Accelerating the construction of a unified national market is an inevitable requirement to smooth the domestic circulation and promote the construction of a new development pattern. It is also an important lever to unleash the potential of domestic demand and consolidate the foundation for economic recovery. Currently, how can we better focus on building a unified national market? Xinhua News Agency reporters went to Jiangxi, Zhejiang, Jiangsu, Guizhou and other places to conduct research and gain in-depth understanding of various measures taken by various regions to promote the construction of a unified national market. Connecting "Breakpoints" and Revitalizing the Large Market In April, the sky was just dawn, located in Nanchang County, Nanchang City, Jiangxi Province, at the Nanchang Xiangtang International Land Port. The whistle sounded, and the train slowly started with the dawn. This train is loaded with hundreds of vehicles produced by Jiangling Group, and its destination is Nansha Port in Guangzhou. It has completed a series of customs clearance processes such as declaration, inspection, and release at Nanchang Land Port. After arriving at Nansha Port, there is no need for further inspection and it can be "set sail". "Coastal ports such as Guangzhou Port have a large volume of goods, and container clearance often takes a long time. The entire process can now be completed in advance at Nanchang Land Port, which is equivalent to two ports being one port, helping enterprises save time and costs." said Leng Zhiqiang, director of Nanchang County Port Economic Development Promotion Center. Leng Zhiqiang told reporters that in recent years, through the continuous promotion of integrated customs clearance policies and the construction of a fast and smooth logistics system, Nanchang County, which is not coastal, has had an "outlet". In the future, more "made in Jiangxi" will be continuously sent to the national and global markets. The exploration of integrated customs clearance in Nanchang County is a vivid reflection of the construction of a unified national market. The key to building a unified national market is "unity", which emphasizes the connection between various factors in the market. This requires breaking down market segmentation and connecting regional "breakpoints", and promoting the orderly flow of various resource elements such as technology, funds, and talent. At present, some local market rules and market information are not well connected, or other conditions are attached to market access, and some cannot strictly implement fair market supervision without discrimination... "Building a unified national market, in simple terms, is the" five unifications "and" one elimination ", which means building an efficient, standardized, fair competition, and fully open super large scale market through unified basic institutional rules, unified connected market facilities, unified factor resource markets, unified commodity and service markets, unified market supervision, and the elimination of local protection." The head of the National Development and Reform Commission said. As a major province in the digital economy, Zhejiang has taken the lead in promoting the construction of a unified national market. During the investigation, the reporter learned that by fully utilizing technological advantages and breaking the temporal and spatial boundaries of government services, Zhejiang has been approved as the first national pilot project for integrated application of electronic business licenses. At the same time, it has led the construction of "enterprise codes", achieving deep application in 39 fields, and the download volume of electronic business licenses exceeds 9.02 million. "At present, the full process online processing rate of enterprises in the province has reached 96.8%, basically achieving 'one link, one day processing, and zero cost'." The head of the registration and registration office of the Zhejiang Provincial Administration for Market Regulation said that Zhejiang has introduced business norms and technical standards for digital construction of enterprise registration archives, fully connected the archive query systems of various registration agencies in the province, integrated and streamlined the migration process, and achieved online processing of the entire process of "one thing" migration within the province.
