A new subway, line 9 linking Western and Eastern Seoul began its services for citizens between Gimpo airport and Gangnam area within 30 minutes by express transit service. Seoul Metro Line 9 Corporation plans to operate both local transit service which will stop at every station, and express transit service that will stop at several key stations including junctions. The passengers on line 9 will be able to transfer to lines 2, 3, 5, 8, Bundang and Incheon International Airport. The Line 9 is expected to disperse the demand for line 2, having the most number of subway users, and will provide passengers with less crowded travel. The new line will also help residents in southern Seoul outskirts and Gyeonggi provincial cities including Bundang vicinity, and Gangdong area commuters get better access to Gimpo and incheon Airports. The Corporation expects to transfer 560,000 passengers daily by the subway line 9. Seoul Development Institute conducted network reshuffle study for Seoul Metro system to sort out congestion problem due to its irrational line alignments and inconvenient transfer. Among several candidate plans of network reshuffling, the direct connection of line 9 with line 5 was chosen as a pilot study. The study found that direct connection of the 2 lines is essential for enhancing transit utility and reducing automobile commuters.

1983년에 중국 정부가 자국민의 해외 여행을 허가한 이래, 중국의 아웃바운드 해외 관광 시장은 비약적으로 발전하였다. 대한민국은 이러한 현상의 최대 수혜 국가 중 하나가 되었으며, 항공운송 분야에 있어 특히 혜택을 보았다. 현재 인천국제공항의 전체 이용객 중 23.9%가 중국인이며, 추후에도 중국여객들이 인천국제공항의 주요한 고객으로 남을 것으로 전망된다. 중국의 광활한 영토와 13억이 넘는 인구를 고려할 때, 중국을 하나의 시장으로만 보는 것이 아니라 여러 지역들이 모인 집합체로 바라볼 필요성이 제기된다. 이렇게 할 시, 각 지역마다 다른 중국여객들이 공항 이용에 있어 보이는 태도와 행동양상의 차이점을 파악하여, 차별화된 서비스 제공의 밑바탕이 될 수 있다. 이를 통하여 중국여객들의 인천국제공항 이용 시 고객 가치와 만족도의 향상에 기여할 수 있다. 본 연구는 중국 정부가 경제, 사회 등의 요소를 고려하여 공인한 방식대로 중국 전체를 다섯 개의 권역으로 분할하여 중국여객들이 인천국제공항 이용에 있어 느끼는 만족도를 조사하고자 한다. 특별히 면세점 이용과 관련된 만족도에 중점을 두고자 한다. 권역별로 지니는 차이점을 분석하여, 권역별로 상이한 서비스 전략을 추진하기 위한 전략적 방향성을 제시한다.

The positive and negative opinion to cargo demand of Incheon's SAMT in the near future remains cloudy. Considering port and shipping environmental changes and the logistics situation of China which explains the lack of facilities in Chinese airports, the creating of SAMT cargoes of the Incheon region could catches a favorable opportunity to be a logistics hub in the North-East Asia. On the other hand, as open-sky policy and direct-call service has been carried out between China and N.A.(North America), Incheon could cause a loss of competitiveness in SAMT because the enhancement in the aspect of the connectivity of Chinese airlines and shipping lines makes customer sent to last destination their cargoes whenever they want. In the same context, this paper analyses on conditions of domestic and international SAMT and proposes in this uncertainty future forecasting of SAMT of Incheon by scenario planning according to changes in integrated SAMT, measuring the likelihood of final scenario. This study shows the Sea & Air multi-transport volume will have either slight increase or decrease from the current condition. Consequently, RFS expansion and system & service improvement through strong ties with major cities in China will be required in a short run aspect. Nonetheless, we also need to take domestic & international transportation environment into account in the long run.
