It's the buzzword our bureaucrats and politicians love. Hong Kong's claim to be a hub for more than 40 sectors, industries and activities - from Islamic finance to shopping - means it could almost be the world's hub for hubs.
But what is the city getting out of this hub hullabaloo?
Language experts say the trend to label cities "hubs" can give a metropolis an air of "globalisation" and can make something "more true". But they also warn that chronic overuse of the term risks diminishing its value.
Professor Adam Jaworski, a University of Hong Kong professor of language and communications, says hub is often now used as a synonym or replacement for "centre" and may be intended to define cities as "global".
"Many cities in the world are now competing for investment or more tourists so creating the imagery of a city as 'global' may be quite desirable," he said.
Most will agree that Hong Kong is a financial and transport hub. Throw in logistics, luxury brands and banking, thanks to our ports, love of high-end fashion and the pursuit of money.
