The model of influencing factors on network community users’continuance information sharing behavior is established based on the UTAUT model and the theory of perceived value. Through the empirical research of questionnaire and Structural Equation Modeling(SEM), we use AMOS to conduct data analysis and the model applicability is tested. Results confirm that information perceived usefulness and social influence positively affect network community users’information sharing attitude, while effort expectancy has no impact on users’attitude. Meanwhile, information infrastructure perception and information sharing attitude have positive impact on network community users’continuance information sharing behavior.
