You could also approach the problem from the other end. Have the state offer a reduced business tax cut rate for open offices and employing people in underdeveloped cities. Similarly at the other end of scale increase business taxes for companies that insist on expanding in overdeveloped cities. This is common in Europe where business parks are setup in underdeveloped areas to encourage investment from outside. Usually these are coupled with reduced tax deals as it's in the governments interest to have people in the area in work rather than claiming unemployment.
