Mapping Hotspots and Emerging Trends of Tourism E-Commerce: A Multidisciplinary Perspective

Tourism e-commerce is a multidisciplinary research area that involves tourism management and e-commerce. This paper provides a review of 1960 scientific studies published over the past two decades (1999-2018). This study presents a multidisciplinary comparative study, namely, a systematic review of tourism e-commerce, aiming to provide a reference guide for researchers. Under the methodological framework of a domain analysis, this paper analysed the scientific outputs and visualized the co-cited references, burst keywords, keyword co-occurrences and topic characteristics of journals. The results show that the tourism management discipline represents the main body of tourism e-commerce research and that this research demonstrates a rapid growth trend consistent with overall research. There are two main clusters of representative co-cited references in the tourism management discipline. However, in the e-commerce discipline, the distribution of co-cited references is scattered, lacking obvious cluster characteristics. The keyword co-occurrences in both disciplines present four themes, including network and information technology, consumer behaviour and social media as common themes. Tourism management journals can be divided into two categories, while e-commerce journals can be divided into three categories. Overall, the findings of this study can benefit researchers and practitioners.
