Cross-Border Electronic Commerce (Cross-Border Electronic Commerce) refers to an international business activity in which trading entities in different customs territories reach transactions and make payments and settlements through e-commerce platforms, and deliver products and complete transactions through cross-border logistics.

As the technical basis for promoting economic integration and trade globalization, cross-border e-commerce has very important strategic significance. Cross-border e-commerce has not only broken through the barriers between countries (and regions), making international trade move towards “borderless trade”, but it is also causing great changes in the world’s economic and trade. For enterprises, the open, multi-dimensional and three-dimensional multilateral economic and trade cooperation model constructed by cross-border e-commerce has greatly broadened the path to enter the international market and greatly promoted the optimal allocation of multilateral resources and mutual benefit and win-win results among enterprises; for consumers, cross-border e-commerce makes it very easy for them to obtain information about other countries (or regions) and buy high-quality and low-priced products.
