经济理论是实践经验的高度概括,而经济模型则是经济理论的简明表达。用经济模型来分析和研究问题,有助于我们更直观,甚至更具体地认识对象。经济模型有两大应用方向,其一为经济理论研究,其二为实际经济管理。在此,我们试对中国的对外贸易理论模型及其应用作一初步的探讨,用现代国际经济学方法,从比较新的角度来考察和分析中国的对外贸 Economic theory is a high-level summary of practical experience, while economic models are concise expressions of economic theory. Using economic models to analyze and study problems helps us to be more intuitive and even more specific about the subject. The economic model has two major application directions. One is economic theory research, and the other is actual economic management. Here, we try to make a preliminary study of China’s foreign trade theory model and its applications. We use modern international economics methods to examine and analyze China’s foreign trade from a relatively new perspective.
