Knowledge sharing, along with its potential predictors, has been a popular research topic. This research extends prior research by examining potential predictors of knowledge sharing together within a more comprehensive model with two additional contexts: the type of recipient of the knowledge is the recipients of intraorganizational broadcast media, and the type of knowledge sharing behavior (full knowledge sharing and partial knowledge sharing). The results of this study suggest that what predicts knowledge sharing behaviors depends on the type of knowledge sharing behavior when considering why people share their knowledge through intra-organizational broadcast media. We explore theoretical implications and future research avenues.
