In recent years, with the improvement of Internet infrastructure and the construction of a global logistics network, cross-border e-commerce has entered a stage of rapid development, and the scale of transactions has been expanding, becoming a vital force in the development of my country’ s foreign trade. As a major coastal economic province in my country, Guangdong Province has taken the lead in developing cross-border e-commerce by virtue of policy dividends, location advantages and its own sound foreign trade foundation, and has achieved remarkable achievements. Although the development space of cross-border e-commerce in Guangdong Province is good and the momentum is strong, as an emerging e-commerce model, its development is not smooth sailing, and there are still some hidden worries under the appearance of prosperity. From the perspective of healthy and sustainable development, Guangdong cross-border e-commerce should face up to its lack of independent brands in the international market, imperfect cross-border e-commerce logistics system, insufficient policy guidance strategies, imperfect payment system, and professional cross-border e-commerce talents. This paper will propose corresponding optimization measures based on these problems, in order to improve the development level of cross-border e-commerce in Guangdong Province, and provide certain inspiration for the development of cross-border e-commerce in other provinces in my country.

Integrated circuits are the cornerstone of the development of information and communication technology industries in various countries, and to a large extent affect the development of the future technological industry revolution, and are known as “industrial food”. With the transfer of the global integrated circuit industry chain, emerging economies in East Asia represented by China and South Korea occupy a core position in the global integrated circuit trade. In recent years, although the scale of China’s integrated circuit trade has expanded rapidly, it has been in an unbalanced state for a long time, and the trade deficit is extremely high. The domestic demand for high-end integrated circuits can only be met by imports. The development of my country’s integrated circuit trade is large but not strong. Thanks to the financial support and preferential policies of the Korean government, in the 1980s, Korean integrated circuit companies took the lead in breaking through the international technology of memory integrated circuits. After that, the Korean government developed other integrated circuit products on this basis. Export of foreign exchange earning products. In order to measure the gap between China’s IC trade international competitiveness and South Korea more accurately. Next, a literature study is conducted on the comparative analysis of the development status of integrated circuit trade between China and South Korea. It was found that the development of South Korea’s integrated circuit industry was later than that of China, but the latter came ahead.
