For example, in terms of value added (the value of output after deducting the cost of materials and components), China, contrary to popular impression, is not yet the manufacturing center of the world. The Chinese produce about 15% of value added in world manufacturing, while the United States contributes about 24% and the European Union about 20%.
比如说，从产品附加值（即扣除了原料和组分成本之后的产品价值）的角度来看，与普遍印象相反，中国并不是全球制造业的中心。中国对全球制造业产品附加值的贡献只有15%，而美国却有24%，欧盟也有20%。
