Don't forget that Hong Kong is also a major financial hub, with the 6th(?) largest stock market in the world, and when the HK-Shanghai Stock Connect goes live in the coming weeks it'll be the second largest exchange in the world. Many western banks also do business in Hong Kong. The worst thing that would happen to Hong Kong is for the financial sector to leave - HK currently enjoys an average income 5X higher than mainland China, and higher than many western cities even.
