In the United States, quarterly GDP growth has fluctuated between -2.1% and 4.6% in the first half of 2014. Of course, Chinese growth almost surely fluctuates far more than the official numbers reveal, in part because local officials have incentives to smooth the data that they report to the central authorities.
对大部分国家来说，如此小的差异微不足道。在美国，2014年上半年季度GDP增长在-2.1%到4.6%之间波动。当然，中国的增长几乎肯定要比官方数字所揭示的波动更大，这部分是因为地方政府有动机将它们上报给中央当局的数据做平滑处理。
