Cross-institutional collaboration networks in tourism and hospitality research

This paper examines cross-institutional collaboration in tourism and hospitality research using a co-authorship network model based on papers published in six top-tier tourism and hospitality journals over the past 20 years. Data analysis reveals that multi-author, multi-university studies are the fastest-growing type of authorship structure in tourism and hospitality research. We use several network measures to evaluate the intensity of research collaboration among academic institutions in tourism and hospitality disciplines. Institutions with tourism and hospitality programs worldwide are ranked according to their centricity in cross-institutional research collaboration networks and categorized according to their characteristics in collaboration. The empirical analysis shows significant associations between research performance and a university's centricity position in cross-institutional research networks. Through advanced social network analysis, this study provides new insights into institutional collaboration in tourism and hospitality research over the past two decades. (C) 2012 Elsevier Ltd.
