International function refers to the system of urban functionalities that transcend national boundaries and exert a distributive, radiating, and influential role globally in the fields of economics, hubs, culture, communication, and services. The Guangdong-Hong Kong-Macao Greater Bay Area, one of the most open and economically vibrant regions in China, holds a significant strategic position in the national development framework. The development of international functions in the Greater Bay Area bears considerable strategic value to the nation's advancement. This research analyzes the development of the international functions in the Greater Bay Area from the perspectives of international economy, international hubs, international communication and culture, and international services. It explores new ideas for the development and layout of international functions under the backdrop of international cooperation and exchange, contributing to the refinement of the theoretical system and development models of international functions. Moreover, it offers significant reference value for the construction of international bay urban areas and world-class urban clusters.
