I. Relevant Applications
The International Standard Industrial Classification (ISIC) promulgated by the United Nations is characterized by the fact that it maintains a stable connection, thus facilitating the hierarchical in-depth study of industrial structure. The ISIC of the United Nations is easy to be adjusted and revised, and it also provides very convenient conditions for countries to formulate their own standard industrial classifications and conduct comparative studies on the industrial structure of various countries.
For example, China's national standard "Classification and Coding of National Economic Industries" (GB/T 4754-2011) adopts the classification standard of the fourth revised edition of the International Standard Industrial Classification (1SIC) in 2008. Western countries mostly formulate standard industrial classifications for official use according to the UN ISIC.
Second, the advantages
The advantages of the Standard Industrial Classification are that it classifies and standardizes all economic activities, is highly comparable, is conducive to the analysis of the industrial structure of various countries and regions, and is closely linked to the three industrial classifications.
