Even as the pace of growth slows, China is contributing more to the world economy than ever before, because its GDP today is $10.3 trillion, up from just $2.3 trillion in 2005. Simple arithmetic shows that $10.3 trillion growing at 6% or 7% produces much bigger numbers than 10% growth starting from a base that is almost five times smaller.
即使增长速度有所放缓，中国对世界经济的贡献仍比以往任何时候都要大，因为其GDP如今已达10.3万亿美元，而2005年只有2.3万亿美元。简单计算就可知道，10.3万亿美元增长6%或7%所得到的数字要比在基数只有五分之一大小的基础上增长10%大得多。这一基数效应也意味着中国将继续比以往任何时候吸收更多的自然资源，尽管其增长前景在趋弱。
