Abstract

Ports play a crucial role in the complex global supply chain. While many researchers have used social network analysis (SNA) to study active networks, there is a lack of SNA cohesion analysis specifically related to logistics and trade. Therefore, this study aims to identify time-series structural changes in all domestic import and export logistics networks, including regions, ports, and airports, by utilizing techniques such as k-core and community analysis. To carry out this analysis, we rely on data from the Korea Customs Service's Import and Export Logistics Statistical Yearbook spanning from 2004 to 2022. The findings from the k-core and community analysis indicate that the cohesion of the domestic import and export logistics network has continuously strengthened over time. Moreover, it reveals that regions, ports, and airports are becoming more cohesive and homogeneous, with Busan Port emerging as the central hub of a large community. These insights are expected to enhance our understanding of global logistics dynamics and contribute to the development of policies and sustainable import and export logistics processes.

글로벌 공급사슬망 내 항만은 서로 복합한 물류 네트워크시스템을 형성하고 있다. 많은 연구자들은 SNA분석을 활용하여 물류 네트워크, 무역 네트워크, 그리고 해상 네트워크 등 활발한 네트워크 관련 연구를 진행해 왔다. 그러나, 기존의 SNA분석에 비해 물류 및 무역과 관련된 SNA 응집성 분석은 미비한 편이다. 따라서, 본 연구는 SNA 응집성 분석기법 중 핵심집단 분석과 커뮤니티 분석을 활용하여 지역, 항만, 공항을 포함한 모든 국내 수출입 물류 네트워크의 시계열적인 구조변화 양상에 대해 파악하고자 한다. 이를 위해 본 연구에서는 2004년부터 2022년까지의 관세청 수출입물류통계연보 자료를 활용하였다. 본 연구의 결과는 다음과 같다. 핵심집단과 커뮤니티 분석 결과, 국내 수출입 물류 네트워크 응집성은 지속적으로 강화되고 있었으며 지역, 항만, 공항의 결속구조가 높아지고 동질적 형태가 증가하고 있음을 확인하였다. 또한, 부산항이 주요 커뮤니티의 중심인 것을 확인하였다. 이를 통해 글로벌 물류환경의 과정을 이해하고, 물류 및 무역 관련 정책과 지속 가능한 수출입 물류 프로세스를 구축하는데 도움이 될 것으로 기대된다.
