The China miracle is ending. That miracle consisted of very exceptionally strong growth of the economy. By 2010, GDP per capita, adjusted for inflation, was 17 times higher than it had been in 1980. Consider that if living standards doubled in a generation, that would be pretty cool. But a 17 times increase? That can be called a miracle.
China’s growth has slowed in recent years, partly due to maturity. Extremely poor countries have the potential to grow rapidly. As they approach the level of developed countries, growth is harder and thus slows. See, for example, China Is Too Mature For Rapid Economic Growth.
Maturity is not the only issue. We need to delve into the source of the growth to evaluate whether it can continue.
