Unlock This CourseThe quaternary sector represents the most advanced part of our modern economy. Unlike primary industries that extract raw materials, secondary industries that manufacture goods, or tertiary industries that provide services, the quaternary sector focuses on knowledge, information and research. This sector has become increasingly important as countries develop and technology advances.
Key Definitions:
Quaternary sector jobs focus on thinking, creating and innovating rather than making physical products. Workers typically need university degrees and specialised training. The sector includes universities, research labs, software companies and financial services that create new knowledge and ideas.
The quaternary sector encompasses a wide range of knowledge-based activities. These jobs are characterised by their need for highly educated workers and their focus on creating, processing and sharing information.
Quaternary employment can be divided into several key areas, each playing a crucial role in the modern economy:
Scientists, researchers and engineers working in laboratories, universities and corporate R&D departments. They develop new medicines, technologies and solutions to global problems.
Software developers, data analysts, cybersecurity experts and IT consultants. They create apps, manage databases and protect digital information.
Investment bankers, financial analysts and insurance specialists who manage money, assess risks and provide complex financial products.
Universities are major quaternary employers. Cambridge University employs over 11,000 people in research and teaching roles. The university generates new knowledge through research, trains the next generation of quaternary workers and spins off high-tech companies that create thousands more jobs in the region.
Quaternary industries have specific needs that influence where they choose to locate. Unlike manufacturing industries that need raw materials or good transport links, quaternary industries prioritise access to skilled workers and knowledge networks.
Several factors make some locations more attractive than others for quaternary sector development:
Quaternary industries cluster near universities to access research facilities, skilled graduates and academic expertise. Silicon Valley's success is partly due to its proximity to Stanford University and UC Berkeley.
Highly skilled workers demand good housing, schools, cultural amenities and recreational facilities. Cities like Cambridge and Edinburgh attract quaternary industries partly because they offer an excellent quality of life.
Other Important Factors:
Established in 1970 near Cambridge University, this was one of the first science parks in the UK. Today it houses over 100 companies employing 7,000 people in biotechnology, software and electronics. Companies locate here to access Cambridge University's research, recruit top graduates and benefit from clustering with other high-tech firms. The park has helped transform Cambridge into one of Europe's leading technology centres.
The quaternary sector has experienced rapid growth in developed countries over the past 50 years. This growth reflects the transition from industrial to post-industrial economies and the increasing importance of knowledge and innovation.
Several factors explain why the quaternary sector has grown so rapidly:
The digital revolution has created entirely new industries and job types. Smartphones, social media and artificial intelligence have generated millions of quaternary jobs worldwide.
More people attend university than ever before, creating a larger pool of workers capable of quaternary employment. In the UK, over 40% of young adults now go to university.
Companies need sophisticated services to operate globally, creating demand for international banking, consulting and logistics services.
The UK has successfully developed a strong quaternary sector, particularly in London and university cities. This development has been supported by government policies, world-class universities and historical advantages in finance and research.
London is one of the world's leading financial centres, employing over 400,000 people in banking, insurance and related services. The City of London and Canary Wharf host headquarters of major banks and financial firms. London's success stems from its time zone (between Asia and America), English language, legal system and concentration of expertise. However, Brexit has created challenges as some firms relocate operations to EU cities.
The UK has developed several important quaternary sector clusters outside London:
Scotland: Edinburgh has become a major financial centre, while Glasgow and Aberdeen focus on energy research. The Scottish government actively promotes high-tech industries through grants and tax incentives.
Northern England: Manchester and Leeds have growing financial and digital sectors. The BBC's move to MediaCity UK in Salford has helped develop a creative industries cluster.
Cambridge-Oxford Corridor: This area between Cambridge and Oxford has the highest concentration of high-tech companies in Europe, earning the nickname "Britain's Silicon Valley."
The growth of the quaternary sector brings both opportunities and challenges for countries and regions.
High-value jobs: Quaternary workers typically earn above-average salaries
Innovation: Creates new technologies and solutions to global problems
Clean industry: Low environmental impact compared to manufacturing
Economic growth: Drives productivity and competitiveness
Skills gap: Shortage of qualified workers in some areas
Regional inequality: Benefits concentrated in certain areas
Job displacement: Automation may eliminate some traditional jobs
High costs: Expensive to establish and maintain R&D facilities
The quaternary sector is expected to continue growing as artificial intelligence, biotechnology and renewable energy create new opportunities. However, this growth will require continued investment in education, infrastructure and research to maintain competitiveness in the global knowledge economy.
Emerging technologies like quantum computing, gene therapy and space technology are creating new quaternary industries. The UK government has identified these as priority areas for investment, aiming to maintain the country's position as a global leader in the knowledge economy. Success will depend on attracting international talent, maintaining strong universities and creating supportive business environments.
