In the 1920s, the International Labour Office made a systematic division of industries, that is, all industries in a country were divided into primary production departments, secondary production departments and service departments. Later, many countries referred to the classification method of the International Labour Office when dividing industries. After World War II, most western countries adopted three industrial classifications. In China, industries are divided as follows: the primary industry is agriculture, including agriculture, forestry, animal husbandry and fishery; The secondary industry is industry, including mining, manufacturing, tap water, electricity, steam, hot water, gas and construction; The tertiary industry is divided into two parts: communication and service, with four levels: ① circulation department, including transportation, post and telecommunications, commerce, catering, material supply and marketing and warehousing. ② Departments serving production and life, including finance, insurance, geological survey, real estate, public utilities, residents' service, tourism, consulting information service and various technical services. (3) Departments that serve to improve the scientific and cultural level and quality of residents, including education, culture, radio, television, scientific research, health, sports and social welfare. (four) departments that need to serve the public, including state organs, political party organs, social organizations, the army and the police.
The so-called industry is an enterprise group whose members are in close contact with each other to a great extent because of the substitutability of its products (both tangible and intangible), and are different from other enterprise groups because of the differences in product substitutability.
In the national economy, the growth of some industries keeps pace with the growth of GNP, some industries grow faster than GNP, and some industries grow slower than GNP. In view of this phenomenon, if you choose an enterprise to invest, you should study the industry in which it is located, that is to say, study the nature of the industry, especially the growth trend. Understanding the growth of the industry is helpful to formulate the correct investment strategy.
1, the difference in meaning:
1. 1. Industry refers to the title that all kinds of industries play different roles in the distribution of social productive forces, mainly referring to the economic and social material production departments, and it is a meso-economy between macro-economy and micro-economy.
1.2. Industry refers to various economic activities characterized by the combination of production factors, and refers to the categories of economic activities classified by producing similar products or having the same technological process or providing similar services.
2. Level difference:
2. 1. From the level, industries and industries are from high to low in focus, and the conceptual scope is from large to small. Simply put, industry >; Industry;
2.2. Industry reflects productivity and belongs to the macro-economic category;
2.3, the industry reflects the factors of production, belonging to the category of microeconomics;
2.4 Generally speaking, by industry, we divide the national economy into primary industry (agriculture), secondary industry (industry) and tertiary industry (circulation and service industry);
2.5. The national economy is divided into catering industry, clothing industry, machinery manufacturing industry, IT industry and financial industry.
To sum up, the industry focuses on productivity, which belongs to macroeconomics and has a wider scope; The industry focuses on production factors, which belongs to microeconomics and has a smaller scope.

What is the difference between engineering density and density? Density refers to the ratio of the volume occupied by atoms to the volume occupied by cells.
Generally, the atom is regarded as a rigid sphere, and then the relationship between the number of atoms in a unit cell, the atomic radius and the lattice constant can be calculated, and the density k can be calculated.
For example, the body-centered cube: the number of atoms is 2, the atomic radius is (radical number 2)/4*a, and the unit cell volume is a^3；; ; The calculated density K=0.68.
Density is a physical quantity that reflects the characteristics of matter, and the characteristics of matter refer to a property that can be distinguished from each other. People often think that substances with high density are "heavy" and substances with low density are "light". The "heavy" and "light" here essentially refer to the size of density.
Mass is the quantity of matter contained in an object. The substance content decreases, so the mass decreases. Density is a characteristic of a substance, which does not change with the change of mass and volume, and the density of the same substance remains unchanged.
Density is a characteristic of matter, which is only related to the type of matter, and has nothing to do with factors such as mass and volume. Different substances generally have different densities, while the density of the same substance is the same.
The formula of density: ρ = m/v (ρ means density, m means mass and v means volume).
What's the difference between EMPORION ARMANI and GIORGIO ARMANI? What is the difference? Armani, which is usually said, is not accurate.
