鉴于不断增长的中间产品贸易，Johnson和Noguera(2012)对以增值贸易取代总贸易这一新概念开展了理论和实证研究。然而，他们没有处理新的增加值贸易差额与贸易总额差额之间的关系。这里提出的是，在两个国家和许多部门的情况下，新的增值贸易平衡总是等于总贸易平衡。我们利用格罗宁根大学编制的国际投入产出数据对这一命题进行了验证。在三个国家(中国、美国和世界其他地区)、多个行业的情况下，2010年以增加值计算的中国-美国贸易逆差或美国-中国贸易不平衡比以增加值计算的贸易逆差小23.5%，而以增加值计算的中国-罗贸易逆差比以总值计算的贸易逆差大94%。
In light of growing intermediate goods trade, Johnson and Noguera (2012) developed theoretical and empirical research on the new concept of trade in value added in place of gross trade. However, they did not deal with the relationship between the new value added trade balance and the gross trade balance. Presented here is that in the case of two countries and many sectors the new value added trade balance always equals the gross trade balance. We verify this proposition by using an international input-output data compiled by Groningen University. In the case with three countries (China, the USA and the rest of the world; ROW) and many sectors, the China-USA trade balance or the USA-China imbalance measured in value added for 2010 is 23.5% smaller than that in gross terms, whereas the China-ROW trade balance in value added is 94% larger than that in gross terms.
