I want to know the specific differences between enterprises, industries and industries.

An enterprise is a profit-making economic organization engaged in economic activities such as production, circulation and service, which meets social needs with production or service, operates independently, accounts independently and is established according to law.

Industry generally refers to the categories of economic activities that are divided into producing similar products or having the same technological process or providing similar services, such as catering industry, clothing industry and machinery industry.

In the traditional socialist economic theory, industry mainly refers to the material production department of economy and society. Generally speaking, each department specializes in producing some independent products. In a sense, each department has become a relatively independent industrial department, such as "agriculture", "industry" and "transportation". Therefore, as an economic concept, the connotation and extension of "industry" are complicated.
