Top1. Introduction
It has been universally accepted that knowledge is the most valuable asset to help to maintain the competence of the organizations (Yajiong Xue, Huigang Liang et al., 2012; Omar E. M. Khalil, Timothy Shea, 2012). O’Dell and Jackson (1998) defined Knowledge Management as making the right people get needed knowledge at the right time and helping people share and take information into action in ways that improve organization performance. Lee (2001) regards that Knowledge Management has four major processes: capturing, storing, sharing and using knowledge, and knowledge sharing is the major barrier to transforming individual knowledge into organizational knowledge (Yajiong Xue, Huigang Liang et al., 2012; Jinwoo Kima, Minyoung Kimb, & Mark-Oliver Stehr, 2012). So it attracts much attention from scholars and experts (Judith Welschen, Nelly Todorova, & Annette Mills, 2012; Viktoriya Galushko, & Richard Gray, 2012). Widely considered as a determinant of successful knowledge management, Knowledge sharing is a most important process of knowledge management (Yajiong Xue, Huigang Liang et al., 2012; Paul M. Di Gangi, Molly M. Wasko, & Xinlin Tang, 2012). Companies must keep enhancing their capabilities by knowledge sharing (Iris Reychav, Eric W. Stein, Jacob Weisberg, & Chanan Glezer, 2012). Maruta points out that people can get the needed knowledge from others by knowledge sharing, and may create new knowledge through knowledge combination (Iris Reychav, Eric W. Stein, Jacob Weisberg, & Chanan Glezer, 2012). Many researches stress the importance of knowledge sharing (Imed Boughzala, & Robert O. Briggs, 2012; Salih Yesil, 2013). Knowledge sharing and integration across different departments is a crucial capability for an organization to develop and sustain competitive advantages (Diane-Gabrielle Tremblay, & Valéry Psyché, 2012; Megan L. Endres, & Sanjib Chowdhury, 2013). Wei-Tsong Wang, Nai-Yuan Ko emphasize that knowledge sharing can lead to the whole company’s advantage, through coordination and interaction between members which can enhance the problem solving ability (Wei-TsongWang, & Nai-Yuan Ko, 2012).
