摘要：This study identifies country and industry-level determinants of intra-industry trade (IIT) between the United States and developing countries. IIT is found to decline with greater differences in relative factor endowments. Economic size and trade orientation of the developing country influence IIT in a positive way. Distance exerts a negative effect on IIT. Results show IIT occurs in nonstandard, made-to-order, vertically differentiated, labor intensive products produced by large globally integrated industries. No support is provided for the role of scale economies in determining North-South IIT. Theoretical and empirical models of North-South trade should focus on sources of IIT related to country characteristics, vertical product differentiation based on quality differences, the degree of product standardization, and labor cost differences between the North and South.
