David's Time With Peter F. Drucker 2020.4.7 What do these developments in the 20th century's growth sectors mean for the 21st century's strategy of an industry and of a particular institution within it, whether a business, a university, a hospital, a church? The answer to this question first requires defining what makes an industry a “growth” industry, a “mature” industry or a “declining” industry. A growth industry is one in which the demand for its products, whether goods or services, grows faster than naitional income and/or population. An industry in which the demand for its products or services grows as fast as national income and/or population is a “mature” industry. And an industry in which the demand for its products or services grows less fast than naitonal income and/or population is a “declining” industry, even if its absolute sales volume still continues to grow. ——《Management Challenges for the 21st Century · Chapter2》(Peter F.Drucker,1999)
