論文摘要： 汽車為現代人不可或缺之交通工具，汽車責任保險關乎社會大眾權益甚巨，不僅僅是保險人與被保險人兩者之間保險契約之關係，尚且關乎汽車意外事故受害第三人之權利，而每個人都有可能成為汽車意外事故之受害第三人。故保障受害第三人之權益即是保障多數人之權益。為使受害第三人之權益能獲得充分周全之保障，於汽車責任保險之中，創立受害第三人直接請求權制度，實不失為一良法。然而於我國無論是強制汽車責任保險受害第三人直接請求權制度抑或是任意汽車責任保險受害第三人直接請求權制度，均存有若干疑義及缺失，因而引發筆者研究動機。本文之研究方法為(1)、比較法研究及(2)、邏輯架構分析法。將全文分成七章予以論述，主要之研究內容為，以責任保險之意義、思潮及功能為開端，進而論述責任被保險人之保險給付請求權及受害第三人之直接請求權並闡述責任被保險人、責任保險人與受害第三人三者彼此之關係及保險給付請求權與直接請求權競合之處理，並進一步檢視我國現行關於受害第三人直接請求權法令規範之缺失，參酌外國立法例及學說，提出改進建議，期能使我國之受害第三人直接請求權制度，邏輯趨於圓滿一致，以杜絕適用疑義，廣增大眾福祉。 / Abstract： An automobile has become a necessary transportation vehicle for modern people.
