越南在一千兩百年前曾是一個國際貿易集散地，許多中國、印度和南海諸國的南船往來於越南北部。印度僧侶時常隨同商賈前往中國，途經北越，並在越南短暫停留，中國的僧侶也是如此。因此越南成了印度佛教從南海入中國的轉運站。
本文以唐朝時候的安南與中國為觀察時段，以史料、僧侶、佛經、行紀、詩文和筆記等文獻材料為主，考察安南與唐朝之間的往來的僧侶種類和傳法內容，以了解僧侶傳播佛法的過程和交融影響的佛教思想，並分判越南禪宗的發展樣態。全文分「安南佛教發展的梗概」、「唐朝與安南僧人在海上絲路往來的活動」和「安南與唐朝佛教交互影響的樣態」等三大部分。
結果顯示，南海這條海路為唐朝與安南佛教交流寫下重要的一頁歷史，促成兩地的佛學內涵交融，唐朝僧人得安南僧人的協助學會梵語、崑崙語，能一起譯經、一起到印度求法;安南的佛教因唐朝大乘佛教的影響而以禪宗為主，無言通入安南，為安南開了佛教禪派;唐朝的佛教因安南的小乘禪法而有禪律兼修與兼修密咒的走向;安南僧侶在中國佛經翻譯史上的貢獻應是很大的，而中國僧侶的僧傳、詩文、西域求法紀行一類的文字，更是為這條海上絲路留下許多紀錄。
