Quaternary economic sectors refer to the segment of the economy focused on knowledge-based activities involving services such as research and development, financial planning, education, and information technology. This sector emphasizes the importance of intellectual capabilities and innovation, making it a critical component in a rapidly changing global economy. It is increasingly significant as economies evolve from manufacturing and primary production toward service-oriented industries.
The quaternary sector influences urban growth, creates specialized job markets, and drives global economic shifts towards knowledge-based services. It often leads to the clustering of skilled workers and can contribute to regional disparities in wealth and development.
