Along with the development of information communication technology, there are more and more location sharing services on social networking platforms. Although China has the largest number of Internet users in the world, only recently users have started using location sharing services in China. In this paper, we aimed to investigate user adoption of location sharing services on social networking platforms in China. Based on UTAUT, a research model with five research hypotheses was proposed. We tested the model by analyzingcollected survey data from 200 location sharing usersin terms of structural equation modeling method. Three hypotheses were positively significant supported, while the other two hypotheses were rejected in this research. The result indicated that the behavior intention of location sharing on social networks was positively and significantly impacted by effort expectancy, social influence and usages of the location sharing services.
