The construction of Guangdong-Hong Kong-Macao Greater Bay Area is an important national development strategy，a major measure to promote the overall opening up of China at this stage，and an important practice to promote the development of the cause of “one country，two systems”. The construction of Greater Bay Area is inseparable from the support and development of the airport group. Promoting the coordinated development of airport of Greater Bay Area is the key measure. There are seven airports in Guangdong-Hong Kong-Macao Greater Bay Area，including Hong Kong International Airport，Macao International Airport，Guangzhou Baiyun Airport，Shenzhen Bao’an airport and Zhuhai Jinwan airport，as well as Huizhou Pingtan airport and Foshan Airport. There are huge differences in the scale，function and development orientation of each airport. The airports of Guangdong-Hong Kong-Macao Greater Bay Area has certain advantages in economic hinterland，industrial growth and geographical location，but there are certain contradictions in management system，competition，resource allocation，airport operation，etc. In this regard，based on the development experience of New York Bay area，San Francisco Bay area and Tokyo Bay area，this paper puts forward corresponding countermeasures and suggestions from the aspects of overall management，market positioning，traffic mode and resource allocation.
