Yes / While the importance of s-commerce is implicitly recognized, inconsistencies in extant empirical research pose significant challenges. Based on perspectives from trust, social presence, and socio-technical theories, this study develops an integrated model of the factors that influence intention and use behavior, with particular attention to the role of trust in s-commerce. The model is tested using meta-analytic structural equation modeling techniques on 201 observations from 83 s-commerce studies. Implications for research and practice are discussed.
