This research explores s-commerce users' intentions to purchase and to share knowledge by incorporating 'attitudes toward persuasion attempts,' 'ease of use,' and 'perceived usefulness' into a social exchange theory model. A survey using an on-site purposive sampling technique was used to recruit the respondents, and an interception technique was used to approach the consumers. A total of 471 Korean consumers participated in this research. Based on 471 Korean social-commerce users, our results reveal that social exchange belief factors and a site's usability affect user satisfaction, which subsequently affects users' intentions to purchase and to share knowledge. In addition, attitudes toward persuasion attempts moderate the effect of satisfaction on users' purchase intentions.
