The classification of industries is a crucial aspect of economic analysis, business strategy, and policy-making. Industries are diverse and encompass a wide range of economic activities. Understanding how industries are categorized can provide insights into market dynamics, consumer behavior, and the overall economic landscape. This article delves into various methods of classifying industries, aiming to provide a comprehensive overview of the subject.
1、Departmental Classification
The departmental classification method is one of the oldest and most straightforward ways to categorize industries. It involves dividing the economy into major sectors based on the type of economic activity. This method is often used in national accounts and macroeconomic analysis.
Primary Sector: This sector includes activities that extract natural resources from the earth. It includes agriculture, forestry, fishing, mining, and quarrying.
Secondary Sector: The secondary sector involves the processing and manufacturing of raw materials obtained from the primary sector. This includes industries such as manufacturing, construction, and utilities.

Tertiary Sector: Also known as the service sector, this category encompasses activities that do not produce tangible goods but provide services. This includes retail, healthcare, education, finance, and transportation.
2、Standard Industrial Classification (SIC)
The Standard Industrial Classification (SIC) system is a widely used classification scheme that categorizes businesses into 20 major categories based on the nature of their economic activities. The SIC was established in the United States but has been adopted globally.
Division: The highest level of classification, which consists of broad categories such as agriculture, manufacturing, and wholesale trade.
Major Group: Subdivisions of divisions, representing more specific industry groups, such as food manufacturing or automobile manufacturing.
Minor Group: Further subdivisions within major groups, which are more detailed and reflect specific industries, like meat packing or motor vehicle manufacturing.
Industry: The most detailed level, which represents specific businesses within the industry, such as meat packing plants or automobile assembly plants.
3、North American Industry Classification System (NAICS)
The North American Industry Classification System (NAICS) is the successor to the SIC system and is used in the United States, Canada, and Mexico. It provides a more detailed and flexible classification scheme that reflects the evolving nature of the economy.
Sector: The highest level of classification, similar to divisions in the SIC system, but more detailed, such as agriculture, mining, and utilities.

Subsector: Subdivisions of sectors, which are more specific, like crop production or oil and gas extraction.
Industry: The most detailed level, which reflects specific businesses, such as wheat farming or crude petroleum and natural gas extraction.
4、Global Industry Classification Standard (GICS)
The Global Industry Classification Standard (GICS) is a widely accepted classification system used in the financial industry, particularly for the categorization of stocks. It is managed by the MSCI Barra and FTSE Russell.
Sector: The broadest category, such as consumer discretionary, health care, or technology.
Industry Group: A more specific category within a sector, like automotive or biotechnology.
Sub-industry: A further subdivision within an industry group, such as luxury autos or biopharmaceuticals.
Constituent: The most detailed level, representing individual companies that are part of a sub-industry.
5、Value Chain Classification
This method categorizes industries based on the value chain, which is the sequence of activities that add value to a product or service from raw materials to the final product.

Primary Activities: These are the core activities that create the product or service, such as production, marketing, and sales.
Support Activities: These are auxiliary activities that support the primary activities, such as research and development, procurement, and logistics.
6、Market-Based Classification
This classification method categorizes industries based on the market in which they operate, considering factors such as consumer demand, competition, and technological trends.
Consumer Goods: Industries that produce goods for direct consumption by end-users, such as food and beverage, personal care, and apparel.
Business Goods: Industries that provide goods and services to other businesses, such as industrial machinery, software, and consulting services.
In conclusion, the classification of industries can be approached through various methods, each offering different perspectives and levels of detail. The choice of classification method depends on the specific context and the purpose of the analysis. Whether for economic policy, business strategy, or financial investment, understanding how industries are categorized can provide a solid foundation for decision-making.
