===Learning and growth economies===
[[Learning-by-doing (economics)|Learning]] and [[Economic growth|growth economies]] are at the base of dynamic economies of scale, associated with the process of growth of the scale dimension and not to the dimension of scale per se. Learning by doing implies improvements in the ability to perform and promotes the introduction of incremental innovations with a progressive lowering of average costs.{{sfnmp|1a1=Rosenberg|1y=1982 |2a1=Levin|2a2=Klevorick|2a3=Nelson|2a4=Winter|2y=1987 |3a1=Scherer|3y=2000|3p=22}} Learning economies are directly proportional to the cumulative production ([[Experience curve effects|experience curve]]).
Growth economies emerge if a company gains an added benefit by expanding its size. These economies are due to the presence of some resource or competence that is not fully utilized, or to the existence of specific market positions that create a differential advantage in expanding the size of the firms. That growth economies disappear once the scale size expansion process is completed. For example, a company that owns a supermarket chain benefits from an economy of growth if, opening a new supermarket, it gets an increase in the price of the land it owns around the new supermarket. The sale of these lands to economic operators, who wish to open shops near the supermarket, allows the company in question to make a profit, making a profit on the revaluation of the value of building land.{{sfnmp|Penrose|1959|1pp=99-101|Morroni|2006|2p=172}}
