The concept of a sharing economy, as part of a wider collaborative economy concept, is among the most important economic and technological trends that will influence socioeconomic development in the future. Interest in using the opportunities offered by sharing platforms is increasing; hence, the subject is a current and important issue. Confidence in technology, service providers and application providers is a key issue when making decisions about using such solutions. The aim of the paper is to examine the level of trust in sharing economy business models considering two groups of factors, trust in people and in technology, among several demographic groups. The paper has an empirical character and the results are provided on the basis of a survey conducted in Szczecin, Poland, with 403 respondents who are current and potential users of sharing platforms. The obtained results show that platform management requires more attention focused on building mutual trust networks among participants rather than strengthening the confidence in using the technology.Sustainability 2019, 11, 6838 2 of 26 supply side.

Although there are papers concerning the impact of social referrals and technological enablers on trust in sharing platforms [8], our research differs in factors that characterize each of these groups. The paper has an empirical character and the results are provided based on a survey conducted by the authors. The analytical part of the study is based on answers given by 403 respondents from Szczecin, Poland. The statistical analysis of the results was conducted with the use of basic statistics measures, as well as Cronbach's alpha measure, nonparametric Kolmogorov-Smirnoff test, Kruskal-Wallis test, centre of gravity (CoG), histograms, box plots, and radar charts.The paper is divided as follows: First we introduce the idea of the sharing economy as a business model that can act for sustainability, then we provide a literature review on trust in the sharing economy. After that, we explain our research procedure and methods, discuss the main findings and provide managerial implications for sharing platforms.
