An industry is a specific branch of the economy that groups companies together based on their primary business activities, products, or services. At its core, an industry utilizes raw materials, labor, and capital to produce economic goods or deliver services to satisfy consumer demands.
Economies break down industries into four distinct sectors to track how raw goods evolve into high-tech innovations. 1. Primary Industry (Extraction)
Definition: Involves harvesting or extracting natural, raw resources directly from the earth or sea.
Examples: Agriculture, mining, forestry, oil extraction, and fishing.
Economic Role: Forms the foundational base of all supply chains; tends to dominate developing economies. 2. Secondary Industry (Manufacturing)
Definition: Takes raw materials from the primary sector and transforms them into tangible, finished consumer or producer goods.
Examples: Automotive manufacturing, textile mills, food processing, and construction.
Economic Role: Often divided into heavy industry (requiring massive capital and machinery) and light industry (smaller-scale, consumer-focused goods). 3. Tertiary Industry (Services)
