Well, in a still nominally communist country like China the esthetics of power allow the Party to simply seize the means of production and "directly manage" a company as a way to achieve the Party's ideological goals. In a country like the US, which is a nominal democracy (but a Corporatist State regime in nature) the Party has to use indirect but equally powerful ways to do the same. But generally speaking, it will be content with "directing" the economy and letting the planning and managing to the private sector. The true power of the Corporatist State, like the 1920's fascists learnt, is that it hers to dictate what "the social/common/greater/ higher good" is. That is, where is the ideological line which, should the private sector dare paint outside of it, unleashes the crude coercion apparatus.
