The far advance in computer and telecommunication technology, and the evolution of Multinational corporations (MNCs) have led to an era of global economy. While MNCs strive for competitive advantage via their global information systems, diverse barriers on transborder data flow (TBDF) work in the opposite direction. Many researchers indicated that TBDF restrictions not only affected the operation of MNCs, but also the management of international information systems. Some others argued that transborder data laws were either found too vague to follow, or unable to seriously hamper some MNCs due to their smooth relationship with local telecommunication authorities at host countries. This paper aims to investigate the context and causes of the discrepancy. The results indicated that vendor’ s support, deregulation of telecommunication restrictions, and the areas in which MNCs operated accounted for the discrepancy and thus alleviated the impact of TBDF regulations on MNCs' operation.
