This paper analyzes the reasons why high-tech enterprises are located in the periphery of central cities.

A good urban living environment can bring more creativity.

First, a good urban living environment can better obtain the "spillover effect" of knowledge. For innovative activities, interpersonal contact and cross-enterprise mobility can promote the effective transfer of knowledge. For example, face-to-face contact and discussion at lunch or golf course is the key to the continued success of Silicon Valley's technology start-up industry. Second, it is more convenient for cities to recruit innovative talents. High-quality innovative talents are often in central cities with good living environment. The closer the office is to the bustling city block, the better the supporting facilities, and the more benefits it can get from the workspace. Knowledge workers are attracted by shorter commuting distance, more and better supporting services and pedestrian streets.
