고속철도가 공항성과에 미치는 영향: KTX를 중심으로

Abstract

Purpose – Despite of the close relationship between high-speed railway and airplane, there is a lack of research on the impact of high-speed railways on the performance of regional airports. Thus, the purpose of this study is to identify the effect of high-speed railway on the airport performance in Korea. Design, data, and methodology – The data were gathered from the statistics from the Korea Airports Corporation and the Ministry of Land, Infrastructure and Transport from 2013 to 2019. The variables used in the study were the total number of annual passenger and the total number of flight operation as dependent variables, as well as the total number of annual KTX passengers and the distance between the airport and the closest KTX station as independent variables. This study adopted both the random and the fixed effect models for the panel data. The statistical software ‘Stata’ was used for the empirical analysis. Result – The results showed that the number of KTX passengers had a positive effect on the airport’s passenger and flight operation performance. However, the distance between the KTX station and each airport had a negative effect on the airport’s passenger performance. Conclusions –The results revealed that the closer the distance between the high-speed railway station and the airport is, the higher the airport’s performance. In addition, the airport’s performance also would be increased by the increase of the number of high-speed railway passengers. In conclusion, there is existed the characteristics of the complementary relationship between the airport and the high-speed railway for current in Korea.
