Abstract: The world urban agglomerations of Guangdong-Hong Kong-Macao Greater Bay Area are accompanied by the world airport group. The development of linkages and the construction of a world-class airport group require the dislocation development and benign interaction of the five major airports. Macau International Airport is an important part of Macao's integration into the Guangdong-Hong Kong-Macao Greater Bay Area. However, the airport has problems with the development of Macao, the airspace and air transport between Hong Kong and Zhuhai, and the land and environment of Macao. Therefore, the future development of the Macau International Airport will require efforts to achieve leap-forward development in the Portuguese-speaking countries, the close cooperation between Zhuhai and Macao, and the business jet industry. However, the issue over the expansion and reconstruction of the Macau International Airport has been controversial. The original site expansion, the new reclamation area, and the new construction of the enclave Huangmao Island are compared and analyzed to explore a plan that is in line with the long-term interests of Macao.

Key words: Guangdong-Hong Kong-Macao Greater Bay Area, world airport group, Macau International Airport, Huangmao Island
