The report of the 20th National Congress of the Communist Party of China put forward a series of important requirements around "accelerating the construction of a new development pattern and striving to promote high-quality development", including "enhancing the endogenous power and reliability of the domestic big cycle and improving the quality and level of the international cycle". This is also a key point emphasized at the Central Economic Work Conference held not long ago. In order to better coordinate domestic circulation and international circulation, we should take multiple measures to improve the quality and level of international circulation while attaching great importance to domestic circulation. Important role High quality development reflects the development of new development concepts. From this perspective, improving the quality and level of international circulation can play an important role in promoting high-quality development. It is conducive to promoting innovative development. At present, China's basic research and original innovation are constantly strengthened, but there is still a big gap between some areas and developed countries. Improving the quality and level of international circulation is conducive to learning, drawing on and introducing world advanced technology, optimizing the allocation of innovative resources, and accelerating the realization of self-reliance in high-level science and technology. It is conducive to promoting coordinated development. By improving the quality and level of international circulation, we can optimize the allocation of production factors globally, form an open pattern of interaction at home and abroad, and mutual aid between east and west, plant development advantages, and accelerate the complement of weaknesses, thus realizing the coordinated development of China's industries, regions and other different dimensions. It is conducive to promoting green development. Improving the quality and level of international circulation will further promote China's development of digital trade, import and export of pollution-free and low energy consuming products, promote the construction of the green "the Belt and Road", promote China's green development to a new level, and provide help for the majority of developing countries to accelerate the green and low-carbon transformation. It is conducive to promoting open development. Improving the quality and level of international circulation means that China's level of participation in the international market is getting higher and higher. A virtuous circle is formed in promoting high-level opening up, and the linkage effect between domestic and international markets and resources is enhanced, which can not only open up new space for China's economic development, but also promote the construction of an open world economy. It is conducive to promoting shared development. With the improvement of the quality and level of international circulation, "Buy the world and sell the world" is more unimpeded, the flow of goods and elements of enterprises is accelerated, and economic benefits are rapidly improved. Residents can enjoy high-quality and inexpensive goods and services around the world, so that all regions and enterprises can achieve win-win and shared development, so that more and more equitable development results can benefit all people. Multiple advantages Through the development since the reform and opening up, especially since the 18th National Congress of the Communist Party of China, China has a broad domestic and international market, a strong industrial chain supply chain, a solid material foundation, and many advantages and conditions to improve the quality and level of international circulation. First, it has the advantage of openness in a wide range of areas. China has become a major trading partner of more than 140 countries and regions, and has continuously maintained its position as the largest country in the world trade in goods, the second largest in the world trade in services, and the world's leading in attracting foreign capital and foreign investment, laying a solid foundation for improving the quality and level of international circulation. Second, the supply advantage of global public goods. China has actively participated in the reform of the WTO, provided China's plans on issues such as promoting the recovery of the world economy, and put forward the initiative of jointly building the "the Belt and Road".
