China initiated a key strategy in 2014 to coordinate the development of Beijing, Tianjin, and Hebei province, a regional city cluster called "Jing-Jin-Ji," to create a model with a better economic structure, cleaner environment, and improved public services.

Zhongguancun, Beijing's technology hub, has become an important engine for scientific and technological innovation in the city cluster.

In 2015, Zhongguancun established its first innovation center outside Beijing in neighboring city Baoding, north China's Hebei province.

Today, the Baoding-Zhongguancun innovation base has 400 enterprises, with more than half of them from Beijing. Seeing career opportunities, many young people have left Beijing for Baoding.

In 2016, the Binhai-Zhongguancun Science and Technology Park was officially unveiled in Beijing's neighboring port city of Tianjin.

Now, the park has registered more than 2,000 enterprises.

A total of 35 national high-tech enterprises are also registered here.

By the end of last year, enterprises in Beijing's Zhongguancun had set up more than 8,600 branches in Tianjin and Hebei, and the total amount of technology contract transaction between Beijing and Tianjin, Hebei exceeded 140 billion yuan ($21.63 billion).
