More and more interpersonal communication is carried online. In this study, we distinguished two information sharing states: public sharing and private sharing, and identified the factors that influence users’ states. Using communication privacy management theory (CPM), we developed a framework to explain the effects of context, motivation, risk-benefit ratio, and some additional characteristics on users' choice of the information sharing states in the context of enterprise social networks (ESNs). The results show that most metrics of context, motivation and risk-benefit ratio are significantly influence the information sharing states. As the first empirical study to classify and compare the information sharing states among users on ESNs, our study enriches the existing literature and opens new avenues for researchers and social networking platforms.
