Recently, the most popular topic among people in Zhongguancun has been: How far is Zhongguancun away from Silicon Valley (硅谷)? Can Zhongguancun be the next Silicon Valley?

People think that the day is not far when Zhongguancun will become a Silicon Valley. This is because Silicon Valley has two famous universities, Stanford and Berkeley universities, and Zhongguancun also has two universities, Peking and Tsinghua universities. Silicon Valley and Zhongguancun are gathering places for engineers. Silicon Valley has a group of well-known American high-tech companies including Intel and Hewlett-Packard, and Zhongguancun has famous companies such as Lenovo and Founder. Silicon Valley is good at science and technology, especially the information industry, while Zhongguancun is known as an electronics street.

However, Silicon Valley is still a far dream for Zhongguancun. Silicon Valley is a product of the market economy, while Zhongguancun is a government-led industrial group. Silicon Valley has an investment system of its own, while Zhongguancun is mainly a trading center for information products, a sales center and a market center. The Silicon Valley people have special and useful ideas. It’s important because of people’s innovation and adventure. All of the people have a good inter-personal relationship network, which enables Silicon Valley business starters to quickly get more money they need, find partners and grow.

The people in Zhongguancun think more about fund-raising, and give little thought to other factors. Some managers don’t understand the idea of market well. This can bring about many problems and can easily lead to failure. Now the basic task for Zhongguancun is to know the demands of the market and the users.

Now, many overseas talents who are returning home are people who once studied, lived and worked in Silicon Valley. A group of first-class universities have taken part in the development of Zhongguancun. It’s believed that Zhongguancun can become the next Silicon Valley, but it doesn’t need to copy Silicon Valley in every way. Zhongguancun can become a Silicon Valley with Chinese characteristics.
