It is an undisputed fact that tourism constitutes one of the key elements of the overall, especially economic, identity of the Adriatic part of Croatia. Therefore, the economic health, competitiveness, and development of tourism actors in this region are elements that form and influence potential changes in the identity of this area. In this context, various forms of cooperation between tourism (and other) entities can be observed, which, by strengthening the competitiveness and market position of tourism companies, act as an indirect factor in the identity of the space where they occur. Despite the fact that the trend of inter-organizational cooperation has been on a significant rise for many years and that tourism, by its characteristics, is generically predisposed as an economic activity within which such cooperation is a conditio sine qua non for survival and development, data and research on the prevalence and characteristics of networking in various segments of the tourism industry are actually rare. This is also true for the hotel sector, which is often identified as the basic tourism activity and a measure of the development of the tourism offer. This paper aims to bridge part of this research gap by presenting the results of research conducted on a representative sample of hotels from the Adriatic region of Croatia and to illuminate the prevalence and basic characteristics of hotel associations in the given area.
