There is no staggered heirarchy of levels of governance like the type we take granted in federated nations like Australia, Canada, Germany, the USA, etc. From the Imperial viewpoint, there is no federal-state-local style division of authority and sovereignty, nothing like a Sector-Subsector-System-Planet-Region-State-Local-etc. series of governmental 'slices'.
I think there is such a hierachy. However, I also think it is a highly variable one.
All the following is IMO. I like to think that very little, if any, of it is incompatible with established canon, but I know others disagree with me (Including L.E.W.)

Anyway, the primary relationship between a member world and the Imperium is governed by the treaty of membership. That, in turn, depends vey much on the history of the world. Some worlds may grown up around an Imperial outpost and been granted independence and self-government at some point. Such a world would have a treaty that allowed the Imperium to meddle quite a bit with local government, though always with some sort of 'plausible deniability'. Such as calling the Imperial governor an "advisor". And if such a world has subsequently grown very powerful, the Imperial Advisor may 'chose' not to exercise all his treaty-defined prerogatives.
Another world may have been strong and powerful long before it became a member of the the Imperium. Such a world might have a treaty that specified an even greater degree of autonomy than the average Imperial world enjoys.
At the next level the Imperium organizes itself into duchies. Each duchy has a great degree of autonomy vis-a-vis the central government, but that, too, is highly variable. One duchy may be founded on a powerful pocket empire that entered the Imperium 'en bloc'. Such a duchy could have a separate treaty with the Imperium of its own. The Imperium allows its duchies wide latitude in how they are organized. Some are run by their duke as centralized autocracies using his nobles as viceroys. Others are run as a cluster of counties. Others as enlightened monarchies, others again as constitutional monarchies.
In short, I like to think that if you want a Imperium that leaves the member worlds pretty much alone, you can find a duchy where the worlds have a higher degree of autonomy than most of the Imperium, and if you want the Imperium to manage the member worlds with a heavy hand, you can find a duchy where that's thet way it works.
And if you want the Imperium to be the guarantor of personal liberties against oppressive planetary governments (so that you can use your clone of Piper's Zarathustra
), why, you can find that somewhere too.
