BYOD, which allows employees to bring their own mobile devices to work and connect into the corporation network, has been increasingly implemented by numerous organizations and corporations. Companies expect to save cost as well as increase productivity and employees’ morale through BYOD implementation. Hence, it is critical for companies to understand how BYOD affects organizational performance. Addressing on gift economy and cognitive evaluation theory, this study indicates the gift nature of BYOD and builds up a cross-level research framework which indicates two aspects of BYOD - informational aspect and controlling aspect. When informational aspect is perceived by employees, they will return positive outcomes, thereafter increase productivity and morale. In contrast to controlling aspect, negative outcomes will be returned and then decrease productivity and morale. A two-step mixed method approach will be conducted to test proposed research framework.
