In short: strategic/geographic and political/ideological.

1) Strategic/geographic: Byzantium (renamed Constantinople) sat on a defensible peninsula at the entrance to the Black Sea and the Bosporus, controlling the main land and sea routes between Europe and Asia. That made it easier to defend the richer eastern provinces, respond to Persian threats, and control vital trade (and tax) flows—advantages Rome no longer offered.

2) Political/administrative and ideological: Constantine wanted a fresh seat of imperial power closer to the empire’s economic and military heartlands and out of the reach of the old Roman senatorial elite. Founding a new capital let him reorganize administration, legitimize his dynasty, and promote a Christian imperial identity without being tied to pagan Rome.

(He refounded Byzantium as Constantinople in 324–330 CE for these combined reasons.)
