China ‘exaggerated’ GDP data by 2 percentage points for at least nine years, new study says
- Mainland has overestimated its nominal and real growth rates by about 2 full percentage points on average between 2008 to 2016
- Calculations suggest that the current nominal size of the economy is about 18 per cent lower than the official level of US$13.4 trillion at the end of 2018
China has overestimated its nominal and real growth rates by about 2 full percentage points on average between 2008 to 2016, with the miscalculation increasing each year, according to a new study published on Thursday.
The results indicate that the actual size of China’s economy at the end of 2018 was well below the government’s official estimate.
It also raises questions not only about the quality of economic data from the world’s second largest economy, but also the willingness of the government to take the steps necessary to accurately report information.
Using the study’s findings and applying them to government figures starting with the level of nominal gross domestic product (GDP) at the end of 2007 and the growth rate for 2008, calculations by the South China Morning Post show that the current nominal size of the Chinese economy is about 18 per cent lower than the official level of 90 trillion yuan (US$13.4 trillion) at the end of 2018.
The calculation assumes that the government’s official 2017 and 2018 nominal growth rates are overestimated by 2 percentage points, as suggested by the study.
