"the country will spend somewhere between $125 billion and "$250 billion on infrastructure expansion and subsidies in the next eight years—between 3.5 and 7 percent of Germany's 2011 GDP"
The sentence is a bit confusing but I think they mean this:
~5% of 2011 GDP / 8 years = ~0.6% 2011GDP per year.
