Since this year, domestic e-commerce enterprises have taken more frequent trips to the sea, and Internet companies have accelerated their deployment of overseas businesses. In the context of the gradual fading of the dividend of domestic Internet traffic, the overseas market is regarded as the next growth point of China's e-commerce, and it has become a common understanding that the export cross-border e-commerce market has broad prospects. The current global development trend is undergoing tremendous changes, forming an internal tension: on the one hand, with the adjustment of international division of labor, the emergence of new Internet technologies and the flow of transnational capital, the pace of economic globalization is further accelerated; On the other hand, international trade disputes are frequent, trade protectionism is on the rise, and economic globalization is countercurrent. At the same time, the epidemic spread, trade frictions, unilateral politics and other factors led to the shutdown of some enterprises and supply chain disruption. Thanks to a series of powerful and effective measures to prevent and control the epidemic and stabilize the economy, China has become a powerful engine of the global economy during the epidemic period. Compared with traditional forms of international trade, e-commerce can benefit more enterprises during the epidemic period due to its high flexibility and high security. On the one hand, the development of e-commerce is conducive to promoting domestic and international double circulation and promoting the exploration of e-commerce comprehensive pilot area; On the other hand, cross-border e-commerce is also conducive to promoting regional economic development by selling goods and services with regional characteristics abroad. The continuous introduction of national policies has strongly promoted e-commerce going to sea, such as the inclusive "going to sea" policies of jointly building the "the Belt and Road", the free trade zone strategy and multilateral investment agreements, which have created a more open environment for Chinese e-commerce enterprises to go global and promoted the innovative development of China's international trade. Many enterprises have responded to the guidance of national policies and stepped out of the country with the help of dividends. Since the COVID-19, cross-border e-commerce has shown a booming trend in the world. According to relevant customs statistics, in 2021, China's cross-border e-commerce import and export volume will reach 1.98 trillion yuan, an increase of 15%, including 1.44 trillion yuan, an increase of 24.5%. China's e-commerce enterprises can successfully go to the sea and gain a foothold, mainly benefiting from China's strong manufacturing industry. The supply chain of China's product manufacturing has high integrity, high efficiency, strong supply capacity, and high cost performance ratio, making China's products occupy a dominant position in cross-border trade and have strong competitiveness. Relying on competitive products made in China, cross-border e-commerce can occupy overseas markets through cost performance ratio. At present, "Sailing" e-commerce has a good development momentum, some of which can occupy the forefront of overseas e-commerce, and some enterprises' group building model is also very popular and recognized by the market. With the increasingly fierce competition of domestic e-commerce, the market will shift from blue ocean to red ocean and gradually enter the stock game. The overseas market is incremental for Chinese e-commerce. The successful domestic business model has been tested by the market and can be replicated overseas. In addition, with the continuous accumulation of "Made in China" strength, Chinese e-commerce has become an imperative choice. However, it should also be noted that Chinese brands are still weak in the industrial chain, their international competitiveness still needs to be improved, and the international market still recognizes their "low product added value". In this sense, the brand going to sea should be the test and goal of China's e-commerce going to sea and even the whole international trade industry. It is worth pointing out that China
