As a new form of foreign trade, cross-border e-commerce conforms to the global new wave of technological revolution. Through a comprehensive digital platform and logistics system, cross-border e-commerce has not only facilitated the international supply chain industry chain and traditional trade, but also promoted the internationalization of enterprises, becoming a new driving force for promoting China's foreign trade growth. The latest preliminary calculation data shows that in the first three quarters of this year, China's cross-border e-commerce imports and exports reached 1.88 trillion yuan, an increase of 11.5%. In the first half of this year, there were over 100000 cross-border e-commerce entities in China, more than 1000 cross-border e-commerce industrial parks, and over 1800 overseas warehouses. China's cross-border e-commerce has diversified its foreign trade market. The business of emerging economies and countries jointly building the "the Belt and Road" has grown rapidly. A number of influential international e-commerce giants have emerged, gradually establishing an efficient and intelligent international logistics distribution system, forming a relatively strong international competitiveness, and refreshing the world business landscape. The booming development of cross-border e-commerce in China is attributed to the digital dividends brought by technological innovation, the reform dividends brought by institutional opening up, and the market dividends brought by economic development. On the one hand, cross-border e-commerce is an important component of digital trade. China has continuously made breakthroughs in the field of digital technology, innovating and applying in areas such as cross-border e-commerce supply chain system, logistics, warehousing, marketing, payment, as well as AI scenarios and big data analysis. It not only accurately connects supply and demand sides, but also provides low-cost and efficient transaction experiences for all parties involved. On the other hand, China's institutional opening-up continues to deepen, with the introduction of systematic supporting policies to support the development of the cross-border e-commerce industry, the establishment of 165 comprehensive pilot zones for cross-border e-commerce covering 31 provinces and cities across the country, and effective measures taken in finance, taxation, payment, foreign exchange settlement and sales, customs clearance, etc. Through the reform of the foreign trade system, the convenience of cross-border e-commerce transactions has been improved, providing institutional innovation dividends for cross-border e-commerce. In addition, the advantage of a super large scale market also provides broad space for the development of cross-border e-commerce. China has been the world's largest online retail market for 11 consecutive years and also the world's largest B2C cross-border e-commerce trading market. It should also be noted that there are still many problems in the development of cross-border e-commerce in China, such as inadequate supervision, incomplete after-sales service system, insufficient intellectual property protection, and insufficient financing support. Comprehensive measures should be taken to solve these problems. Improve policies and regulations for the development of cross-border e-commerce.
