Brief Introduction
Statistics on national
accounts include mainly four parts, namely, gross domestic product, input-output
table, flow of funds table and balance of payments table.
I.
Gross Domestic Product
Data on GDP are computed by the Department of National Accounts of the
National Bureau of Statistics (NBS) based on different approaches in the light
of the different features of various sectors, various expenditure structures
and different data sources. Gross National Income (GNI) can be calculated on
the basis of GDP on top of which is added the net factor income from the rest
of the world.
Data on GDP and
related indicators of the most recent year published in the Yearbook are not
final and are subject to changes when more information from financial data and
administrative records become available. Where a census has been conducted,
historical data of GDP of the previous years may also undergo change.
Gross
Domestic Product (GDP) is a measurement of value which changes depending on
changes of price and production. GDP at constant prices converts the gross
domestic product based on the current price into a value based on the price of
the base period. When adjusted for price changes, the values of two different
periods can be compared to reflect changes of both products and production
activities. GDP index is derived from the constant-price GDPs of the two
periods. As economy grows, changes will take place in the price structures of
various industries, and the base period for the measurement of constant-price
GDP thus needs to be adjusted every few years in order to better reflect the
impact of price change on the economy. Since China started GDP calculation,
seven constant-price base periods have been used, i.e., 1952, 1957, 1970, 1980,
1990, 2000 and 2005, and the current base period is 2005. That is to say, the
2006 GDP is calculated on the basis of the 2005 prices. As the calculation of
constant-price GDP is based on different base periods, the constant-price GDP
data in this yearbook shall also be announced in accordance with various
periods.
Regional data in this Yearbook are prepared from
the national accounts data provided by the statistical bureaus of the
provinces, autonomous regions and municipalities. The sum of the regional data
is not equal to the national total due to the decentralized accounting
approach.
II. Input-output Table
The Input-output table may be viewed as a table showing sector
relationships and balances or one showing sector output relationships.
Reflecting the sources of the input into, and the utilization of the output
from, the production by various industries of the national economy, the input-output
table takes the form of a chess-board shaped matrix format , and is used to
reveal, in quantitative terms, the interrelated and mutually dependent economic
and technological relationships among industries. The input-output table of
III. Flow of Funds Table
Similar to internationally accepted format, the Flow of Funds table of
IV. Balance of Payments Table
The Balance of Payments Table is compiled by the Balance of Payments
Department of the State Administration of Foreign Exchanges in accordance with
the 5th edition of the Manual on Balance of Payments prepared
by the International Monetary Fund.
