What was the effect of constantine moving the capital to constantinople?

Constantine's establishment of his new capital at Constantinople made it possible to more effectively administer the Roman Empire, which by then had its richest, most vital, and most productive provinces in the east, but it also accelerated the division of the empire into distinct eastern and western spheres. Moreover, the establishment of the capital at Constantinople is thought by some to have hastened the decline of the Roman system, since it deprived the empire of its founding myth.
