文摘Through his attempt to clarify justifiable economic circumstances where a policy of globalization and/or a policy of national isolation is proven valid, the author reveals in this thesis that there are two such economic phases： an economy where the theory of comparative advantage, proposed by David Ricardo, is applicable, and an economy where the theory is not applicable. The author applied his original approach to prove the validity of Ricardo＇s comparative advantage theory, and found that the theory can be justified only when a macro economy is in the thetical economic phase, where a policy of globalization is effective. It is a necessary and sufficient condition for the theory to be valid. In other words, Ricardo＇s theory of comparative advantage is not applicable when a macro economy is in the antithetical economic phase, where a policy of national isolation, instead of that of globalization, is valid. The thetical economic phase and the antithetical economic phase of a macro economy, referred to in this thesis by the author, are a version of an expression quite common in OR （operations research）.
