Real gross domestic product
Real gross domestic product (real GDP for short) is a macroeconomic measure of the value of economic output adjusted for price changes (i.e. inflation or deflation). This adjustment transforms the money-value measure, nominal GDP, into an index for quantity of total output. Although GDP is total output, it is primarily useful because it closely approximates the total spending: the sum of consumer spending, investment made by industry, excess of exports over imports, and government spending. Due to inflation, GDP increases and does not actually reflect the true growth in an economy. That is why the GDP must be divided by the inflation rate (raised to the power of units of time in which the rate is measured) to get the growth of the real GDP. Different organizations use different types of 'Real GDP' measures, for example the United Nations UNCTAD uses 2005 Constant prices and exchange rates while the FRED uses 2009 constant prices and exchange rates, and recently the World Bank switched from 2005 to 2010 constant prices and exchange rates.
Historical GDP of China
This article includes a list of China's historical gross domestic product (GDP) values (with the latest to reach above US$14 trillion for 2018), the market value of all final goods and services produced by a nation in a given year. The GDP dollar estimates presented here are either calculated at market or government official exchange rates (nominal), or derived from purchasing power parity (PPP) calculations. This article also includes historical GDP growth.
In 1985, the State Council of China (SCC) approved the establishment of a SNA (System of National Accounting), using GDP to measure the national economy. China started to study and then implement a new system of national economic accounting. In 1986, as the first citizen of the People's Republic of China to receive a Ph.D. in economics from an overseas country, Dr. Fengbo Zhang headed Chinese Macroeconomic Research - the key research project of the seventh five-year plan, as well as completing and publishing the Chinese GDP data according to China's own research and calculations. A summary of the above events has been included in the book "Chinese Macroeconomic Structure and Policy" (June 1988) edited by Fengbo Zhang, and collectively authored by the Research Center of the SCC. This is the first GDP data which was published by China.
