Now, international economy and trade are playing an increasingly important role in the national economic development.

Foreign language proficiency is very important for both professional theoretical study and practical activities related to practice. So students who apply for this major should be interested in foreign languages. Secondly, because international economy and trade belong to the economic discipline, it involves not only the theoretical knowledge of marketing, international finance and commodity science, but also statistics, mathematics, geometry and other knowledge. A certain level of mathematics is an important factor to learn this major well, especially for students interested in the study of international economy and trade theory. If you are interested in foreign trade and are willing to engage in foreign trade management, consultation, policy or theoretical research, then international economy and trade are your best choice.

Professional code of international economy and trade: 020 102. Second, develop professional education. As a professional discipline, international trade is gradually established and improved with the development of international trade practice, which evolves with the development of human social productivity, science and technology and social division of labor. So in the final analysis, the major of international trade is also the inevitable product of the development of human history. As far as the fields involved are concerned, international trade is closely related to economics, finance, transportation, insurance, marketing, statistics, law, management and other disciplines. Moreover, with the development of economic globalization and the universal establishment of market economy in the world, economic exchanges between countries have gone beyond the boundaries of tangible goods trade. With the development of international investment, the form and content of international trade have undergone profound changes, which makes international trade as a discipline must accommodate more professional disciplines, absorb the knowledge and information necessary for practical development in the process of knowledge economy, and fully reflect the needs of development in the curriculum. As far as its main course content is concerned, the major of international trade mainly includes two parts: one is international trade theory and policy, and the other is international trade practice. As a specialized course, international trade has not entered the classroom for a long time, and it has only a history of several decades. However, the study of international trade theory and policy has a history of more than 200 years. Nowadays, all the popular economics are western economics, which is also due to the fact that capitalist relations of production germinated earliest and developed most fully in western countries, and the theoretical soil is practice. The fully developed western capitalist economy has promoted the formation and perfection of economics, and the theory of international trade is accompanied by the germination of capitalism and the industrial revolution. Adam Smith,/kloc-a British economist in the 0/8th century, is known as the "father of economics". It was he who first put forward the core question of international trade theory, "Why do you want to conduct international trade", and made the answer "the principle of absolute superiority" that no one can overturn so far. His book "Research on the Nature and Principle of National Wealth" is still a treasure house in the field of economics, and it still has important practical significance today after more than 200 years. His theory was perfected by another British economist, david ricardo, and formed the theory of comparative advantage, which marked the establishment of the core theory of international trade. Many economists in later generations only did some tinkering work on this theory without any fundamental breakthrough. In addition, international trade theory also includes international division of labor, international value, multinational company theory, infant industry theory, foreign trade multiplier theory and so on. The core of these theories is also to explain the benefits of international trade. When an economic phenomenon appears, in order to make it reasonable and meet the interests of some or most people, a theory must appear to prove its correctness from one or several aspects, thus exerting influence on national policies based on this theory. Because of the particularity of the scope of international trade, it is certain that a sovereign country and another sovereign country have common interests in trade.
