What is the Quaternary Industry?
The Quaternary Industry refers to activities centred on the generation, interpretation and dissemination of knowledge. It is often described as a knowledge‑intensive part of the economy that focuses on high‑skill, high‑value services rather than physical outputs. In practical terms, the Quaternary Industry includes research and development (R&D), information services, education, culture, digital content, consultancy, analytics and policy advisory work. It is characterised by high levels of specialisation, intellectual property creation and a strong reliance on information technology and communications infrastructure.
Origins and Definition
The concept evolved from observations that economies increasingly rely on ideas and intellectual capital as much as on natural resources or manufactured goods. Within the Quaternary Industry, value is created through innovative thinking, rigorous evaluation and the dissemination of knowledge.
