província/região cresce mais que a tua!
A Xinhua explica tudo:

"An NBS report affirms that China's GDP grew 9.9 percent in 2005. If local government statistics are to be believed, then GDP growth averaged 12.39 percent in 2005.
The gap between the average GDP growth reported by local governments and the figure published by NBS has widened since 2000. This gap was 1.7, 2.0, 2.6 and 2.8 percentage points respectively in 2000, 2001, 2002 and 2003.
As the most important index reflecting regional economic growth, GDP growth is still the goal pursued by local governments and officials.
Since many corporations have branches in different provinces, their output and investment may be counted several times by different regions, leading to an exaggerated GDP figure, the newspaper said.
To avoid overblown figures, the central government is trying to restructure the official achievement evaluation system by introducing the new concept of green GDP, which would calculate environmental and ecological costs along with economic growth."
