To be sure, intensity of use has fallen for some commodities, like gold and nuclear energy; but for others, such as aluminum and coal, it has risen since 2000 or, as is the case for copper and oil, declines have slowed markedly or stalled at high levels. As the composition of China’s economy continues to shift from investment to consumption, demand for commodity-intensive consumer durables – cars, mobile phones, indoor plumbing, computers, and televisions – will rise.
实事求是地说，一些商品的强度已经有所下降，比如黄金和核能；但铝和煤的强度自2000年以来有所上升，铜和石油的强度则下降缓慢或维持在高位不变。随着中国经济的组成从投资向消费转变，商品密集型耐用品——汽车、手机、室内水管、计算机和电视机等——消费量将会增加。
