Sporting event networks are complex partnerships providing scope for investigation at multiple levels of analysis, including interpersonal, interorganizational, and field level. Based on an integration of the literature on interorganizational relationships, perceived organizational support, and interorganizational commitment, the paper proposes a conceptual model applicable to sporting event networks wherein perceived interorganizational support (PIOS) influences perceived interorganizational commitment (PIOC). The level of PIOS is indicated by six salient factors: trust, resources, structure, prior ties, reputation, and legitimacy.
