Since I got such excellent replies for my earlier economics query, thought I would try my luck once again.
The questions is, does allowing free capital flows into London cause a rise in prices for those in the hinterland?


Would not the high economic growth in London draw resources from other centres. Like pushing up salaries.

Depends on what you mean by "hinterland". If you mean that area within easy commuting disctance, then yes. If you mean the rest of the country, then, no.
... commuting distance pretty much covers everything within about 2 hrs train ride (each way). Yes, some nutters do do 4 hrs commute a day. That would cover everything from Cardiff in the West, Birmingham in the N, Peterborough, Norwich, all of E Anglia and all of SE UK. More realistically, anything up to about 1 hr 20 min train ride. Which is (very roughly) Bristol, still Birmingham, still Peterborough, Cambridge, Anything south of Ipswich in E Anglia and all of the SE and S coasts (across to about Bristol level).
