Product Life Cycle THEORY (國(guó)際貿(mào)易-英文)產(chǎn)品生命周期理論

1、The product life-cycle model of trade (PLC) () “The model (PLC) claims that many products go through a trade cycle, during which the United States is initially an exporter, then loses its export markets and may finally become an importer of the product. ”Louis T. Wells, JR23 Factor Endowment Theory

To explain the causes o

3、f international trade and trade patterns based on the changes in technology ,in 1961, the U.S. economist M. V. Posner proposed the Technological Gap Theory and gave an explanation. 4Technological Gap Theory (技術(shù)差距論) Trade maybe caused by technical changes and developments. “Particular technical chang
