Port based transportations are key elements governing the operation of global maritime logistics. In China, the southeast coastline suffers from typhoons frequently every year and causes many disruptions to port operations and thus economic losses. Quantitative evaluation of coastal ports' economic losses induced by typhoons is quite demanding and can serve as guidance for port operation planning and disaster prevention. In this paper, a framework based on a hybrid wind numerical model for assessing the direct and indirect economic losses of coastline caused by typhoon-induced extreme wind is proposed. The estimation of port disruptions and their durations is realized based on the typhoon hybrid wind numerical model. For the direct economic losses, this model considers losses to the port based on the loading/unloading operations of containers. The disruption days and economic losses of 31 ports along China's coastline are selected. These include ports from the Bohai Rim Port Cluster, Yangtze River Delta Port Cluster, Southeastern Coastal Port Cluster, Pearl River Delta Port Cluster, and Southwestern Coastal Port Cluster. The analysis takes the record of typhoons from 2006 to 2020 for this investigation. The influence of time-varying variables on economic losses, such as economic growth rate, has been considered. For the indirect economic losses, the input-output models of 11 different provinces (or municipalities) are employed to analyze each sector. Features of adopting a climate model in the economic evaluations are discussed.
