The advancements in urban network research under the backdrop of rapid globalization and information technology development were reviewed and summarized, with a focus on the evolution of space of flows theory and its impact on the development of urban network studies. Through a literature review, empirical research progress was synthesized in four five areas: types and measurement methods of flow elements, research differences across regions and scales, data challenge strategies, applications of total network analysis and individual network analysis, as well as classification of scientific issues and their practical case applicationsapplications. The conclusion identifies current research problems and future research directions are proposed in order to foster deeper exploration in the field of urban networks.
