McKinsey recently published a report called Digital globalization: The new era of global flows.
The overarching thesis is that we are transitioning to a data-driven global economy:
“Flows of physical goods and finance were the hallmarks of the 20th-century global economy, but today those flows have flattened or declined. Twenty-first-century globalization is increasingly defined by flows of data and information. This phenomenon now underpins virtually all cross-border transactions within traditional flows while simultaneously transmitting a valuable stream of ideas and innovation around the world.”
One of the benefits of this shift is that it has become easier for emerging economies and individuals from all around the world to participate.
Of course, not all countries and cities are participating equally. In their report, McKinsey ranks the top cities according to five global flows. In each case a proxy was used:
“Unfortunately, data on global flows are not available at the city level. However, we have obtained data that serve as proxies for each of our five global flows. Container port volumes approximate goods flows; airport passenger volumes serve as a proxy for goods, service, and people flows; the ranking of cities in the Global Financial Centers Index by the Z/Yen Group provides an indication of financial flows; the number of foreign-born residents in a city measures people flows; and Internet bandwidth approximates data flows.”
