This study examines collaborative consumption networks in the context of sharing economy and discusses the role of web sites in spreading the collaborative consumption movements. 6 web sites which were determined by taking into account characteristics of the sub-systems examined under the collaborative consumption, were evaluated on a total of 57 criteria compiled from relevant studies and organized in accordance with the purpose of the research and web sites examined by content analysis. Findings related to web sites are discussed in the context of the development of sharing systems and subsytems in the scope of collaborative consumption. Some criteria observed in the study that the contents of the web sites examined represent sub-systems of collaborative consumption networks. In addition, there are elements about trust and prevalence criteria that are important for the development of the sharing movement, but the result shows that these elements need to be developed.
