China Begins Construction of Megacity Four Times the Population of New York

Construction began on a high speed rail system earlier this year in China’s Guangdong Province, marking the initial efforts to unite nine cities surrounding China’s Pearl River Delta and produce a metropolis unlike anything the world has ever seen. When the project–named “Turn the Pearl River Delta into One”–is completed some six years from now, the resulting megacity will cover 40,000 square kilometers (16,000 square miles) and, by today’s numbers, reach a population of at least 42 million. The metropolitan monstrosity will dwarf New York City, which spans 790 square kilometers (305 square miles) and has just over eight million people.

The nine cities to be merged include Guangzhou, Shenzhen, Foshan, Dongguan, Zhongshan, Zhuhai, Jiangmen, Huizou and Zhaoqing. One-hundred fifty major infrastructure projects will combine transportation, water, energy and telecommunications networks of the cities. A high-speed rail line will also be built to connect the megacity to nearby Hong Kong. The total cost is estimated at 2 trillion yuan ($304 billion).

City center residents will have a new flexibility that will foster the synergistic growth of the megacity. Ma Xiangming, a senior consultant on the project, says residents will have access to health care and other facilities they couldn’t feasibly reach before. He also expects that the interconnectedness will spread industry and jobs more evenly across the region and public services will be distributed more fairly. Shared resources are expected to lower phone bills by 85% and improve schools and hospitals. State of the art telecommunications networks will make it a smart megacity. For example, residents will be able to check ahead of time which hospitals are the least busy.



The high-speed rail already under construction will have 10 routes and connect the cities on the west side of the Pearl River to the cities on its east side. It marks the first line of what will eventually be a 29 rail, 1,500 kilometer system (3,100 miles) interconnecting all of the cities. Authorities expect the new rail to cut down what is now a 2.5 hour commute to 30 minutes and the maximum travel time between any two cities–or city centers within the megacity–will not exceed one hour.

The nine cities of Guangdong Province are special, as together they constitute China’s manufacturing epicenter, accounting for 10% of China’s total economy. “Turn the Pearl River Delta into One” is meant to roll these manufacturing all-stars into a single economic juggernaut that can compete with up-and-coming manufacturing competitors Beijing and Shanghai. To this end, Guangdong’s planners note that the goal of the project is not only to interconnect the cities physically, by way of rail, but also logistically. After being brought into the fold the different city centers will coordinate their decision-making. The price of gasoline and electricity, for example would be determined by a central decision-making body rather than independently within each city center.
