S. Tallman et Tt. Li, EFFECTS OF INTERNATIONAL DIVERSITY AND PRODUCT DIVERSITY ON THE PERFORMANCE OF MULTINATIONAL FIRMS, Academy of Management journal, 39(1), 1996, pp. 179-196
This study examined the relationships among international diversity, p
roduct diversity, and firm performance. For a sample of large American
industrial multinational enterprises (MNEs), it showed a consistent q
uadratic relationship between product diversification and MNE performa
nce but minimal performance differences across different measures of i
nternational diversity. Analysis of the interactions of international
diversity and product diversity indicates a weak effect from increasin
g internationalization on the performance effect of product diversity.
