**Discussion:**

It is indicated that more support for knowledge sharing by top management makes it easier for employees to implement knowledge-sharing activities [27]. Other studies have also indicated the crucial role of leadership in knowledge sharing [28]. With enough support from top management, employees would be encouraged to put efforts into keeping important data safe, storing, and sharing knowledge. Consequently, firms will have a higher performance in knowledge exchange and accumulation.
