||The triad regions, Japan, the United States, and the European Union, together are the homes of almost all of the world\\\'s largest 500 corporations. They account for a large majority of world exports. They provide most of the world\\\'s outward flows of foreign direct investment, and in addition, they are the recipients of most of inward FDI flows. However, they are very different, in firm structure, in regulatory environment, and in the relations between private firms and government agencies. Dealing with them as competitors, customers, suppliers, or partners requires international managers to be aware of these differences and to vary their strategy accordingly. This unit compares the structure and operations of triad firms, and the ways that government agencies frame the operating environment in each region. The unit initially looks at the ways firms in each region seek competitive advantage, and how governments have supported them. It then examines a series of cases where firms have moved from their home region into another, at the ways in which they have attempted to transfer their competitive advantage, and at the reasons for their successes and failures. In addition to the specific knowledge of the habits and tendencies of Japanese, United States, and European firms, the techniques of analysis developed in this unit are applicable to a wide range of competitive situations across the global economy.
