Unfortunately, China’s data are not nearly as reliable as those measuring a developed economy, which makes it difficult for anyone to be sure of what is happening. Electricity usage is typically one of the most reliable measures of growth; but, with the economy shifting toward services, and with many energy-intensive industries such as cement and steel production slowing down, it is perfectly possible that slow electricity growth is simply a symptom of rebalancing.
不幸的是，和测量发达经济的数据相比，中国的数据可靠性更低，这让人更难确定中国正在发生什么。用电量通常是最可靠的增长指标之一；但是，随着经济向服务业的转型，以及许多能源密集型行业（如水泥和钢铁）生产放缓，电力增长缓慢完全有可能只是再平衡的现象。
