Cities are ecosystems for businesses and innovation. The strength of an urban center’s network of businesses, the talent of its citizenry, the stability of its political institutions, and the creativity of its cultural organizations all contribute to an environment in which existing businesses flourish and new businesses are born. A.T. Kearney’s Global Cities has been collecting data on these factors and others for the world’s most important cities since 2008. This 2017 Global Cities report, the seventh edition, testifies to the continued strength of many of the world’s largest cities in these domains.
