Dinamiche di settore e cambiamento strategico

[Autom. eng. transl.] The dynamics of the sector are the changes that lead to the birth, structural change and extinction of the sector. The sector: - was born as a result of an innovation in the satisfaction of customer needs, by subjects who see a source of profit in this innovation, where by profit we do not mean a simple positive difference between revenues and costs, but a return higher than cost of the capital; - it changes in a structural way when the structural conditions of the sector are altered by the initiative of those who work inside or outside the sector; - it is extinguished when the subjects that make up the sector recognize that the conditions for obtaining a profit by satisfying customer needs have failed and, sometimes with delays due to the presence of "exit barriers", abandon it.
