This article analyses the structure of trade and trade performance of the largest six OECD economies in the 1980s. The article is concerned in particular with the role of technology and innovation and the relationship between specialization in sectors of high, medium or low technology intensity and trade performance. It assesses the argument that the maintenance of international competitiveness requires the advanced economies to become internationally competitive, and to specialize, in higher technology sectors, given that there is increasing competition, especially from newly industrializing countries in low technology products. Section I considers the theoretical basis of this hypothesis; Section II assesses whether it is compatible with data on manufacturing trade performance in the 1980s.
