Talk:The Paradox of the Chinese Superpower/@comment-27815744-20181124085734

China does not always overestimate GDP growth- this just isn’t possible as it would lead to large inconsistency down the line which inevitably will cause economic collapse. What it does is “smooth” gdp growth to look more consistent.

GDP growth naturally fluctuate up and down - this is just how it works. Many countries, including China, smooth this curve to the average value, so at any time the GDP announced does not fluctuate too much from the actual value, but to investors the economy looks more stable then it is.
