effectsof interorganizational trust and interdependence on relationship quality. Our work enriches the under-standing of supply chain relationships in the hospitality services, and provides meaningful insights forthe hospitality firms to manage supply chains. Finally, we conclude our work with suggestions for futureresearch.
