After we analyze the difference and similarities between them,the concept of airport economic area is further clearfied. A case study of the hub-airport in the Yangtze River Delta is conducted. The determination of the airport economic area goes as follows. Firstly, if urban built-up areas adjacent to the airport area are formed or not is one of issues considered. Secondly, according to the experience at home and abroad, we determine that the 5-km radius area and the achievable places in 15 minutes from the airport are the initial study region, and all the enterprises inside are judged as having the hub-orientation functions and are divided into four categories. Then, inside the concentric circles of different radiuses and the time-based circles, the proportation of enterprises with strong hub-orientation functions is calculated as the evidence of the airport economic area. Finally, we compare the results between concentric circle analysis and time-based analysis, and confirm the scope of airport industrial zone. Researches on the three hub-airports show that Shanghai Hongqiao International Airport has an obvious airport economic area, extending about 2 km from the airport,while Wuxi Shuofang international airport and Nanjing Lukou international airport have no airport economic areas till now. %U https://www.progressingeography.com/EN/10.11820/dlkxjz.2011.10.008
