In addition to physical connections, the fast development of mobile communication technology has brought people closer via social network connections, and created stronger connections between cities in the virtual space. Meanwhile, communication technology has facilitated the emergence of urban big data, such as mobile phone data, social media, and remote sensing. This provides us with greater opportunities to study urban dynamics in finer spatial-temporal resolution.

The role of urban space in the network setting is understudied, and there are some critical issues that need to be explored:

How do multiple urban network layers connect markets, people and ideas?

How do such connections re-shape the system of open cities and urban spatial structure?

How does an urban network contribute to urban vibrancy and a city’s innovation capacity?
