现在,我国每年生产和消耗的钢铁、水泥、煤炭、化肥等都居世界首位。但 GDP却大约只有美国的1/7、日本的 1/3(按2003年数据推算)。这里面固然有汇率的因素,由于人民币币值低估而使中国的GDP 跟着低估。如果将投入产出表中用人民币计算的各项数据都转变成外国货币如美元表示的话,中间投入、增加值、总投入等都应同时转变成美元, 不管采用何种汇率,都不会改变投入产出之间的比例关系。所以,中国的增加值率或中间投入贡献系数较低是一个不争的客观事实。
Now, the steel, cement, coal and chemical fertilizer that China produces and consumes each year rank first in the world. However, the GDP is only about 1/7 of that in the United States and 1/3 in Japan (based on 2003 data). Although there are exchange rate factors in China, the undervaluation of the renminbi has left China’s GDP undervalued. If all the data in the input-output table in RMB are converted into foreign currencies such as the U.S. dollar, the intermediate inputs, the added value, the total inputs, etc. should all be converted into U.S. dollars at the same time, and will not change at any exchange rate The relationship between input and output. Therefore, it is an indisputable objective fact that the value added rate of China or the contribution coefficient of the intermediate input is low.
