As urban space becomes more complex through rail transit interconnectivity, this study investigates how to improve the spatial efficiency of metropolitan areas. Firstly, this article analyzes the research characteristics and shortcomings of synergy mode between interconnecting rail transit network and urban space through bibliometric methods. Secondly, by incorporating the concepts of networks and mobility into theoretical research and using multilevel network efficiency as the starting point, this study examines the key factors in synergistic development of network structure and function between rail transit and urban space. Based on this analysis, the Interconnection 2.0 model for synergistic development between rail transit and urban space is proposed, with the synergy relationship strengthened through network structure connectivity, network nodes, and element flow. Finally, combined with case analysis, this paper prospects the future development direction of interconnection at a higher stage in China. Theoretically, the study focuses on network hierarchy and nodality as well as the interaction between flows. In practice it provideds improves recommendations for improving the network connectivity and coupling of multilevel rail transit hubs. The research results provide a reference framework for the theory and practice of synergistic development between rail transit and urban space.
