China's economic growth will steadily regain speed in 2013 despite global economic uncertainties, according to a blue paper released on March 26.

Thanks to a proactive fiscal policy—or increased spending in a number of areas—and a prudent monetary policy introduced in 2012 along with a more coordinated economic growth model propelled by consumption, investments and exports, the momentum of China's economic growth will continue, says the paper, which was published by the Social Sciences Academic Press.

Despite the positive outlook of China's economy, the blue paper warns that the country needs to advance its opening up and reform and restructure its economic growth model to ensure sustainable growth.

The blue paper, which focuses on the development of the BRICS nations—the emerging economies of Brazil, Russia, India, China and South Africa—says China remains the last country in the group where the service industry accounts for less than half of its economy.

State-owned enterprises still make up the bulk of the services sector and the share of non-state operators in the market is small, leading to insufficient competition, says the paper.
