本文借助热奈特的经典叙事学相关理论，分析并建构《小径分岔的花园》的叙事结构——多层嵌套无限分岔的迷宫。首先探讨了叙述者与受述者之间的关系以及叙述层次的精心构建，这体现了叙事结构的多层嵌套。之后分析了叙事时间和迷宫叙事的特点，这体现了叙事结构的无限分岔。叙事结构促进了人的自我认同等叙述母题的表达，而叙述母题反过来丰富了叙事结构的意义。最后从博尔赫斯的时间哲学角度分析了叙事结构的成因。这些共同造就了《小径分岔的的花园》多层嵌套无限分岔的迷宫式叙事结构。

With the help of Genette's classical narrative theory, this paper analyzes and constructs the narrative structure of 《The Garden of Forking Paths》—— multi-layer embedded maze with infinite bifurcation. First, it discusses the relationship between the narrator and the recipient and the careful construction of the narrative level, which reflects the multi-layer nesting of the maze narrative. Later, the characteristics of narrative time and maze narrative structure are analyzed, which reflects the infinite bifurcation of maze narrative.The narrative structure promotes the expression of narrative motifs such as self-identity, thus enriching the meaning of the narrative structure. Finally, the causes of the narrative structure are analyzed from the time philosophy of Borges. Together, these make 《The Garden of Forking Paths》a labyrinth narrative structure with infinite bifurcations.
