EFFECTS OF INTERNATIONAL DIVERSITY AND PRODUCT DIVERSITY ON THE PERFORMANCE OF MULTINATIONAL FIRMS.
研究美国大型工业跨国公司的国际多样性和产品多样性如何影响企业绩效，发现产品多样性与绩效呈二次关系，而国际多样性影响较小。
This study examined the relationships among international diversity, product diversity, and firm performance. For a sample of large American industrial multinational enterprises (MNEs), it showed a consistent quadratic relationship between product diversification and MNE performance but minimal performance differences across different measures of international diversity. Analysis of the interactions of international diversity and product diversity indicates a weak effect from increasing internationalization on the performance effect of product diversity.
