초록

본 연구는 인천공항의 비항공수익 비중이 과연 지나치게 높은 것인가라는 연구 질문에서 출발하게 되었다. 공항의 전통적 비즈니스 모델에 기반 한 항공수익은 여러 규제로 인해 성장의 한계를 가지고 있지만, 경쟁력 향상을 고민하는 공항운영주체들에 의해 비항공수익 증대에 대한 관심이 커지고 있다. 본 연구에서는 공항의 비항공수익이 공항사용료에 미치는 영향을 다루고 있으며, 공항산업의 핵심이슈 중 하나인 민영화 요인을 연구에 반영하였다. 또한, 인천공항 단일 사례가 아닌 전 세계 178개 공항을 대상으로 실증 분석하였다. 연구결과 국제공항의 비항공수익 비중이 높을수록 공항사용료는 낮아지는 것으로 나타났으며, 민간지분율은 비항공수익 비중과 공항사용료 간의 인과관계를 양(+)의 방향으로 조절하였다. 이는 공항의 민영화 추진이 상업 활동 증대를 통한 공항사용료 감소효과를 상쇄하는 결과를 초래할 수 있는 것으로 해석할 수 있다. 조절효과에 대한 가설검증은 그림으로 이해하기 쉽도록 도표로 제시하였다.

This study started with the question of whether the percentage of non-aeronautical revenues at Incheon airport was extremely high when compared with other international airports. Although aeronautical revenues for the airport based on the traditional business model have the limits to grow due to various regulations, stakeholders concerned about improving the competitiveness recently have been interested in increasing non-aeronautical revenues. This study deals with the effect of non-aeronautical revenues at international airports on airport charges as the extent of airport privatization get stronger. To examine hypotheses, we collected international data from trustful sources. Finally, we conducted an empirical analysis of 178 airports worldwide. As a result, the higher the percentage of non-aeronautical revenues at international airports, the lower the airport charges were. Besides, the private equity ratio positively moderated the relationship between the percentage of non-aeronautical revenues and airport charges. Privatization of airports may offset the effects of reduced airport charges through increased commercial activity. Graphical display for moderation effect is offered to facilitate comprehension.
