What areas does the national economy include?

China's National Bureau of Statistics clearly divides the national economy into three major industries:

Primary industry: agriculture;

Secondary industry: industry and construction;

Tertiary industry: other .

China introduced the classification standard GB/T4754-2002 for national economic industries, with 20 industry sectors, 95 major industry categories, 396 industry medium categories, and 913 industry subcategories.

According to the classification, transportation and commerce do not directly create material products, but they are responsible for transferring products from the place of production to the place of consumption and distributing goods to consumers.

It is a continuation of the production process, whereby material goods are circulated and distributed in such a way as to add value to transportation and commerce and increase the value of the original product. Thus, it is also included in the five major sectors of material production.

Other industries such as culture and education, health care, scientific research, public utilities, life services, tourism, etc. are categorized as non-material production sectors.

Expanded Information:

According to China's regulations, the indicators of national economic evaluation mainly include economic internal revenue and economic net present value or economic net present value rate. When the project is initially selected, static indicators such as the net benefit rate of investment can also be used.

1, economic internal rate of return (EIRR). Economic internal rate of return is a relative indicator to reflect the contribution to the national economy. It is the project in its calculation period when the cumulative economic net present value is equal to zero discount rate.

2. Economic net present value (ENPV) and economic net present value rate (ENPVR). Economic net present value is an absolute indicator of the project's contribution to the national economy. It is a social discount rate will be the project calculation period of the net benefit of each year discounted to the construction of the starting point (construction of the initial period) of the present value of the sum.

When the economic net present value is greater than zero, it means that after the country pays for the proposed project, in addition to compensation in line with the social discount rate, but also to get the excess social surplus calculated in present value. Economic net present value rate is to reflect the project unit investment for the national economy to make a net contribution to the relative indicators, it is the economic net present value and the present value of the investment ratio.

Economic net present value of the project is greater than or equal to zero, the national economic evaluation should be considered acceptable. In selecting the program, should choose the program with a large economic net present value; when the investment amount of each program is different, it is necessary to use the economic net present value rate to measure.

3, the net benefit rate of investment. Investment net benefit rate refers to the project to reach the design capacity of a normal production year, its annual net benefit and the ratio of total investment in the project. It is an indicator that reflects the net contribution of the unit investment to the national economy after the commissioning of the project. In the production period of the net benefit of the project in each year of large changes in the production period should be calculated as the average annual net benefit of the production period and the ratio of total investment.
