Theoretical activity in sustainable tourism research

•Assesses how sustainable tourism articles advance theoretical understanding.•Identifies strategies for theoretical work in sustainable tourism studies.•In the past theorisation was considered limited in tourism research.•Uses a typology of strategies for theoretical work in sustainable tourism.

There is growing recognition in tourism and sustainable tourism research of the need for a fuller engagement in theoretical activity. The paper examines how different research strategies in recent articles on sustainable tourism have advanced theoretical understanding in this research field. The articles advance thinking through ideas and concepts connected with political ecology, mobilities, transition pathways, and behavioural and systems change. They are evaluated using a typology of research strategies associated with theoretical work, using a broad perspective on this work. The research strategy typology was developed for the paper, and it is explained and illustrated. While the papers on sustainable tourism use a range of strategies associated with theoretical activity, there is only limited engagement with “big” social theories.
