As China steers its economy away from a dependence on exports towards domestic consumption, its booming urban population will play a major role in driving growth in the world's second largest economy.

China's urban population, which has already surpassed rural residents, is expected to expand by 300 million over the next two decades. At the end of last year China's urban population stood at 690.79 million compared with 656.56 million in the countryside, according to its National Bureau of Statistic.
