What drives content creation behavior on SNSs? A commitment perspective

We investigate the mind-sets driving users' content creation behavior on social network sites (SNSs) and antecedents of these mind-sets. The results of our survey of 1242 Renren users in China indicated that affective and continuance commitments are the main drivers of users' content creation behaviors on SNSs, while normative commitment has little influence on content creation behaviors. Further, informational support and emotional support from the social support perspective, reputational capital and relational capital from the sunk cost theory, subjective norm and perceived critical mass from the social influence perspective perform well as antecedents of affective, continuance, and normative commitment, respectively.
