As a killer application of the mobile Internet, location-based services (LBS) have been popular among users. However, due to the collection and utilization of users’ location information, LBS have raised users’ privacy concern, which may negatively affect their usage. From the perspective of perceived justice, this research examined LBS users’ privacy concern and continuance usage. Perceived justice includes three dimensions: distributive justice, procedural justice and interactional justice. The results indicated that perceived justice has significant effects on privacy concern, satisfaction and flow. These three factors determine continuance usage. The results imply that service providers need to improve users’ perceived justice in order to mitigate their privacy concern and facilitate their continuance usage of LBS.
