Global cities are competing with each other to be the most innovative by combining many kinds of intelligence, such as that of technology and of people with different talents.

"Urban innovation is a global agenda because everybody, from many different countries, tries to solve various urban problems together," said Heizo Takenaka, director of the Global Security Research Institute at Keio University, where he is also a professor in the Faculty of Policy Management

Urban innovation cannot be achieved without residents in many different professions and of various backgrounds, but problems arise in big cities: congestion, crime and pollution. Therefore, cities have to evolve using the dynamism of the talents and abilities of the people to maintain order.
