In a survey of China’s military and economic status, Strategy Page mentions the perennial issue of unreliable official economic statistics for China:
Chinese officials are becoming more open about the problems they have getting accurate economic information for such things like annual GDP and unemployment rates. Apparently Chinese GDP has not been growing steadily at near ten percent a year for decades. Chinese officials do eventually (months or years later) get more accurate data and while Chinese GDP has actually been steadily growing over the last three decades the annual growth has actually varied from 5-15 percent. Chinese official policy was to keep everyone calm by issuing less variable annual growth rates. In short, the official numbers were doctored. For more accurate and immediate indicators of economic activity Chinese and foreign economists and business leaders use things like electricity production, railroad traffic and similar data that cannot be manipulated by local officials to make their city or province look more successful. Many financial exerts inside and outside China fear that all this official manipulation of economic data (an ancient practice in China) is masking some serious economic problems that could go sideways at any time and cause a banking crises that would paralyze the economy for a while and cause political chaos. It’s very much a crouching tiger and hidden dragon. This is an ancient phrase warning that behind seeming success and talent lurks the possibility of imminent disaster. Chinese are ever mindful of these bits of ancient wisdom.
