At the closing of the Fifth Plenary Session of the 19th Central Committee of the Communist Party of China, more than 40 domestic leaders, well-known experts, scholars and business representatives from the circulation basin gathered at the Chinese Academy of Social Sciences to discuss the construction of a new “Dual Circulation” pattern for a modern circulation system. To build up a modern circulation system under the “14th Five-Year Plan”, it is necessary to clarify the basic requirements for the construction of a modern circulation system with “Three Definitions and One Focus”, and to explore the development trends and laws of the modern circulation system. To build up a modern circulation system, it is necessary to clarify the construction paths, methods, main contents and conditions for smooth progress, and to study and judge the integration, digitalization, intelligence, internal and external integration, unified planning and other trends in the development of modern circulation. Facing the problems of online and offline relationships in the modern circulation system, innovation in big data application, intelligent application, and idle business resources, scholars have put forward targeted countermeasures and suggestions.
