A June 2018 study,[3] using bibliometrics and network analysis, analyzed the evolution of scholarly research on collaborative consumption, and identified that this expression started in 2010 with Botsman and Rogers' (2010) book "What's mine is yours: The rise of collaborative consumption". The number of studies published on the subject then increased exponentially in 2014. Furthermore, there are four clusters of research: 1) exploration and conceptualization of collaborative consumption; 2) consumer behavior and marketing empiricism; 3) mutualization and sharing systems; 4) sustainability in the collaborative economy. The analysis suggests that this last cluster was under-researched in contrast to the three others, but has started to increase in importance since 2017.
