民航业对国家中心城市集聚辐射效应的影响研究

A Study on the Influence of Civil Aviation Industry on the Agglomeration and Radiation Effect of National Central Cities

基于国家中心城市2003—2019年面板数据,通过构建双向固定效应模型和传导机制模型,重点考察民航业对国家中心城市集聚辐射效应的影响及其作用机理,实证研究发现:民航业对国家中心城市集聚辐射效应具有显著正向影响;大型枢纽机场对城市集聚辐射效应的提升作用更强;国际贸易和产业结构高级化的正向效应是民航业促进国家中心城市集聚辐射效应提升的主要传导途径,且国际贸易处于首要位置。为此,做强以航空运输为核心的综合立体交通体系、促进临空经济与城市经济融合发展、持续深化对外开放战略,有助于国家中心城市实现高质量发展。

Based on the panel data of national central cities from 2003 to 2019, a two-way fixed-effect model and a transmission mechanism model are constructed to investigate the impact and the mechanism of civil aviation industry on the agglomeration and radiation effect of national central cities. The study shows that civil aviation industry has a significant positive impact on the agglomeration and radiation effect of national central cities. Large hub airports have stronger promotion effect on the agglomeration and radiation effect of the cities. The positive effects of international trade and advanced industrial structure are the main transmission paths for the civil aviation industry to promote the agglomeration and radiation effect of national central cities, and international trade plays the leading role. Therefore, strengthening the comprehensive transport network with air transportation as the core, promoting the integrated development of airport economy and urban economy, and continuously deepening the opening-up policies will help national central cities achieve high-quality development.
