Abstract: Maritime chokepoints are crucial nodes in international supply chains, facilitating most of the global freight transport and the distribution of industrial raw materials and goods. However, these chokepoints are vulnerable to disruptions from severe weather, traffic accidents, and unpredictable factors, significantly impacting global maritime networks. Therefore, it is crucial to understand the role of chokepoints to improve the robustness of the global maritime network. This paper aims to assess the influence of a crucial maritime chokepoint, with a specific focus on the Taiwan Strait, and its effects on the global maritime network. Specifically, five maritime networks with different scales are constructed based on massive global Automatic Identification System (AIS) data. The Taiwan Strait is selected as an important maritime chokepoint in the multi-scale networks. Then, the dependence of the Taiwan Strait on various ports and economies is analyzed by nine selected evaluation metrics. Finally, this study thoroughly analyzes the impact of the Taiwan Strait for multiscale maritime networks extracted from AIS. The Taiwan Strait has been subdivided and analyzed to reveal the important areas of maritime traffic flow within the Taiwan Strait. The global maritime traffic flow analytical results demonstrate the huge influence of the Taiwan Strait on Chinese ports and Asian economies.
