China Is Creating a 'Greater Bay Area' to Rival Silicon Valley. What Will It Mean for Hong Kong?

The world’s longest open sea bridge starts in Hong Kong.

It opened with little fanfare and a short ceremony last October. President Xi Jinping of China marked the occasion with a single-sentence speech delivered from an artificial island built to house one of the bridge’s three immigration check points. Stretching 34 miles, including the length of two underwater tunnels, the $15 billion forked bridge connects Hong Kong to the gambling haven of Macau and the mainland Chinese city of Zhuhai.

Although Xi didn’t travel across the Hong Kong-Zhuhai-Macau Bridge himself, the connector is symbolic of one of the president’s most ambitious policy plans to date: a scheme to unify 11 Chinese cities into a single sprawling megalopolis, covering 21,600 square miles, housing 70 million people and called the Greater Bay Area (GBA). For Hong Kong, closer integration could help open a vast market that sits just north of its border. For China, Xi hopes the GBA will rival San Francisco’s Bay Area, where financial services, shipping and innovation have formed a rich economic ecosystem.

Xi’s plan, much like the bridge, is controversial. In Hong Kong, opponents of Beijing’s increasingly heavy-handed influence over the former British colony’s autonomy deride the bridge as an “umbilical cord” tying Hong Kong to the mainland. They fear the Greater Bay Area (GBA) will erode the political freedoms granted to the Hong Kong Special Administrative Region (HKSAR) when it was returned to Chinese sovereignty in 1997.

Currently Hong Kong operates its own judiciary, which is dictated by a mini-constitution called the Basic Law. The Basic Law grants Hong Kong the regulatory freedoms and political stability it needs to operate as a hub for international business and finance – a springboard for Chinese companies expanding overseas and an entry port for international firms targeting China.

However, the Basic Law is only guaranteed to be in effect for 50 years from the date of the handover. Beijing could opt to extend the “one country, two systems” principle, which serves as the basis for the HKSAR’s unique privileges, beyond the 2047 expiration date, but it might not. With no guarantee, the Greater Bay Area policy offers the best insight into what Hong Kong’s future role in the world will be.

What is the GBA?

The Greater Bay Area is comprised of nine cities in Guangdong – the southern province where Deng Xiaoping launched China’s policy of economic reform 40 years ago – plus the two Special Administrative Regions of Hong Kong and Macau. According to research from HSBC, the GBA generates $1.5 trillion in GDP each year, which is 12% of the national total for China, or roughly the same economic output as all of South Korea.
