A Review on the Recent Development of Comparative Advantage Theory

With the development of international economy,the theory of comparative advantage continues to expand in several aspects by relaxing traditional assumptions,which reflects new vitality from multiple angles,showing an increasingly strong inclusion and comprehension.This paper systematically reviews recent researches on the theory of comparative advantage.It will review theoretical and empirical studies from the aspects of trade motivation,trade pattern and trade welfare,which expand traditional theories or find new sources of comparason.Our survey concludes that the theory of comparative advantage is still the cornerstone of trade theories,and new theoretical studies follow the basic logic of the traditional theory.They constitute an organic supplement to the traditional theory,and provide rational explanation for constantly updated international economic practices.
