Maybe? I think military systems are interesting to look at when thinking about this question. The German military was famously centralized in WW2 leading to all sorts of chain of command issues while many of the Allied militaries like to push decision making authority down to more local units while providing overall strategic direction.
However, in governance, its much harder to measure "effectiveness" -- and every measure ends up becoming a target/goal of those being measured. Is it GDP? Sentiment analysis of social media for indicators of social discord? I don't really know, and neither does anybody else.
So some authority simply sets some desired set of strategic goals (2% GDP growth, 3% increase in high school graduations, average household income up by 2.3%, etc.) and then works to create conditions such that those are met.
But with more of a diversity of goals seems to require a diversity of executors of those goals since human attention is limited. This implies again an ability to delegate and so on and I'm not really sure if authoritarian governments can spare the attention to make sure each of the delegated executors can work on such a plethora of goals.
In business, the number of direct reports to the CEO, COO, VP and so on seems to indicate the number of strategic goals an organization can pursue at once. In most companies it seems to be only a handful as the ability of the CEO to direct many reports diminishes as there are more of them.
In the U.S. this need to spread focus works in the executive branch by appointing department heads (cabinet secretaries) who basically have a single overriding raison d'être for their existence (e.g. commerce, housing, transportation, etc.) with a set of strategic goals that those executives can focus on. In the U.S. that's something like 15 departments (plus a very large number of independent "establishments and corporations) which are more or less treated like a company might treat a subsidiary rather than a department.

China also has a complex system as well, much more complicated than I think outsiders give it credit for. It's not a surprise though, the ancient Chinese practically invented the idea of a bureaucracy [2]. I think the primary structural problem for China is not the simple notion of authoritarianism per se, but the parallel bureaucracy of the party structure.
