Foreign‐based competition and corporate diversification strategy

Since the mid‐1980s U.S. domestic firms have faced significant increases in foreign‐based (i.e., import) competition as reductions in barriers to international commerce have resulted in markets and industries becoming increasingly global. Despite the growing and widespread importance of foreign‐based competition, the influence that such competition may exert on corporate diversification strategy is a question largely overlooked in the strategic management literature. This paper examines the impact of foreign‐based competition in a firm's core business on both the level and nature of a firm's diversification strategy at the corporate level in a panel dataset of U.S. firms over the period 1985–94. Our findings provide the first evidence that increased foreign‐based competition is indeed a statistically significant factor explaining both the reduced business‐level diversity and the increased strategic focus of U.S. firms that has been widely perceived over the past two decades.
