With the rapid development of air transport industry，airport economy is becoming the power source of economic growth of international metropolis. Since it was approved to build the National Airport Economic Demonstration Zone in 2016，Guangzhou has vigorously developed its airport economy around the construction of an international aviation hub. The passenger and cargo throughput of the airport ranks among to the top in the world，and the overall strength of the airport economic demonstration zone ranks among the best in China. However，there are also some problems，such as the lack of optimization of development ideas，the need to improve the quality of airport economic development，the lack of functional play of comprehensive bonded zone，the lack of complete public service facilities，and the need to optimize the management system and mechanism. It is suggested to catch the “Two-zone” construction，“Two-city” linkage and other major historical opportunities，set up big hub，big airport，metropolitan development ideas，further optimize the development environment，straighten out the system mechanism，strengthen weak links in development，improve the quality of industrial development，comprehensively enhance the economic and population bearing capacity，and build new growth pole and regional integration development demonstration zone between urban and rural areas of Guangzhou and Guangdong-Hong Kong-Macao Greater Bay Area.
