Gross Output Value of Construction refers to the sum in monetary terms of construction products and services completed by construction enterprises during a given period of time. It includes:
    (1) Output value of construction projects, which is the value of various projects covered by the project budgets;
    (2)Output value of equipment installation projects, which is the value of the installation of equipment;
    (3) Other output values, which are output values other than output value of construction projects and output value of installation projects, including output value of house and building repair, output value of non-standard equipment manufacture, management expenses received by overall contractor enterprises from subcontractor enterprises and output value completed in unclassified construction activities. ª±
    ¢ÙOutput value of house and building repair is the value created through the repairs of houses and buildings, excluding the value of houses or buildings being repaired and the value of the repair of production equipment.ª±
    ¢ÚOutput value of non-standard equipment manufacture is the value of non-standard production equipment with unique specifications (including raw materials and manufacturing costs), and equipment manufactured by subsidiary workshopsª±for construction projects contracted by construction enterprises.
Output Value Completed refers to the value of unit project completed, which has come up to the designed standards for putting into use and has been checked and accepted as qualified project by related departments.ª±
    Value-added of Construction refers to the final results in monetary terms of the production and management activities of construction enterprises in the reference period.ª±The value-added of construction is calculated with two approaches: one is the production approach, which calculates the total value of construction minus the total intermediate consumption of construction; the other is the distribution approach (income approach) from the perspective of income, which calculates the sum of income of various production factors in the production process, including depreciation of fixed assets, labors¡¯ remuneration, net taxes on production and operating surplus. Prior to 2004, the value-added of construction was calculated with an old distribution (income) approach according to the statistical reporting system of construction. Since 2005, the new income approach is used to calculate the value-added of construction.
    Floor Space of Buildings under Construction refers to the floor space of buildings under construction during the reference period, including newly started buildings, buildings started earlier and continued into the reference period, buildings suspended in preceding periods but resumed during the reference period, buildings completed during the reference period, and buildings started and then suspended during the reference period.ª±
    Average Number of Persons for Labor Productivity Calculation refers to the average number of persons actually employed in the construction enterprises (units) and engaged in related activities of construction in the reference period, including non-staff personnel engaged in the construction activities of the enterprises (units), but excluding personnel employed in social service institutions of the enterprises and those receiving remunerations therefrom but engaged in activities basically irrelevant to the production of the enterprises.
    Number of Engineering Technical Personnel Employed at the Year-end refers to personnel capable of and engaged in engineering technical work and related management.
    Total Profits refer to the surplus of various incomes in the production and operation of the enterprises after deducting all expenses.ª±This reflects the total profits or losses realized by the enterprises in the reference period, including profits from operation, income from subsidies, net investment earnings and net income from activities other than operations.ª±
    Taxes and Extra Charges on Project Settlement Accounts refer to business tax, city maintenance and construction tax and extra charges for education calculated and paid with business tax, which should be borne by the enterprises obtaining project settlement incomes from the production activities of construction.ª±
    Taxes from Management Expenses refer to the taxes which should be borne by the enterprises from management expenses, including property tax, land use tax, vehicle and vessel use tax, and stamp tax.
    Total Pre-tax Profits = Taxes and Extra Charges on Project Settlement Accounts + Taxes from Management Expenses + Total Profits
