Factors influencing knowledge-sharing intention on social network sites: An empirical study in Vietnam

This study aims to explore what factors influence Internet users' willingness to share knowledge on social network sites. With the success and popularity of social network sites such as Google + , Facebook, Line, or Zalo, people realize that collective collaboration has become the cornerstone of the website's success. More and more Internet users are using social network sites for knowledge-sharing, which is playing a vital role in developing collective and collaborative knowledge. The research model in this study is based on Reasoned Action Theory (TRA) with a sample of 310 Vietnamese Internet users. A path analysis was used to test all the hypotheses using AMOS. We found that Absorptive Capacity and Organizational Self-Esteem have a positive and significant influence on Knowledge-Sharing Attitude. However, there is no positive and significant influence of Expected Return on Knowledge-Sharing Attitude. Besides, Knowledge-Sharing Attitude expectedly has a positive and significant influence on Knowledge-Sharing Intention. It is worth noting that although Expected Return has no positive and significant influence on Knowledge-Sharing Attitude, this finding helps to prove that in such an open online environment, Expected Return becomes an unimportant predictor for Knowledge-Sharing Behavior among Internet users.
