For example, in the German case, the relevant figure amounts to roughly 75% at the current juncture, compared with just over 60% in 1990.  b)  global trade is also boosted by the ongoing internalisation of production structures. These are most visible by looking at the growing stock of FDI.
According to UNCTAD figures, worldwide FDI stocks amounted to over 26% of world gdp in 2006. In 1990 the corresponding number was less than 9%. In Germany the relevant numbers increased form 8.9% to nearly 35%. The German development roughly corresponds to the Norwegian numbers (9.4 %/36 %).
