The value added of the country's manufacturing sector increased from 16.98 trillion yuan in 2012 to 31.4 trillion yuan in 2021. Wang Wei, head of the planning department of the Ministry of Industry and Information Technology, said that China's manufacturing industry has consolidated its scale advantage over the past decade, and its system integrity has become more prominent.

According to the statistical classification of national economy, China's manufacturing industry has 31 major categories, 179 middle categories and 609 subcategories. It is a global manufacturing industry with complete industrial categories and complete industrial system. The industrial chain has a global supporting capacity, with strong resilience and development potential. Such advantages of a complete system, complete supporting facilities, and strong organizational and collaboration capabilities have been fully demonstrated in the process of responding to external shocks such as the COVID-19 pandemic.

Product competitiveness has been significantly enhanced. In the past ten years, the export value of technology-intensive mechanical and electrical products and high-tech products has increased from 7.4 trillion yuan and 3.8 trillion yuan respectively in 2012 to 12.8 trillion yuan and 6.3 trillion yuan in 2021. The proportion of intermediate trade in manufacturing industry in the world has reached about 20%. The number of brands in industry and information technology listed in the World's top 500 brands has increased from 10 to 24.

"Over the past decade, the vitality and strength of Chinese market entities have increased." The number of Chinese market players continues to grow, with 400,000 industrial enterprises above designated size by the end of 2021, up 23.5 percent from 2012, Wang said. The operating revenue of China's top 500 manufacturing enterprises increased from 21.7 trillion yuan in 2012 to 40.24 trillion yuan in 2021. 58 manufacturing enterprises entered the World's Top 500 list in 2021, 27 more than in 2012. The professional capabilities of smes have been significantly improved. By the end of 2021, China had fostered more than 40,000 "specialized, specialized and innovative" smes, 4,700 specialized, specialized and innovative "little giant" enterprises, and more than 800 individual manufacturing enterprises.

Summary of materials used in pressure vessels

When two components A and B form an alloy, in addition to forming A or B based solid solution, it is possible to form A new phase whose crystal structure is different from that of A and B. Since their positions on the binary phase diagram are always in the middle, these are usually referred to as intermediate phases.
