You do know that the majority of that stuff is the remit of local authorities?
Economic development is a local authority or combined authority responsibility. Tourism promotion is a local authority responsibility.
What businesses should move to these places, & what happens to the places they move from?
What support did you want for existing local businesses? Local authorities don't control business rates, or property rents.
What tourism?
Local authorities have always had limited funds and seldom fully financed large scale projects, such as new by-passes, new railway schemes, enterprize zones, "big" tourist/nature attractions, power plants, nor have they financed the govt's choice as to where to place it's public sector offices such as tax offices, DVLA, passport offices, etc. Local authorities usually only do the "small" stuff such as local bus routes, local roads, etc. It's always multi-agency working together that do the big infrastructure work. Things like new motorways or by-passes are done by the local authority, but they have to fight and compete for the central governmental funding to do it - your local council will never find the millions needed for a by-pass from within its own resources - not even in Brown's illusionary boom years.
As for tourism, if you hadn't noticed, it's actually booming in the Britain - the thing is though, it's changed, so the run down tourist resorts need central/governmental help to change their infrastructure to cope and develope to take advantage of modern tourism. Local authorities have never been able to afford to bulldoze huge areas of run down boarding houses or derelict fairgrounds - there needs to be central/governmental grants to provide the funds. At the very least, the government could help by not encouraging prisons and the DSS (or whatever it's called now) to send large numbers of people with social problems to live in those run down boarding houses which just makes the run down seaside resorts even worse (since they don't send any support to deal with their problems). Local authorities simply aren't and have never been in a position to do more than tinker around the edges with tourism - it needs a multi agency approach.
Government could extend business rate discounts, or even better, reform business rates so that, say, retail has a level playing field instead of paying far more per square metre than a warehouse. They could also reduce employers national insurance further for small businesses.
