The total output of agriculture, forestry, animal husbandry and fishery is calculated by the product method, that is, all agricultural products with product output are calculated by multiplying the unit product price by the output.

the total industrial output is calculated by the "factory method". The so-called "factory method" is to take the industrial enterprise as a whole and calculate the total output according to the final results of the industrial production activities of the enterprise, and the value of products within the same enterprise is not allowed to be calculated twice.

the total output of the construction industry is calculated by two methods: one is to calculate directly from the perspective of construction production activities of construction enterprises and self-operated construction units; The other is from the perspective of the construction cost of the owner of the construction products. Considering the stability of building products and the liquidity characteristics of construction units, the latter method is the main method at present.

the total output of transportation, warehousing and postal services is equal to its operating income.

the total output of wholesale and retail industry is equal to the commercial surcharge, that is, the net sales income of goods minus the cost of goods sales.

the total output of accommodation and catering industry is equal to its operating income.

the total output of the banking industry is equal to the virtual service income of financial media service activities plus the actual service fee income. Among them, the virtual service income is equal to the difference between interest income and interest expenses, but the interest income obtained by the banking industry using its own funds should be deducted. The actual service fee income is fee income and other business income. The formula of total output of the banking industry is:

total output of the banking industry = virtual service fee income+actual service fee income

= various interest income-various interest expenses+handling fee income+trust business income+financial leasing business income+foreign exchange business income+investment dividend income

The calculation method of total output of the insurance industry is similar to that of the banking industry, which is equal to the difference between premium income and claim payment plus other operating income. The specific formula is:

total output of insurance service = operating income-indemnity expenditure-surrender premium and payment-reinsurance premium expenditure-reinsurance indemnity and expense expenditure-deposit of outstanding indemnity reserve-reserve accrual+investment income

, in which operating income includes premium income and other operating income.

the total output of the real estate industry includes the total output of the real estate development and management industry, the total output of property management, the total output of real estate intermediary services and the total output of residents' own housing services. The total output of real estate development and management industry is the difference income from housing sales and the rental income from real estate leasing activities; The total output of property management is the operating income of management services; The total output of real estate intermediary service is the income obtained from engaging in real estate brokerage and agency intermediary activities. In principle, the total output of residents' own housing services should be equal to the virtual rent calculated according to the rent price of the same housing in the market. Because China has not yet formed a sound real estate market, there is no suitable rent price to refer to. At present, the virtual depreciation of fixed assets calculated according to the housing value and the specified depreciation rate is taken as the total output.

the total output of other service industries is calculated according to the following two situations: first, profit-making units, that is, service units whose main goal is to pursue profits, and the total output is generally calculated according to the total realized operating income; Second, non-profit units, whose expenditures mainly come from national finance and other sponsors, or although they have some operating income, they can't make up for their own operating costs, such as public management and social organizations. The total output of such units is generally calculated according to operating expenses, that is, it is equal to recurrent operating expenses plus virtual depreciation, and operating surplus is not calculated.

intermediate input refers to the value of non-fixed assets goods and services consumed and used by permanent units in the production process within a certain period of time. Intermediate input, also known as intermediate consumption, reflects the transfer value used in the production process and is generally calculated at the buyer's price. Goods and services included in intermediate inputs must meet two conditions: one is to be consistent with the calculation range of total output; Second, it is one-time use in this period.

added value is the difference between total output and intermediate input, which reflects the final results of production and operation activities of various industrial departments in a certain period.
