　　【Abstract】 This paper offers an extensive summary of the direction and strategies for function optimization and improvement of Guangzhou. The summary concentrates on the significant preposition of determining how to further optimize and improve the function of Guangzhou as a comprehensive transportation hub in the context of the coordinated development of the Guangdong–Hong Kong–Macao Greater Bay Area. The summary is based on the development experience in New York, London, Tokyo, and other world-class bay areas and the characteristics of different construction and development stages of Guangzhou as a hub. Firstly, the paper identifies four major shifts in the function of the comprehensive transportation hub in the new era, through an analysis of the flow characteristics of population, economy, industry, and other elements in the Guangdong–Hong Kong–Macao Greater Bay Area and Guangzhou. The four major shifts include the shift from competition and cooperation to coordinated development, the shift from scale expansion to quality improvement, the shift from facility connection to integrated services, and the shift from an emphasis on efficiency to a focus on effectiveness. Secondly, by summarizing the urban development experience of world-leading bay areas, the paper proposes that six aspects of comprehensive transportation hub function improvement should be prioritized: global connection capability, hub carrying capability, interconnection capability, capability to provide integrated services, capability to support the urban economy, and sustainable development capability. Finally, the paper establishes an indicator evaluation system with 18 key indicators of the function optimization and improvement of Guangzhou as a comprehensive transportation hub based on the six capabilities. The proposed method can help evaluate the challenges faced by Guangzhou and put forward corresponding suggestions, including improving the city level of Guangzhou as a hub, co-building and sharing resources, innovating integrated services, and strengthening the hub economy. The measures are expected to facilitate the high-quality development of Guangzhou.
