Gross domestic product
Gross domestic product (GDP) is a monetary measure of the market value of all the final goods and services produced in a period of time, often annually 
GDP (nominal) per capita does not, however, reflect differences in the cost of living and the inflation rates of the countries; therefore using a basis of GDP per capita at purchasing power parity (PPP) is arguably more useful when comparing differences in living standards between nations.
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.
