For many years Hong Kong relied on its excellent harbour and proximity to China.  The position of Hong Kong has been strengthened from largely a manufacturing centre to an important global financial hub.  It is said that the ‘brains’ of many enterprises - the head office, design, sales and financial functions are located in Hong Kong, while the ‘brawn’, the manufacturing itself, is done north of the border.  Nowadays the service industries, especially financial and banking services, are both Hong Kong’s largest revenue earners and its major employer.
