What industries do traditional industries refer to?

Traditional industry is a historical relative concept, and there is no standard definition of traditional industry. This paper introduces some scholars' understanding of it in order to grasp its main connotation, and does not expect to give a strict definition and explanation.

Wang Jiaqiong of Northern Jiaotong University believes that traditional industries are relative to emerging industries such as information industry and new materials industry, mainly including steel, coal, electricity, construction, automobile, textile, light industry, shipbuilding and other industries.

According to Dosi technical specification theory, Taibing divides technical activities into traditional technology and high technology, and calls the industries supported by corresponding technologies corresponding industries. Therefore, industries can be divided into traditional industries and high-tech industries. The industry formed by using traditional technical specifications to solve various production problems is called traditional industry; The application of new technical specifications, that is, high-tech to solve problems in production, which traditional technology can not solve, is called high-tech industry.

Liu Shijin and others believe that traditional industries are industries that produce and serve with traditional technologies, and refer to industries that play a pillar and foundation role in the process of industrialization. Mainly industry, but also some traditional agriculture and tertiary industry. The pillar industries in the era of industrial economy are textile, steel, electromechanical, automobile, chemical industry, construction and other material production industries.
