Quick Reference

A sector of the economy in which firms use similar factor inputs to create a group of related products and/or services. The extraction of natural resources, including agriculture, is primary industry; manufacturing is secondary industry; tertiary industry comprises services, including transportation and communication; quaternary industry deals with a range of producer services from banking to retailing to real estate; and quinary industry with consumer services such as education, health care, and government information. With economic development, industry moves from primary industry to progressively less material-oriented activities such as textiles and clothing, until, over time, tertiary industries dominate; the sequence is illustrated in the figure.

The relative dominance of the latter three categories over the former two in many industrialized countries has informed discussions of a post-industrial society, in which Miozzo and Soete (2001) Tech. Forecast. & Soc. 67, 2 identify research and development, design, marketing, distribution, and after-sales maintenance as essential.

Phelps and Ozawa (2003) PHG27, 5 propose four industrial phases.
