Yangpu Port and Haikou Port, as important components of the Hainan Free Trade Port, play a critical role in the regional economic development through their port layout and shipping network. This paper systematically analyzes and studies the shipping accessibility between Yangpu Port and Haikou Port, focusing on the ports' geographical locations, port conditions, spatial distribution patterns, and the factors influencing shipping accessibility. The study reveals the characteristics of Hainan's port layout and the current state of its shipping network. In the context of the construction of the Hainan Free Trade Port, researching the shipping accessibility between Yangpu Port and Haikou Port is crucial for promoting the high-quality development of the free trade port. This research is beneficial for optimizing port layout, enhancing port competitiveness, and accelerating the upgrading of international shipping hub construction. In the future, as the policies of the Hainan Free Trade Port are further implemented and economic and social development continues, the findings of this study will provide important reference and support for the sustainable development of ports in Hainan Province.
