Abstract: Through questionnaire, we attempt to analyze the relationship between immoral online behaviors and social responsibility among adolescence. 676 students from 12 classes participating in the research completed three questionnaires. The results indicate that adolescence score high in social responsibility and moral identity and have only a few immoral online behaviors. Our regression analysis indicates that social responsibility can predict the immoral online behaviors. Our moderation analysis shows that symbolization of moral identity can regulate the relationship between social responsibility and immoral online behavior. Further, for students whose score on symbolization of moral identity is high, the social responsibility can predict the immoral online behavior. But, for students whose score on symbolization of moral identity is low, the social responsibility can't predict the immoral online behavior. The article concludes with the discussion about the implications of our research for moral education.

Key words: adolescent, social responsibility, moral identity, immoral online behavior
