The industry is a set of enterprises characterized by the unity of the economic purpose of the products produced, the uniformity of the materials consumed, the common technical base and technological processes, a special professional staff, specific working conditions.


There is also such a concept as”industrial or national economic complex”. The following complexes function in the national economy: agricultural and industrial (AIC), military-industrial (MIC), machine-building, metallurgical, chemical and forestry, construction, fuel and energy (fuel and energy complex), etc.


An industrial complex is understood as a set of certain groups of industries that are characterized by the production of similar (related) products or the performance of works (services). For example, the fuel and energy complex includes the coal, shale, oil, gas industries, as well as the electric power industry. The main task of the fuel and energy complex is to provide the national economy, as well as everyday life with fuel and energy.


The sectoral structure of industry is understood as the composition of industries or complexes that are part of industry, and their share in the total volume of industrial production. The branch structure of the industry is constantly in motion. It is influenced by the following factors:


  • acceleration of scientific and technological progress. It is under the influence of this factor that new industries and production are formed. Thus, only in recent years, under the influence of the acceleration of the NTP, such industries as the feed industry, power engineering, space technology production, etc. have appeared.;


  • economic policy of the state. The state, implementing its chosen policy, can support individual industries that are most important in economic and social terms, and thereby influence the pace of their development;


  • availability of minerals suitable for industrial development in the country. The richer the country is in certain minerals, the higher, all other things being equal, the share of extractive industries in the total volume of industrial production;


  • the level of culture and material well-being of the people. This factor affects the industry structure in many ways. The ability to purchase consumer goods depends on the material standard of living of the people, which is the basis for the development of the industries that produce them. The presence of a middle class in the country contributes to the development of industries that produce durable goods: cars, refrigerators, video recorders, radio equipment, etc.
