The methods for classifying the size of enterprises are as follows:

1. According to the Circular of the Ministry of Industry and Information Technology (MIIT), National Bureau of Statistics (NBS), National Development and Reform Commission (NDRC), and the Ministry of Finance (MOF) on the Issuance of Provisions on the Standards for Classifying Small and Medium Enterprises (MIIT Lianshi Enterprise 〔2011〕 No. 300), and taking into account the actual situation of statistical work, these methods are hereby formulated. Small and medium-sized enterprises are divided into three types: medium-sized, small and micro, and the specific standards are formulated according to the indicators of employees, business revenue and total assets of the enterprises, combined with the characteristics of the industry.

2, this approach applies to the Chinese people *** and the territory of the State established by law in various organizational forms of legal person enterprises or units. Individual industrial and commercial households are divided with reference to this method.

3, the scope of application of these measures include: agriculture, forestry, animal husbandry and fisheries, mining, manufacturing, electricity, heat, gas and water production and supply, construction, wholesale and retail trade, transportation, storage and postal services, accommodation and catering, information transmission, software and information technology services, real estate, leasing and business services, scientific research and technological services, water conservancy, environment and public **** facilities management industry, residential services, repair and other services, culture, sports and entertainment industry and other 15 industry sectors, as well as social work industry broad categories.

4, enterprise division by the government's integrated statistics department based on the annual statistical report to determine once a year, the final report statistics in principle not be adjusted.

5, this approach since the date of issuance, the National Bureau of Statistics issued in 2003, "statistics on the division of large, medium and small enterprises (provisional)" (National Statistics [2003] No. 17) is repealed at the same time.

Enterprise size refers to the size of enterprises classified according to relevant standards and regulations. Enterprise scale is generally divided into extra-large, large, medium, small and micro. Enterprise size refers to the delineation of the scope of production, operation, etc. In May 2003, the National Bureau of Statistics formulated the "Measures for the Classification of Statistically Large, Medium and Small Enterprises (Provisional)" based on the Interim Provisions on the Standards for Small and Medium Enterprises jointly issued by four ministries and commissions, namely, the former State Economic and Trade Commission, the State Planning Commission, the Ministry of Finance and the National Bureau of Statistics, and the implementation of this Measure was begun with the 2003 Annual Report of the Statistical Year.

The "Measures for the Division of Statistically Large, Small and Medium-sized Enterprises (Provisional)" did not involve all the enterprises and units in the "National Economic Industry Classification" (GB/T4754-2002), and specified the delineation standards only for the following five categories:

The first category is the industrial sector, which includes the mining industry, the manufacturing industry, and the production and supply of electric power, gas, and water, and ** the three industry categories; the second category is the industrial sector, including the mining, manufacturing, and power, gas, and water production and supply sectors; and the second category is the small and medium-sized enterprises. ** three industry sectors; the second category is the construction industry; the third category is the wholesale and retail trade; the fourth category is the transportation and postal service industry (excluding warehousing); and the fifth category is the accommodation and catering industry. These five categories cover seven industry sectors and 673 industry sub-categories in the National Economic Industry Classification, accounting for about 74% of all industry sub-categories.

There are still 13 industry sectors in the ISIC that have not yet determined the standards for enterprise typing, mainly due to the following reasons: firstly, some industries lack basic statistical data, and cannot be effectively measured and analyzed without being typed for the time being; secondly, some special industries, such as the financial industry, whose products, modes of operation, and supervisory systems are quite different from those of the general industry, need to be studied and formulated separately; thirdly, the industry sectors that include "residential services" and "other services", including six other industry categories and warehousing industry, these industries will be in the country after the completion of the relevant census, and then according to the actual statistical situation to study and develop.
