The Study of Multinational Corporations¡¦ Knowledge Management ABSTRACT In order to look for lager space of growth and subsistence, Taiwanese corporations inevitably made direct investments in foreign countries and became members of worldwide multinational corporations (MNCs). According to their international expansion, the sources and distributions of these MNCs¡¦ resources and knowledge would not be limited by the boundaries among countries but be allocated effectively through two dimensions, Global Integration and Local Responsiveness. By twelve Taiwanese multinational corporations case study, the global integration and local responsiveness of multinational organizations¡¦ knowledge, the implementation situation of Knowledge Management, and the role of Human Resources Management while implementing Knowledge Management were all observed and discussed in this study. The proposition concluded by interviewing high-level managers of sample corporations are as follows: Proposition 1: The higher industrial technique maturity of multinational corporations is, the higher centralization of the allocation of corporations¡¦ resources and knowledge will be. Proposition 2: If the industrial technique maturity of multinational corporations is higher, explicit knowledge will be transferred across countries more than tacit knowledge. Proposition 3: The longer product life cycle of multinational corporations is, the more global integration ability of knowledge innovation strategy will be emphasized. Proposition 4: The higher local responsiveness need of multinational corporations¡¦ knowledge innovation strategy is, the higher ratio of value chain distributed in foreign subsidiaries will be. Proposition 5: The higher local responsiveness need of multinational corporations¡¦ knowledge innovation strategy is, the higher ratio of local employees hiring will be. Proposition 6: The more explicit knowledge of organization has, the more information technology infrastructure will be needed to implement knowledge management. The more tacit knowledge of organization has, the more important the tacit system will be, such as organizational culture, to implement knowledge management. Proposition 7: The corporations in technique growing industry will do knowledge processing in interactive way, and design the organization by commitment-base. Proposition 8: The role of human resources management will be more strategic during the early stage of knowledge management implementation. Proposition 9: If both of global integration and local responsiveness need of corporations¡¦ knowledge innovation strategy is required, the coordination and control role of human resources management will be more important.
