I used to live and work in Cambridge. In many ways it's a victim of its own success; people will, not unreasonably, argue that it's a beautiful little town of historic buildings, embedded in a primarily agricultural county of either prime agricultural land or protected wetland. They're not going to let you build Shenzen in Shelford no matter what the economic benefit might be. Meanwhile it's close enough to London that the property prices tick upwards to London commuter weighting.

(This is also why we have expensive electricity, because people oppose building any infrastructure. I'm coming round to the idea that there should just be county-by-county referendums where people have to pick either blanket allowing energy development or having a bill surcharge.)
