The importance of metropolitan regions has been recognised by economic experts internationally, and is a concept to which Scottish Enterprise has given careful consideration.
A metropolitan region approach is also reflected in the proposed strategic development plans introduced by the Planning etc (Scotland) Act 2006. These will be required in the four city-region areas in and around Glasgow, Edinburgh, Dundee, and Aberdeen. Strategic Development Planning Authorities, involving the local authorities in each city-region, will be required to set out in their plans a vision for the development of their region, and a spatial strategy. They will also be required to prepare an action programme for its delivery. This should set a spatial planning framework for stimulating sustainable economic growth.
