(1) Output value of
construction projects, that is the value of projects covered by the project
budgets;
(2) Output value of
installation projects, that is the value of the installation of equipment,
(excluding the value of the equipment to be installed);
(3) Output value of others, that is the output value of construction industry
excluding that of construction projects and installation projects. It includes:
output value of repair of buildings and structures; output value of
non-standard equipment manufacturing; overhead expenses received by contracted
enterprises to the sub-contracted enterprises and the completed output value of
construction activities that have no clear definition.
a. Output value of repair
of buildings and structures, that is the value created through the repairs of
buildings or structures, but does not include the value of buildings or
structures being repaired and the value of the repair of production equipment;
b. Output value of
manufactured non-standard equipment, that is the value of non-standard
production equipment including raw materials and manufacturing cost made for
the construction project (i.e., chemical plant; kettles or tanks used by
refineries; various fillers, triangle tanks, valves used by mines), and the
output value of equipment manufactured by subsidiary workshops.
Value-added of
Construction refers to the
final result of the activities of production and management of construction
industry in monetary terms in the reference period.
Starting from the 2004
economic census, value-added of construction is calculated by both production
approach and income approach, with the income approach as the final approach,
where the calculation is based on the share of production factor in the
production process. Specifically, value-added of construction for census years
is calculated in accordance with the Programme
of Compilation of GDP and National Accounts for the Year of Economic Census,
and value-added of construction for other years is calculated in accordance
with the Programme of Compilation of GDP
and National Accounts for the Non Economic Census Years.

buildings completed during the reference period, and buildings under
construction and then suspended during the reference period.
Floor Space of
Buildings Completed refers to the floor space of buildings that are
completed in the reference period in accordance with the requirements of the
design, up to the standard for putting them into use, and have been checked and
accepted by concerned departments as qualified ones.
