The document discusses the changing location of industry in the UK. It introduces the concept of a footloose industry, which is not dependent on local raw materials and can locate freely. As an example, it examines the high-tech industry that has developed along the M4 motorway corridor from London to Bristol. Key factors attracting footloose industries to the M4 corridor include good transportation access via roads and airports, proximity to universities and research centers, and government incentives in an attractive countryside environment.
