The objectives of this study are to suggest useful directions for promotion of SNS tourism information service to the service providers through investigating the effect relationship between SNS tourism information service quality and the information sharing intention. To achieve the objectives, as a conceptual framework of the study, the literature on SNS tourism information service quality and information sharing intention were reviewed, and the empirical studies on the perception of the service users about the services was conducted. The findings showed that the 'easy acquisition' and 'interactivity' factors of SNS tourism information service quality have an effect on the information sharing intention. Accordingly, the service providers are required to enhance the service quality related to the information acquisition and interaction between users.
