My view of the Nazi economic policy is pretty simple - they would do whatever they though was of benefit to the Nazi Party, which to them was pretty much the same thing as the nation. If they needed to force a business to do something, they would do it. If leaving a business alone to do what it did was beneficial, they'd do that. The policy was simply whatever it took to push the Nazi agenda and the Nazi war machine forward. Overall, their policies might be considered socialist, but they really didn't have a consistent economic theory or ideology that they ran on.
Couldn't have said it better.
Unlike most (if not all) other political ideologies, economic policies were
not a central part of Nazism. It was merely a useful tool to achieve their actual goals... which didn't have much to do with the economy (but with "race", "nation" etc.).
Of course, in their earlier days (around 1920) they had some of these economic proto-theories you could perhaps call "socialist". But such theories are also explainable with a non-economic approach, because many companies, banks etc. in the Weimar Republic were owned by Jews... or at least this is what the Nazis wanted to believe. As a result, there was a direct connection between their anti-Semitism and their "socialism".
Once the Nazis were in power, those theories didn't play much role anymore. In the few cases where Jews were indeed on the board of major companies, they were forced out. As far as the remaining "Aryan" businessmen were concerned... those were sometimes cuddled and sometimes tightly regulated by the Nazis, depending which helped their goals best.
And you have also to keep in mind that the Nazis were also strictly anti-labor union during the Weimar Republic, something you don't call "socialist" usually.
