Youngsun, you are writing about a concept I mostly support 
I never played Imperialism, so I have no hints about how it work, still I'm not sure the infrastructure (meaning roads or railiroads) will be the key to solve ICS problem. Roads are already useful to faster units movement, so most of players already build them. If you put a road/r.r. path between countries as a plus point to make a trade pact (mine suggestion on other post), it could add something, still not enough.
I agree about resources that must be on regional level, but I'm not sure to like some SMAC end games where a player can have hundreds od supply units sucking resources out of planet side by side as a carpet
Your proposed interface about drilling down from province to cities is somewhat crude and unefficient, but that's not the point.
Province borders can have different radius, taking in the misure the faster unit movement available, the natural borders (mountains, rivers), the borders pacts between civs etc.
Oh, I must add some other apolytoner suggested we must bring into the equation the technology age, to favour early easy development of Civ but keeping the support on a city level until the concept of whole nation (and the state of transports, politics and so on) let the support model switch to a more advanced (national) one.
On a different subject, Adm.Naismith doesn't stand for Adam, but for admiral Naismith, a fiction (and very smart
) main character of some science fiction books written by Lois McMaster Bujold. Good, funny reading, IMO.
