New York, Paris, Milan, Peckham... the city you base your business in can make all the difference to whether or not some day you will be a billionaire. So where should big business be heading, and where does the UK feature?
A study by the Economic Intelligence Unit has identified the ten most competitive cities in the world. It identified competitiveness as the ability to attract business, talent and visitors - by rating them on a whole host of attributes, from economic strength and human capital to institutional effectiveness and social and cultural character. Overall, it reveals it's not just size that counts - and that when it comes to the decline of the West - there's life in the old dog yet.

However, there are some worrying signs for the future - not least the score of 18th for human capital - which demonstrates a lack of talent. Mayor Michael Bloomberg blames the country's immigration policies for keeping skilled professionals out.
Second place is a strong finish for the UK's most competitive city - Birmingham is the next placed city in the UK and makes it to number 37.
London benefits from real strengths in financial maturity, social and cultural capital. It also takes the top spot for global appeal.

Human capital is a real strength for Hong Kong, with the second highest score overall (after Dublin).

Added to that, strengths in financial maturity, and sixth place for global appeal, push it into equal fourth place.
This takes third place overall for global appeal. Tokyo also makes it into the top ten for financial maturity, economic strength and physical capital. It certainly capitalises on its size - with an economy well over a trillion dollars.
