Research On The Influence Of The Construction Of Aviation Dual Hub On The Economic Development Of The Port City

As the world is undergoing changes, the stream of people, logistics, business, information and capital flow constitute the global economy foundation, which will determine the trend of economy. The port city is the center of the five flow, and its competiveness is improved due to its location advantages, advanced economy, and excellent investment environment.

Meanwhile, the prosperity of the port city economy also contributes to the development of aviation hub.As the aviation hub of port cities find it difficult to sustain the growing demand for urban logistics, the construction of aviation dual hub is imperative. Firstly, this paper introduces the connotation of aviation hub, and expounds the construction of aviation hub promoting air logistics industry and the interactive correlation and operation mechanism between aviation logistics and airport economy, proving its competitiveness by means of SWOT analysis. It focuses on the relationship between aviation dual hub and port city. It explains the port city can provide a superior development environment for aviation dual hub with a case. Finally, it selects an aviation dual hub of a coastal city as the representative research object, using the trend analysis, the input-output method and the combination of quantity and quality method to study the influence of the aviation dual hub on the economic development of its city in depth, including the contribution to GDP, the impact of backward linkages and forward linkages.It shows that the construction of air dual hub can solve the problem of insufficiency transport capacity, provide strong support for the economic development, and produce huge economic profits and social benefits.
