We should improve laws and regulations, improve the regulatory system, strengthen the docking of rules, achieve efficient operation and mutual promotion of domestic and foreign trade, better align with the report of the 20th National Congress of the Communist Party of China on domestic and international markets, accelerate the construction of a new development pattern, and strive to promote high-quality development, It clearly requires "to organically combine the implementation of the strategy of expanding domestic demand with the deepening of supply side structural reform, enhance the endogenous power and reliability of the domestic big cycle, and improve the quality and level of the international cycle". Promoting the integrated development of domestic and foreign trade is an important measure to promote the implementation of the strategy of expanding domestic demand, accelerate the upgrading of related industries, optimize the supply and demand structure, and serve to build a new development pattern. Recently, the Ministry of Commerce announced that 9 regions, including Jiangsu, Zhejiang (including Ningbo), Fujian (including Xiamen), Guangdong (including Shenzhen), Beijing, Shanghai, Chongqing, Hunan and Xinjiang, were selected as the pilot regions for the integration of domestic and foreign trade, and were publicized to the public. Through pilot projects, we will accelerate the cultivation of a number of domestic and foreign trade integrated enterprises, form replicable experiences and models, and play a leading role in promoting the integrated development of domestic and foreign trade. In recent years, China's domestic and foreign trade integration has made great progress, and the scale of domestic and foreign trade markets is growing. In January this year, the General Office of the State Council issued the Opinions on Promoting the Integrated Development of Domestic and Foreign Trade, which made a deployment on promoting the integration of domestic and foreign trade, forming a strong domestic market, and unblocking the domestic and international double cycle. It required to improve the domestic and foreign trade integration business ability of market players, and stimulate endogenous development momentum. In May, the Ministry of Commerce and other 14 departments issued the Notice on the Pilot of Domestic and Foreign Trade Integration, and decided to take the lead in carrying out the pilot of domestic and foreign trade integration in some regions. At the same time, affected by uncertain factors such as the COVID-19, more and more foreign trade enterprises have a new understanding of the domestic and international markets. While playing a good "foreign trade card", they will make more effective overall use of both domestic and international markets and resources to promote more stable and powerful development of enterprises and more coordinated development of imports and exports. However, it should also be noted that domestic trade and foreign trade are economic activities carried out under the two standard systems at home and abroad, and there are differences in technology, quality and standards of enterprise products. At present, in the process of domestic and foreign trade integration, there are still problems such as the integrated regulation system needs to be improved, and the ability of enterprises to make overall use of two markets and two resources is still insufficient. To further promote the development of domestic and foreign trade integration and improve quality and efficiency, the government, society, enterprises and other aspects need to work together. The integration of domestic and foreign trade includes the integration of domestic and foreign trade in terms of business entities and management systems. We should improve laws and regulations, improve the regulatory system, and strengthen the docking of rules. Benchmark the international advanced level, promote the convergence of domestic and foreign trade regulatory rules, and promote the exchange of information, mutual recognition of supervision and mutual assistance in law enforcement between domestic and foreign trade regulatory authorities. We will optimize the business environment for domestic and foreign trade, improve the integrated regulatory system, and achieve efficient operation and mutual promotion of domestic and foreign trade. The enterprise is the implementation subject of the integrated development of domestic and foreign trade. Enterprises should be encouraged to innovate the integrated development model of domestic and foreign trade, make full use of modern information technology, speed up online and offline integration, promote the connection between production and marketing, supply and demand, actively cultivate new business forms and new models of domestic and foreign trade, and promote the integration of domestic and foreign trade industrial chains and supply chains. Firmly promote the comprehensive trial of cross-border e-commerce
