The main textile producing regions of Britain are the East Midlands， Yorkshire， Humberside， and Northern Ireland.
New industries include microprocessors and computers， biotechnology and other high-tech industries. There are three areas in Britain which have seen some high-tech industrial growth： （1）。the area between London and South Wales， （2）。the Cambridge area of East Anglia and （3）。the area between Glasgow and Edinburgh in Scotland. The third area is the most spectacular of the three and is now often referred to as the “Silicon Glen”。 By the end of 1985 half of Britain‘s microchip output was estimated to have come from Scotland.
The reasons behind the decline of Britains textile industry are：
（1） Exports of textiles have not competed well with those of other foreign producers who have managed to produce cheaper goods.
（2） There has been a rise in cheaper imports of textiles to Britain from foreign producers.
（3） Poor and outdated management decisions have caused problem.
（4） Substitutions of human-made fibres have been made for natural fibres.
（5） An improvement of output per worker has been achieved， due to mechanization.
