The intellectual structure of the sharing economy.

This study analyzes the intellectual structure of the sharing economy (SE) in the hospitality and tourism industry, starting from a sample of 189 papers. A co-citation analysis was performed on the 99 most frequently cited studies. The analysis carried out identified five clusters. These groups include the following: (i) the constituent elements of sharing, (ii) the SE and the sharing phenomenon, (iii) noncommercial website platforms and the social impact generated by sharing firms, (iv) economic impacts, and (v) some negative impacts. Each cluster is succinctly described, presenting the main theme and some subtopics. [ABSTRACT FROM AUTHOR]
