The EU is the world’s largest trade group, occupying an important position in the world trade in goods and services, especially in the field of service trade. The EU trade in services exports and imports are higher than the United States and Japan, and the EU is the world’s largest capital output and input group, and the world’s largest foreign aid providers. With the deepening of the European integration process, Europe’s position in the world economy and trade is on the rise. Therefore, the EU’s trade policy has increasingly become the focus of attention. From the vertical point of view, research directions can be divided into trade in goods policy, trade in services policy, international direct investment policy, trade-related intellectual property policy four field. In this paper, the four vertical areas are illustrated as the focus of the study.
