学习曲线理论

But in the second phase , all of these theories can still be categorized into 4 kinds : dynamic comparative advantage theories , such as the new factors theories by baldwin and kenen , the life - cycle theory by vernon and hirsh , etc ; intra - industry trade theories such as product differentiation model by stiglitz and dixit , the strategy trade theory by spense , brander and krugman , and so on ; the endogenous trade theory such as technology overflow effect and learning curves theory by romer and krugman , the neo - classic trade theory by tucher and young , and the like ; and the competitive advantage theory by michael porter
在这一时期,经济学家们提出了形形色色的理论,出现了“百家争鸣”局面。基本上可以归于以下四大类型:一是动态的比较优势理论;二是产业内贸易理论;三是内生国际贸易理论;四是竞争优势理论。各个阶段的比较优势理论有其时代特点,但一个共同点是:比较优势始于成本差异,并一直没有突破成本差异,而不考虑产品的附加值。
