Abstract

The purposes of this paper were: 1) to identify the structural changes of the northeast Asia airport network caused by the pandemic of COVID-19 using social network analysis (SNA) and 2) to suggest proposals for improving airport competitiveness. In this respect, the entire international air routes in northeast Asia airport collected data of 4-10 March 2019 and 9-15 March 2020 through schedules analyzer database of OAG. We found that both the density and centrality have decreased since the spread of COVID-19. The government and airport authorities need active support such as a reduction of various fees and a moratorium on transportation rights to overcome the crisis in the air transport industry. When the COVID-19 situation calms down in the future, we hope that further research will be conducted to identify the structural changes in the SNA aspects through the vast data establishment in countries such as the EU and America.

본 연구는 코로나19의 세계적 대유행(Pandemic)으로 인한 동북아시아 공항 네트워크의 구조적 변화를 분석하고 공항 경쟁력 향상에 도움을 줄 수 있는 정책 제언을 도출하고자 하였다. 이를 위해 소셜 네트워크 분석(Social Network Analysis; SNA)을 이용하여 코로나19 전후 네트워크의 중심성 분석을 시행하고 네트워크를 시각화하였다. 이를 위해 2019년 3월 4~10일 및 2020년 3월 9~15일 각 일주일간의 동북아시아 공항 국제선 전체를 대상으로 출발·도착하는 노선을 OAG(Official Airline Guide)의 Schedules Analyzer Database를 통해 추출하였다. 분석 결과 코로나19 사태 이후 동북아 공항 네트워크의 노드와 링크, 밀도가 감소한 것으로 나타났다. 전반적인 네트워크 밀도 감소 속에서도 인천공항의 중심성은 상대적으로 덜 감소한 것으로 확인되었다. 수요 급감을 겪고 있는 항공운송산업의 위기 극복을 위해 정부 및 공항의 적극적 지원이 필요할 것이다. 본 연구 결과는 코로나19 확산이 동북아시아 공항 네트워크의 중심성 지수에 미친 영향을 분석하여 향후 수요 회복 시 전략 수립에 필요한 실무적 시사점을 제시하였다는 점에서 의의를 갖는다.
