A favorable assessment cannot rest on the fact that the overall German value-added in exports has been growing because this is simply an effect of the German specialization in export-related production. When a country specializes in a certain area, capital and labor move into that area at a rate faster than they move into other areas – indeed, the growth of export-related sectors may come at the cost of a decline in other areas.
这是好事还是坏事？鉴于出口产品中的德国附加值总量增长仅仅是由于德国专门从事与出口有关的生产的效应，因此，不能因此而得出较佳的评估。当一个国家专门从事于某一个领域之时，资本和劳力就会比其他领域更快地流向这一领域。事实上，出口相关部门的增长的副作用是其他领域的下降。简而言之，德国存在着过度专业细分。
