Industrial district concept was initially used by Alfred Marshall to describe some aspects of the industrial organisation of nations. Industrial district (ID) is a place where workers and firms, specialised in a main industry and auxiliary industries, live and work. At the end of the 1990s the industrial districts in developed or developing countries had gained a recognised attention in international debates on industrialisation and policies of regional development. History of the term The term was used the first time by Alfred Marshall in The Principles of Economics (1890, 1922). and in "Industry and Trade". Marshall talks of a.... "thickly peopled industrial district". The term was also used in political struggle. The 1917 handbook of the Industrial Workers of the World states:- "In order that every given industrial district shall have complete industrial solidarity among the workers in all industries as well as among the workers of each an INDUSTRIAL DISTRICT COUNCIL is formed ..."

In a thorough industrial district, it is not easy for the girls who have expectations above the common to find husbands. The ugly industrial town was full of men, young men who were ready to marry. But they were all colliers or pottery-hands, mere workmen."

Competences and knowledge are shared in informal way with processes of learning by doing and learning by using, and this promotes innovation over time. Local firms, families and civic organisations are connected by way of both market mechanisms and non-market mechanisms, like trust within bilateral or team exchanges, and collective action supporting the availability of local industrial, social and environmental infrastructure. Also, the notion that firms located in geographical proximity benefit from agglomeration effects in having a common or collective infrastructure is frequently mentioned as one of the main bases in the industrial district literature. Recent evolution of the use of the term Within the study of economics, the term has evolved. Giacomo Becattini rediscovered the concept to describe the Italian industrial configuration of the middle of the 20th century. Since the 1980s, the dynamic industrial development in NEC (North,
