II Brief Introduction
Products have a limited market life PLC four stages (Marketing) location of production shifts dynamic development of comparative Advantage Theory based on Technological Gap Theory.
The Product Life-Cycle Theory
The product life-cycle model of trade (PLC) (PCT)
Product Cycle Theory
Why?
Consider: “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, JR
To explain the causes of 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.

Stage III: The Standardized Product
III Stages of the Product Cycle
Stage I: The New Product Stage II: The Maturing Product Stage III: The Standardized Product Completely standardized; Technology accounts less (LDC) Profit margins are thin, and competition is fierce. Labor-intensive (unskilled)

III Stages of the Product Cycle
Stage I: The New Product ----Innovation highly skilled labor; capital for R&D; location non-standardized; high cost; monopolize Technology-intensive No international trade happens

PCT: Dynamic understanding
As the product life cycle stage changes, the determinants affecting the comparative advantage is changing. Therefore, different types of countries can be in different stages of comparative advantage. technology-intensive capital-intensive labor-intensive (unskilled)

I Background
Technological Gap Theory (技术差距论)
Trade maybe caused by technical changes and developments. “Particular technical changes originate in one country, „comparative cost differences‟(比较成本差异) may induce trade in particular goods during the lapse of time taken for the rest of the world to imitate one country‟s innovation. ” ——International Trade and Technical Change
Technological development of a new product generally has three stages: new product stage, the stage of maturity and standardization.

II Brief Introduction
Increasingly standardized flexibility in design; manufacturing declines; competitors develop; (prices and profit margins) Loses market or invests abroad trade and investment are intertwined Capital-intensive
A product’s life World trade ——Raymond Vernon Manufactued countries
Import & Export trade Technology transfer FDI (Foreign Direct Investment)

IV Trade Implications of the Product Cycle
A. The product is initially designed and manufactured in the U.S. B. As the product moves to the maturing product stage, production expands to other advanced countries. C. The standardized production stage sees the comparative advantage of production and export shift to less developed countries.
