De-centralization of roman state

[Timianus]

A question that has probably been asked before, but of enough gravity to discus again;

In the 3rd century, possibly even earlier, the roman empire became less centred on Rome and Italy. Industry, trade, art, recruitment etcetera, to a large extent, took place in the outskirts of the empire. Cities like Leptis Magna booming.

Of course this had impacts on Rome itself. Why did these changes occur and what was their actual implication to life in the empire?

The emporers no longer ruled from Rome. They ruled from regional capitals. Trade, wealth, military etc. tend to coallesce at the seat of power.

The "implication" can be seen by the number of "breakaway" empires during the 3rd century crisis.
