GDP rating system a world first

BEIJING - The Chinese Academy of Sciences published the country's first quality assessment system for GDP on Friday.

The assessment system rated the 2010 GDP for 31 provinces by their contribution to local economic growth, social development, environmental quality, people's living standards and government management.

After rating the five criteria, the researchers calculated a final score for each province's GDP, with Beijing scoring the highest and the Ningxia Hui autonomous region the lowest.
