　　BEIJING, Aug. 25 -- A Chinese official said Wednesday that the conclusion in a widely-circulated report claiming real income levels of Chinese households are much higher than official data is "unreliable".
　　"There are many flaws in the report, such as the way to choose survey samples and make calculations, and the final result is significantly higher (than the actual level)," said Shi Faqi, an official with the National Bureau of Statistics (NBS), in a bylined article posted on the bureau website.
　　Shi's article was commenting on a report by Wang Xiaolu of the China Reform Foundation, a Beijing-based economic development research group. The report claimed China's average urban household income was 90 percent higher than official data, which it claims does not cover "gray incomes" such as kickbacks, bribes and the like.
　　The survey that led to Wang's report covered only 4,909 households, about 7.6 percent of that investigated by the NBS survey, and thus the results based on the survey were not reliable, Shi said.

　　According to calculations using the model, the country's urban per capita disposable income reached 32,154 yuan (4,728.5 U.S. dollars) in 2008, double the NBS figure, while total urban incomes would then account for 73.9 percent of GDP. "Such results are apparently not reasonable," Shi said.
