What is the standard of industry division? What industries are divided into?

The so-called industry refers to the collection of manufacturers who produce or provide the same products or similar products or services.

There are many standards for industry classification. At present, the standards adopted by the National Bureau of Statistics should be the most authoritative national standards. The standard divides industries into 20 categories, namely:

A- agriculture, forestry, animal husbandry and fisheries; B- mining industry; C- manufacturing industry; D- production and supply of electricity, gas and water; Electronic construction industry; F- transportation, warehousing and postal services; G- information transmission, computer services and software industry; H- wholesale and retail; I- accommodation and catering industry; J- financial industry; K- real estate industry; L- leasing and commercial services; M- Scientific research, technical services and geological exploration; N- Management of water conservancy, environment and public facilities; O- residential services and other service industries; P- education; Q-health, social security and social welfare industries; R- culture, sports and entertainment; S- public management and social organizations; T- international organizations.

Under each big category, it can be divided into many small categories. In view of the space, I won't list them one by one.
