With the increasing emphasis on coordinated regional development, transport and socioeconomic developments in China have taken a new turn in recent years. Based on the present and future integrated land transport network, the trend of city network accessibility and its impact on the change of regional development patterns in China were analyzed in this study by focusing on the construction of travel circles and regional balance. The results show that the completion of the existing planning can greatly improve the accessibility of China's city network and can largely support the construction of travel circles according to the shortest travel time. By promoting the development of hub-spoke organization mode and spatial cascading order, the existing planning can guide the multi-center and networking development of spatial structure and provide a basis for the coordinated and balanced development between regions. In the future, China's transport development should continue to optimize the supply structure of transportation services and improve the ability of the integrated transport system to serve the needs of people's daily lives and production.
