8. Limitations and future research
Although it has new findings, this study has the following limitations that need to be addressed by future research. First, although this study concentrates on exploring the effects of organizational and technological barriers on employees’ knowledge sharing behavior at firms of different sizes, it did not address the different situations of employees who work at large firms but distributed into several small units in different locations, and those who work at large firms and have centralized management in same location. In addition, younger employees may use technology to share knowledge more than older employees. The impacts of different employee ages and the average ages at large/small firms on the research model were not discussed in this study. As such, researchers may consider differences in firm size and division location in the sampling process, as well as the ages of employees at large/small firms. Such efforts would help in making a more comprehensive assessments of the issues examined this work.
