The article also discusses how the growth in each country has been in different sectors:
According to conventional wisdom, Chinese workers have shifted largely from farming to factories, whereas India's growth has been driven largely by services, from call centres to writing software. In fact, jobs in services have expanded more strongly in China than in India. Since 1993 the rate of increase of China's service-sector jobs has been four times that in industrial jobs and has exceeded that in India. China's real output of services has not only grown almost as fast as its industrial output, but also faster than India's services. Indeed, a larger proportion of workers is employed in services in China than in India. However, the share of services in GDP is much smaller in China (33%, against India's 50%), because Chinese industry is so much more productive.This article provides a deeper look at increases in GDP and a little background on the rapid growth of India and China.
