It means that their economic policy was never fully defined. Unlike the Italian fascists the Nazi's never really said what they were going to do with their economy. Their economy also shifted markedly over the years they were in power depending on the political climate.
As such it's not really possible to find an economic model which matches that of Nazi Germany because Nazi Germany didn't really have one.
I don't really understand what you're asking for, the economies I gave you as examples range between partially socialised (ie. government run schools, healthcare etc.) to the much more socialised (government runs much of the businesses and production). What are you looking for?
