With the rapid development of information, high-speed transport and other new technologies, the time and space are compressed while the elemental flows between cities have changed greatly. This reshapes urban system continually. The logistics system, which is promoted by e-commerce and high-speed transport system, plays vital role in shaping city networks. In particular, the connections between different cities are increasingly impacted by time distance of express but not space distance. Therefore, the comparison between the time distance of express and the traditional elemental connections is of great significance to understand the change of urban system.
Using the open application interface (API) data from the website of different logistics company, we obtained the express time between 337 prefectural cities in China and calculated the time distance of express based on the different transportation with different logistics companies. Then, we measured city transportation and economic connections. The transportation connection is reflected with the overall traffic flows through complex network methods, and the economic connection is calculated with the gravity model. Finally, the paper analyzed the relationship between time distance of express and the transportation and economic networks. This paper provides a new perspective to explore the coupling of new tempo-spatial factors with traditional element connections, and its potential effects on city hierarchies and connections.
