Chinese Vice Premier Li Keqiang has affirmed achievements made in the second national economic census and urged delicate research and application of the results for better economic growth.

Li made the remarks in a congratulatory letter sent to a meeting, which was held this weekend to commend those who had made outstanding contributions to the massive survey starting from 2008.

The second national economic survey was a key investigation project on China's national conditions and strength and also a groundwork for scientific management and policy-making, Li said.

Li extended congratulations to groups and individuals who were commended. He said departments and census workers had worked hard in a creative way to achieve solid and accurate basic data and ensure the success of the census.

China started its second national economic census in October 2008. Policy-makers would use the results, published more than one month ago, to form the basis of the social and economic development blueprint for the 12th Five-Year Plan (2011-2015).

The National Bureau of Statistics started economic census in 2004, and it is conducted every five years.
