Chinese growth has been relatively volatile around this trend, reflecting stop-go cycles of state response to inflation through aggregate credit management. The Indian economy broke from its average post-Independence annual rate of around 3 per cent growth to achieve annual rates of more than 5 per cent from the early 1980s. It is only in the four-year period before the global economic crisis starting late 2008 that the Indian economy grew at rates in excess of 8.5 per cent per annum, coming close to the Chinese average. The investment rate in China (investment as a share of GDP) has fluctuated between 35 and 45 per cent over the past 25 years, compared to 20 to 26 per cent in India (very recently increasing to 35 per cent).
