Economics – Microeconomic decision-makers - Firms | e-Consult

Primary sector firms are those directly involved in extracting raw materials from the earth. Examples include agriculture, fishing, forestry, and mining. Their activities are often weather-dependent and require large areas of land. Capital intensity is generally low, relying more on labour and natural resources. Employment tends to be seasonal and often associated with lower skill levels.

Secondary sector firms transform raw materials into finished goods. This includes manufacturing industries like car production, food processing, and textiles. These firms typically have high capital intensity, requiring significant investment in machinery and factories. Employment is often more skilled than in the primary sector, but can be vulnerable to automation.

Tertiary sector firms provide services to consumers and businesses. Examples include retail, banking, healthcare, education, and tourism. Capital intensity can vary, but many tertiary sector firms rely heavily on human capital and knowledge. Employment is generally high-skilled and often provides better wages and working conditions than the primary and secondary sectors. The tertiary sector is often the largest sector in developed economies.
