统一国际贸易理论的分析框架

通过比较自亚当·斯密以来的不同发展阶段的国际贸易理论分析框架可以发现，虽然不同理论的基础假设、逻辑演绎的原则与思想以及结论不同，但可以使用一般化的二元平均成本函数c=c（w，r，β，q，m）对不同理论的基本分析工具进行统一，这对于加深理解现实的国际贸易模式与相应的国际贸易理论，把握理论今后的发展趋势，实现理论创新与制定高效的贸易政策都具有重要的意义。

The Unity of Analysis Frameworks of International Trade Theories

By comparing the analysis frameworks of the international trade theories in different development stages since Adam Smith, it can be found that although different theories have different fundamental hypotheses, logical deductive principles and i- deas and theoretical conclusions, the basic analysis tools in different theories can be unified with a general dualistic average cost function c = c （w, r,β, q, m） , which has important significance for understanding the international trade patterns in the world and the corresponding international trade theories, grasping theoretical development trend in the future, realizing theory innova- tions and establishing efficient trade policies.
