Urban network research based on a specific type of industry has unique value and is essential for understanding the industrial pattern and urban function. Using the data of headquarters and branches of the Chinese A-share listed medicine enterprises, this article analyzes the characteristics of urban networks shaped by these firms. The results show that: (1) Most of the headquarters of medicine enterprises are concentrated in the coastal economic regions, including the Yangtze River Delta, the Pearl River Delta, and the Beijing-Tianjin-Hebei Region. Wuhan, Beijing, and Hangzhou are the important nodes in the network. (2) Five urban clusters stand out in the urban networks shaped by Chinese medicine enterprises. Moreover, the connectivity values in urban networks are significantly different, which are mainly formed by hierarchical diffusion and proximity diffusion, with strong connections between the developed city pairs and their surrounding cities. (3) Developed cities generally have high power and influence in the network. Meanwhile, some small or medium-sized cities with abundant resources have also played an important role in the network. (4) China's medicine industry is still in the early stages of internationalization. Only a few cities, such as Hangzhou, Shenzhen, Kunming, and Tianjin, have strong international connections. (5) The spatial structures of urban networks vary greatly among different subsectors of medicine enterprises, while Beijing, Shanghai, Wuhan, and other major cities play a central role in all subnetworks.
