What is the development of industries for machine production of goods called?

The development of industries for machine production of goods is best described as industrialization. This term specifically refers to the process where economies transition from manual production methods to mechanized manufacturing, greatly enhancing efficiency and output. Industrialization entails the establishment of factories, the use of steam and later electrical power, and the mass production of goods, fundamentally altering social structures, economic systems, and ways of life.

While industrial expansion and technological advancement are related concepts—focusing on growth within existing industries and innovations, respectively—they do not capture the broader shift in production processes that defines industrialization. Similarly, the term Industrial Revolution refers to a specific historical period during which industrialization took place, characterizing substantial economic and technological change in the late 18th and 19th centuries. However, it does not encompass the ongoing process of industrialization that continues in various forms today. Therefore, the most accurate term for the development of industries centered around machine production is indeed industrialization.
