20世纪80年代以来，中国文学从创作到接受的所有层面都受到市场经济和城市繁荣的冲击。因此，继承了传统启蒙先驱创建的婚外恋小说，也必须在新文化背景下，积极探索自身的改进与创新。从如此丰富的肌理着手，才能够对20世纪80年代以来的婚外恋叙事进行多角度的探究，才能够归纳出该时期婚外恋叙事中不断变换着的手法中存在的固定框架。相对于以前的婚外恋叙事，本文试图展现20世纪80年代以来婚外恋叙事的新变。本文的具体结构如下：引言中论述了婚外恋题材小说的发展概况和叙事背景，为下文的婚外恋小说叙事研究奠定基础；第一章中，归类出婚外恋小说叙事中主要存在的五种故事类型，即精神慰藉型、感官享乐型、金钱权力型、婚姻倦怠型、伦理冲击型；第二章中，总结了“柔化”的丈夫形象和多元的妻子形象，同时，从新的研究视角分析了情人形象以及读者对情人形象的认知变化；第三章中，从“看似不同”的婚外恋叙事中，概括出“常存”的结构形态——层递式结构、对称性结构、复调式结构；第四章则分析了作家们在婚外恋故事中形成的叙事策略，表现为后现代性的传奇叙事、去中心化的个人叙事、书写欲望的货币叙事。研究发现，文化传统的巨大力量、人性内部的矛盾冲突以及当代消费文化的现实语境是影响20世纪80年代以来婚外恋题材小说创作模式化的重要原因。因此，如何走近现实以及如何升华现实，突破现有叙事类型、维持其独特的审美个性仍是它创作的最大困境之一。所以，我们要警惕现实文化语境对文学审美独立性的隐形控制，要建立起以文学为中心的生产模式。从精神和思想上来说，必须呼吁未来的文学创作大力彰显文学叙事的原创性与独创性。

Involving the creation to accepting, great prosperity of market economy and rapid promotion of urban process deeply influenced all Chinese literature since 1980’s. Therefore，in the new cultural context, novels about extramarital affairs not only inherit the tradition but also actively explore the improvement and innovation of their own. It is such a rich texture that we can explore the narrative of extramarital affairs since 1980’s with multiple angle. Also, fixed framework exists in transforming methods of writing can be summed up in this period’s narration of extramarital affairs. Compared to the previous narrative of extramarital affairs，this paper attempts to describe the new changes in the narrative of extramarital affair since 1980’s. The detailed structure is as follows: the introduction presents the general situation of development and the narrative background which exist in novels about extramarital affairs，and they lay the foundation for the narrative research of extramarital affairs. The first chapter classifies five story modes，which include spiritual comfort，sensual pleasure，power and money，marriage burnout and ethical impact; the second chapter summarizes the image feature of husbands，wives and lovers，as well as the readers’ cognitive changes on Valentine’s image. From “ seemingly different ” narrative of extramarital affairs, the third chapter generalized the “remain” structure: layer recursive structure，symmetry structure and polyphonic structure. At last，the fourth chapter analyzes the narrative strategies，such as the legendary narrative of Post Modernity，the personal narrative which is away from “ the center ” and the monetary narrative for writing desire，which are often used by writers in novels about extramarital affairs. It is easy to find that the conflict between the internal traditional culture and human nature and the real context of contemporary consumer culture are important factors，which lead to the creation mode of novels about extramarital affairs. So, one of the biggest difficulties in the creation is how to approach and sublimate the reality，how to break through the existing type and maintain its unique aesthetic personality. Therefore，in the future literary journey，we need to be wary of consumption culture，which may invisibly control the independence in literary aesthetic. At the same time，we must establish a literature production pattern，which is different from the consumption mechanism，advocating the originality and originality of literary narration in the spirit and thought.
