Pearl River Megalopolis

The former city of Canton—where many of Sacramento’s Chinese originated from—is now the center of a developing megalopolis, as this story from New Geography reports.

An excerpt.

“In Southern China, the Pearl River Delta is giving rise to an urban super-power in the first rank.

“In 2005, the wealthiest metropolises were still led by the thriving urban agglomerations of the leading advanced economies in North America, Western Europe and Japan; that is, Tokyo, New York City, Los Angeles, Chicago, Paris and London. The scale economies of these metropolises are as significant as those of many national economies. For instance, the estimated GDP of Tokyo and New York City, respectively, was not that different from the total GDP of Canada or Spain, whereas London’s estimated GDP was higher than that of Sweden or Switzerland.

“In contrast with 2005, when most of the top-100 wealthiest cities were in the G-7 economies, by 2020 a third of these wealthy cities will be in the large emerging economies. However, such rankings are based on linear extrapolations, which tend to downplay growth differences and the impact of rapid urbanization. One of such rapid-growth regions is the Pearl River Delta (PRD), or Zhusanjiao – Southern China’s low-lying area where the Pearl River flows into the South China Sea.

“This area includes Metropolitan Guangzhou, a city of 10 million, capital of the Guangdong Province, which has more than 110 million people; Shenzhen, one of the fastest-growing cities in the world; and Hong Kong, one of the most competitive cities worldwide. In this region, urban planners are joining forces to create a massive Pearl River Delta Megapolis – which includes half a dozen cities of more than 4 million people each (Guangzhou, Shenzhen, Hong Kong, Dongguan, Foshan, and Jiangmen).”
