Sichuan and Chongqing are geographically close and trade frequently. Maoge Food Development Co., Ltd., located in Yubei, Chongqing, sells its products well across both Sichuan and Chongqing, with annual output value exceeding 90 million yuan last year. "Sichuan is the most important sales region for our products," said Zhou Houjuan, a relevant person in charge of the company, noting that last year the company put two fine-processing plants into operation in Sichuan, with sales exceeding 50 million yuan.

　　Data shows that in the first half of this year, trade between Sichuan and Chongqing reached 431 billion yuan, up 7.8% year on year. Among this, sales revenue from wholesale and retail and from manufacturing between the two places grew 9.8% and 3.2% year on year respectively, while procurement amounts grew 11.6% and 3.5% year on year respectively.

　　The Decision of the Central Committee of the Communist Party of China on Further Comprehensively Deepening Reform and Advancing Chinese Modernization (hereinafter referred to as the Decision), adopted at the Third Plenary Session of the 20th Central Committee of the Communist Party of China, further deployed reform measures to build a unified national market. Promoting the efficient and free flow of domestic goods and services is one of the main goals of building a unified national market, and the invoice-based purchase and sales relationships can reflect the closeness of trade ties between provinces across the country.

　　Value-added tax invoice data recently released by the State Taxation Administration shows that from January to July this year, nationwide inter-provincial sales grew 3.8% year on year; inter-provincial trade sales accounted for 40.6% of total sales, 0.6 percentage points higher than the same period last year. Of the country's 31 provinces, 22 achieved positive growth in inter-provincial trade sales, with 13 of them growing faster than the national average.

　　Taking the Sichuan-Chongqing region as an example, the building of a unified national market is accelerating the coordinated development of industrial chains in the two places. "Since the beginning of this year, we have sold more than 1.18 million camshafts to Chongqing, generating an output value of nearly 60 million yuan," said He Qin, head of finance at Sichuan Yinguang Yitong Camshaft Co., Ltd.

　　It is understood that the Hechuan-Wusheng jointly built industrial park where the company is located is an industrial park jointly built by Wusheng County of Sichuan Province and Hechuan District of Chongqing Municipality. In recent years, enterprises in the park have actively integrated into the Chengdu-Chongqing economic circle and accelerated the expansion of the national market. The tax authorities of Hechuan and Changshou in Chongqing and Guang'an in Sichuan jointly issued the Work Plan for Tax Services to Support the Construction of the He-Guang-Chang Coordinated Development Demonstration Zone, actively serving enterprises' cross-provincial development.

　　The building of a unified national market is conducive to making the domestic economic circulation smoother and has brought relatively rapid growth in inter-provincial trade. The three major growth engines of Beijing-Tianjin-Hebei, the Yangtze River Delta and the Pearl River Delta have strengthened their radiating and driving role for areas outside their regions.

　　Value-added tax invoice data shows that from January to July this year, out-of-region sales of Beijing-Tianjin-Hebei, the Yangtze River Delta, the Pearl River Delta and the Chengdu-Chongqing region grew 2.8%, 4.3%, 5.3% and 6.6% year on year respectively, all higher than the overall growth rate of the four major regions.

　　Trade between key regions is also very frequent. Value-added tax invoice data shows that from January to July this year, sales from Beijing-Tianjin-Hebei to the Pearl River Delta and the Chengdu-Chongqing region grew 6.4% and 4.2% year on year respectively; sales from the Yangtze River Delta to the Pearl River Delta and the Chengdu-Chongqing region grew 7.2% and 8.7% year on year respectively; sales from the Pearl River Delta to Beijing-Tianjin-Hebei and the Chengdu-Chongqing region grew 8.9% and 10.3% year on year respectively; and sales from Chengdu-Chongqing to the Yangtze River Delta and the Pearl River Delta grew 8.2% and 14.2% year on year respectively.

　　Laoting County in Tangshan City, Hebei Province, is located in the heart of the Bohai Rim economic circle and is rich in steel resources. In recent years, it has seized the opportunity of Beijing-Tianjin-Hebei coordinated development and actively taken over the transfer of the Beijing-Tianjin building support equipment manufacturing industry, becoming an important production base for formwork and scaffolding in China.

　　In recent years, with the in-depth advancement of the unified national market strategy, North China Yi'ande Scaffolding Manufacturing Co., Ltd., which has settled in the economic development zone of Laoting County, Tangshan, has seen unprecedented development momentum. "We are involved in major engineering projects in Beijing, Tianjin and other places," said Xu Xiaoyue, head of finance at the company.

　　The Decision points out that it is necessary to cultivate a nationally integrated technology and data market. In recent years, computing infrastructure has attracted much attention. The implementation of the "East Data, West Computing" project has driven the development of industrial chains such as IT equipment manufacturing, information and communications, and basic software, and is an important measure to promote coordinated linkage between the east and west and serve the building of a unified national market.

　　Value-added tax invoice data shows that from January to July this year, nationwide inter-provincial sales of science and technology services grew 18% year on year, 1.5 percentage points higher than the overall sales growth of science and technology services. Nationwide inter-provincial sales of information services grew 14.8% year on year, 1.1 percentage points higher than the overall sales growth of information services.

　　The reporter learned that, in order to better serve the building of a unified national market, the State Taxation Administration recently issued the Notice on Further Facilitating Cross-Region Relocation of Taxpayers and Serving the Building of a Unified National Market, to further facilitate cross-region relocation of taxpayers and continuously optimize the tax business environment.

　　Shen Xinguo, director of the Taxpayer Service Department of the State Taxation Administration, said that next, the tax authorities will, through the effective exercise of their tax functions, better serve the building of a unified national market, smooth the domestic circulation and promote high-quality development.
