Abstract:Some scholars have proposed that economies grow by upgrading the commodities they produce and export. Product space theory holds that the export structure is determined by a country’s factor endowment and technological level, proposing the revealed comparative advantage (RCA) to analyze the specialization on commodities for countries. With the development of global trade, the network of multilateral trade relations has become increasingly hierarchical and complex. It would, therefore, be valuable to identify general patterns across countries of upgrading the commodity structure in the evolution of their participation in global trade. This paper shows that a typical pattern of change in the dominant types of foreign trade occurs when an economy has grown to a certain scale. With economic development, the advantages of high-technology commodities in trade gradually become more prominent.
