本研究主要以賽局理論建構港口國檢查單位與航商對於船舶安全缺失檢查機制，港口國檢查單位策略空間包括船舶「結構安全」、「救生項目」、「消防安全」、「緊急系統」、「推進與輔助系統」、「旅客服務系統」等六項指標進行實質性檢查和形式上檢查，航商的策略選擇是船舶接受安全缺失檢查合格和不合格。當懲罰值等於付出改善設備的成本時，港口國檢查單位最佳檢查策略為針對消防安全進行實質審查及形式審查，且頇針對旅客服務系統進行實質審查，此時航商通過檢查的機率為0.501。反之，當懲罰值低於付出改善設備的成本時，此時航商通過檢查的機率為0.333，顯見當懲罰值低於付出改善設備的成本時，航商通過檢查率偏低。

In this study, the inspection strategies of PSC include structural safety, lifesaving, fire safety, emergency systems, propulsion and auxiliary systems, and passenger service systems. The strategic choice of the shipping companies is to check the qualified and unqualified. The penalty value is equal to the improvement cost, the optimal inspection policy is to conduct a substantive examination of the fire safety and passenger service system, at this time, the probability of the qualified is 0.501. Conversely, the penalty value is lower, the qualified probability is 0.333.
