Social network analysis in tourism

Elements such as tourists, service-oriented organizations, tourism resources, destinations and public institutions all have a role in tourism activity. If we are to understand the world of tourism, we need to examine the ties between these elements. Social network analysis (SNA) provides tourism research with a set of methods and tools that allow us to comprehend the patterns and the structures of these ties. The objective of this work is to establish how SNA is being applied to tourism, to describe its principal elements and to inquire into its potential in the development of tourism research. To do so, the articles that apply SNA research methods, published in tourism and hospitality journals, and the network of citations between their authors are all analysed. It was found that the application of SNA in tourism-related contexts is rare and very recent, although a cohesive and relevant group of authors is currently applying it. An exciting opportunity for tourism research becomes apparent with the use of SNA and future lines of research are presented in which its methods may be applied.
