Richard Florida wrote an interesting article a while back in which he suggested that government policy makers would be wise to forge new ideas based on the economic and innovation potential of so-called mega-regions around the world. Much more so than countries or cities, he contends, mega-regions are actually the prime drivers of the global economy.
While there are 191 nations in the world, just 40 significant mega-regions power the global economy. Home to more than one-fifth of the world’s population, these 40 megas account for two-thirds of global economic output and more than 85% of all global innovation.
The world’s largest mega is Greater Tokyo, with 55 million people and $2.5 trillion in economic activity. Next is the 500-mile Boston-Washington corridor, with some 54 million people and $2.2 trillion in output…
Mega-regions are the true force driving the rise of emerging economies. Some 40% of Brazil’s total economy is made up of a corridor stretching from Rio to São Paolo. Russia is propelled by the Moscow mega. India’s economy is shaped by the mega-regions of Bangalore and Mumbai.
China is not our real competitor. Rather, we should be thinking about the great mega-regions around Shanghai, Beijing and the Hong Kong-Shenzhen corridor, which account for roughly 43% of the output of the entire country.
Florida discusses several ways in which governments can support the innovation that arises from mega-regions, from promoting free trade to developing urban policies meant to improve infrastructure and facilitate “greater cross-border flows of goods and people.” It’s a thought-provoking piece that is worth a look.
