This article reports on a study to explore the level of dependence of small and medium-sized tourism enterprises (SMEs) in Finland on the resources of the Finnish Tourist Board (FTB). A tool to measure resource dependence was developed. The overall importance of specified resources, the level of exchange of these resources acquired from the FTB, the existence of alternative sources for similar resources, and access to them were assessed. The level of dependence of Finnish tourism SMEs on the FTB was reported to be moderate. Differences were, however, identified among different types of enterprises. The size of enterprises, their proportion of foreign guests, their marketing planning, and their cooperation with others affected the level of resource dependence. The FTB resources on which tourism SMEs were most dependent were destination marketing and marketing knowledge. Results contribute to an understanding of the role of national tourism organizations.
