Not being a statistician I'm probably not qualified to comment on the quality of Chinese economic data. I will note, though, that the Chinese Premier Li Keqiang (who isn't a statistician either AFAIK) has cast doubt on the veracity of China's data:
When China's premier was an up-and-comer in the provinces, he famously told US diplomats that he looked at indicators including electricity consumption and freight transport to gauge the true state of the world's second largest economy. According to a Wikileaks cable, Li Keqiang said such figures were more reliable than the government's own official GDP growth number.
But, maybe Li Keqiang is pulling our legs?
