Historians of modern, multinational, diversified industrial economies have learned that to deduce rigid, authoritarian control of subsidiaries, especially those in foreign countries, from the fact of over-all corporate ownership from afar, often leads to very inaccurate conclusions. The case of Canadian Industries, Ltd., a diversified Canadian chemical company jointly owned by the American and British giants, Du Pont and Imperial Chemical Industries, Ltd., reveals that a remarkable degree of independence was retained by the Canadian subsidiary even in such globally important policy matters as diversification, entry into new geographic areas, transfer of technology, and inter-company pricing of materials. Transnational ownership of industrial facilities, in short, produced advantages that were shared by both headquarters and local enterprises, leaving most of the anti-multinational movement to be explained as simpleminded nationalism.
