A complex and stable system is constituted by airport passenger volume, airport transport corridor and construction investment. In the system, the capacity and congestion level of airport transport corridor would affect airport passenger volume, and construction investment would improve airport transport volume to meet the needs of airport passenger volume growth. From the view of system dynamic, system dynamics mechanism on airport transport corridor was analyzed, a system dynamics model containing airport passenger volume, airport transport corridor capacity and construction investment was established, and then the reasonableness was examined. Two conclusions were obtained through simulation analysis. On the one hand, it is related to the long-term development of the aviation industry whether two parameters, congestion threshold and improvement coefficient on airport transport corridor, should be set reasonably. On the other hand, within the allowable range, moderate advance investment on airport transport corridor can meet the needs of long-term traffic development, and promote the healthy development of the aviation industry.
