Yes it is a mixed economy - there are even free market pockets - though its predominately Socialist Capitalism. The term Corporatism implies government interference unfairly supporting big business and this is a kind of Socialism anyway. Socialist Capitalism and Socialism are synonymous.
When you say "mostly capitalism" - that phrase is too ambiguos to convey clear meaning. Do you mean mostly Free Market Capitalism or mostly Socialist Capitalism? There is a huge difference - intereference vs no interference.
To clarify you must distinguish whether you mean Free Market Capitalism or Socialist Capitalism. Just because businesses are privately owned doesn't mean this is Free Market Capitalism because these businesss are forced/intimidated to make their private accounts transparent. The more businessess are interferred with the more Socialist Capitalism there is and the less Free Market Capitalism there is.
