In order to meet the needs of different purposes in industrial analysis in various fields of industrial economics, industries can be divided into several levels, which is the stage of "industrial collection". Specifically, there are three levels of industries in industrial economics:

(1) The first level is the industry divided by the same commodity market, that is, the industrial organization. In reality, the relationship structure of enterprises in different industries is different.

The enterprise relationship structure in an industry has an extremely important impact on the economic benefits of the industry. In order to achieve the best economic benefits, an industry must meet two conditions: first, the nature of the enterprise relationship structure in the industry makes the enterprises in the industry have enough pressure to improve their operations, improve their technology and reduce their costs; Secondly, make full use of "economies of scale" to make the unit cost of enterprises the lowest.

(2) The second layer is the industry that is divided based on the similarity of technology and technology, that is, industrial association. In the process of social reproduction in a certain period of a country, various industrial departments have input and output through certain economic and technological relations, that is, the movement of intermediate products, which truly reflects the proportional relationship and changing law in the process of social reproduction.

(3) The third level is roughly based on the stage of economic activities, which divides the national economy into several industries, that is, industrial structure.
