Based on the motivation of the social service users at home and abroad, this paper analyses mobile SNS user’s perceived value including social value, information value and entertainment value. Drawing on perceived value and expectation-confirmation theory, the concept model of SNS user continuance intention is constructed. Using structural equation model，an empirical analysis on 328 mobile SNS users is carried out to test and verify this model．The result shows that social value, information value and entertainment value not only directly affects continuance intention, but also has indirect effect on continuance intention through satisfaction. carried out to test and verify this model．The result shows that social value, information value and entertainment value not only directly affects continuance intention, but also has indirect effect on continuance intention through satisfaction. Finally, the limitations of the study and future research directions are proposed.
