The authoritarianism of corporations cannot be compared that of a state, workers might not get a vote but they are free to leave a corporation in a free society, and corporations do not have the power to arrest people (I'm aware of exceptions). They're also subject to much higher selective pressure than states which helps keep them in check.
I was talking about overall and general efficiency, authoritarian states are less economically, militarily and scientifically efficient than their freer counterparts. They may be effective at pursuing specific policy goals, and there are authoritarian states that have sufficient mass that they can achieve a lot in any given field, but they are usually more effective at giving the appearance of effectiveness that they are than actually achieving anything. Either way, effectiveness is not efficiency.
