Industrial classification involves categorizing companies based on their primary business activities, particularly focusing on companies that produce and distribute goods and services. This classification excludes utilities, transportation companies, and financial service companies, and is primarily used in the context of stock markets and economic analysis.
Definition and Types of Industrial Classification
Industrial classification refers to the systematic categorization of companies into groups that produce and distribute tangible goods and services. This classification helps in economic analysis, stock market segmentation, and understanding industrial contributions to the overall economy.
Standard Industrial Classification (SIC)
The Standard Industrial Classification (SIC) system categorizes industries based on a four-digit code. Each industry’s primary activity is indicated by a specific SIC code, which ranges from manufacturing to service provision sectors.
North American Industry Classification System (NAICS)
The NAICS, jointly developed by the United States, Canada, and Mexico, uses a more modern six-digit code system that reflects changes in the economy due to technological advancements and globalization.
Special Considerations

- Transportation: Companies involved in the movement of goods and individuals, including airlines, shipping, and logistics firms.
- Financial Services: Institutions providing financial products and services, including banks, insurance companies, and asset management firms.
Historical Context

Industrial classification is crucial in various domains:
- Economic Analysis: Economists use industry classifications to assess sectoral contributions to GDP, productivity, and employment.
- Stock Market Analysis: Investors and analysts classify companies to create sector-specific investment strategies and indices.
