Find out what makes China's Silicon Valley tick

The coffee shops, internet cafes and startup incubators in the Zhongguancun area of northwestern Beijing are packed with young and aspiring entrepreneurs. The atmosphere feels like the next Silicon Valley. But there are lots of attempts around the world to imitate the innovation nexus of northern California, why has Zhongguancun succeeded where so many others have failed?

One factor in the success of Silicon Valley and the much smaller Route 128 around Boston, is the presence of world-class technical universities.

Zhongguancun is centered around Tsinghua and Peking universities, which are often called China's MIT and Harvard, respectively. But, the nearby area may also be the biggest concentration of universities in the world.
