Momentous developments in the global economy over the last two decades have dramatically increased the availability of industrial investment sites and lowered the cost of relocating core activities to new countries. But how should these developments be exploited for competitive advantage? Firms face competing pressures: scale economies and the advantages of proximity push them to concentrate activities in one or only a few locations, while low wages and new markets invite dispersal across several countries. This book examines how location decisions have contributed to the global dominance of U.S. firms in the hard disk drive industry. In analyzing the industry since its beginnings some forty years ago, the book explains how American leadership in disk drives has rested on the formation of two complementary industrial clusters. Fundamental research and product development has been located almost entirely in the United States, principally California. Manufacturing has been concentrated in Southeast Asia (initially in Singapore and later in Thailand and Malaysia as well). This duality has proven key to the successful competitive position of the U.S. disk drive industry.
