In Germany, more and more online services are emerging that enable the sharing or joint use of products between private individuals - so-called peer-to-peer (P2P) sharing. This report presents empirical findings on P2P sharing. It shows how P2P sharing is perceived and evaluated by users and which motives are decisive for its use. It also provides insights into usage behavior. The findings are the result of four quantitative surveys in different consumption areas. Users of the P2P sharing services Drivy (private car sharing), flinc (carpooling), Kleiderkreisel (clothing sharing) and Wimdu (apartment sharing) were surveyed.
