In the process of transformation and upgrading of China's manufacturing industry, the pace of continued expansion of large enterprises will not stop, and the innovative role of small and medium-sized enterprises will become active at a faster pace in the global division of labor system and develop rapidly.

At present, China is the country in the world with all the industrial categories (39 major categories, 191 medium categories and 525 small categories) in the United Nations industrial classification, and has a complete industrial chain. And with the gradual formation of industry oligarchs, more small enterprises will be multiplied in the industrial chain and supply chain. The competitiveness of enterprises is cultivated through continuous management improvement and innovation in the competition, which requires a hard struggle process. Whose service is better, whose management is better, whose quality is better, will stand out in this round of development.
