In order to facilitate the collection and comparison of national statistical data, the United Nations Bureau of Economic and Social Affairs has formulated the International Standard Industrial Classification for all economic activities, which is recommended to be adopted by all countries. It divides the national economy into 10 categories, and then divides each category into large categories, medium categories and small categories.

First, related applications

The International Standard Industrial Classification (ISIC) promulgated by the United Nations is characterized by maintaining a stable relationship with the three major industrial classifications, which is conducive to the hierarchical and in-depth study of industrial structure. The United Nations Standard Industrial Classification is easy to adjust and revise, and it also provides a very convenient condition for countries to formulate their own standard industrial classification and make a comparative study of industrial structures in various countries.

For example, the national standard National Economic Industry Classification and Code (GB/T 4754-20 1 1) formulated by China adopts the classification standard of the International Standard Industrial Classification (1SIC) revised for the fourth time in 2008. Western countries often make official standard industrial classification according to the United Nations International Standard Industrial Classification.

Second, advantages

The advantage of standard industrial classification is that it classifies all economic activities, makes them standardized, has strong comparability, is conducive to analyzing the industrial structure of various countries, and is closely related to the three major industrial classifications.
