AJCEP 체결국 간의 항만 네트워크 변화에 관한 연구

Agreements for trade liberalization, including free trade agreements, which have been actively signed around the world since the 1990s, have a good impact on each country's production, trade, and logistics activities. Each country concludes agreements for various purposes, and in order to achieve the objectives set by each country at the time of signing the agreement, it is a prerequisite to expand each country's trade activities and to transport goods efficiently without impairing the transport efficiency of goods even if the means of trade activities change. In this study, we examined how the port network structure changed before and after the signing of the agreement for major ports between AJCEP signatories. The analysis results of this study are summarized as follows. Before the conclusion of AJCEP (2004) and after the conclusion of AJCEP (2013), Singapore Port ranked first in all items of connection degree centrality, proximity centrality, and mediation centrality. At the time of the conclusion of AJCEP (2022), the ranking was lowered except for inflow centrality, and it was confirmed that the level of centrality was balanced between Japan and ASEAN countries. In addition, in terms of spill centrality, it was possible to confirm the growth of Japanese ports.
