What is a Key Industry?
A Key Industry is an industry sector that plays a strategically important role in a country’s or region’s economy due to its contribution to employment, GDP, exports, innovation, or national security. Governments and investors often prioritise key industries for policy support and long-term development.
Definition

Key Takeaways

Understanding Key Industries
What qualifies as a key industry depends on national priorities, resource endowments, and economic structure. In developing economies, key industries may include agriculture, mining, or energy. In advanced economies, technology, finance, healthcare, and advanced manufacturing often dominate.
Governments may designate key industries to:
- Protect employment
- Strengthen economic resilience
- Promote innovation and competitiveness
- Safeguard strategic or security interests
Policy tools supporting key industries include subsidies, tax incentives, trade protections, infrastructure investment, and skills development programs.
Formula (If Applicable)
There is no single formula, but key industries are commonly identified using indicators such as:
- Contribution to GDP
- Employment share
- Export value
- Productivity and value-added
- Strategic or security relevance
