Introduction to standard data of A-share listed companies

 According to the definition of the "Standardization Law of the People's Republic of China", standards refer to technical requirements that need to be unified in the fields of agriculture, industry, service industries, and social undertakings.

Especially with the deepening of economic globalization, standards have become a basic element of a country's core competitiveness. Following product competition and brand competition, standards competition is becoming a deeper, higher-level, and more influential form of competition.

 Normally, the order when we select standards is: national standards → industry standards → group standards. When there are national standards and industry standards, priority will be given to national standards and industry standards. When there are no national standards and industry standards, the society can independently formulate group standards. However, when there are national standards and industry standards, the group standards formulated must be higher than the national standards and industry standards. Group standards with indicators lower than the national standards and industry standards are invalid standards.
