本文探讨的东亚文学指由中国、日本、韩国三国文学共同构成的区域文学。在英语世界，东亚文学研究主要体现于文学史书写中的东亚文学整体观和相关作家作品研究两方面。其中，美国学者唐丽园(Karen Laura Thornber)出版的专著与文章的重点论述对象之一就是东亚各国，主要是中国大陆和台湾地区、以及日本、韩国的文学。她的东亚文学研究新意迭出，但也存在问题。她对东亚文学展开的整体论述，进行的比较研究展现了对东亚文学内部联系的个人思考。唐丽园有关东亚文学研究的著作主要有《运动中的文本帝国：日本文学在中国大陆及台湾地区、韩国的文化转换》（Empire of Texts in Motion: Chinese, Korean, and Taiwanese Transculturations of Japanese Literature）与《生态含混：环境危机与东亚文学》（Ecoambiguity： Environmental Crises and East Asian Literatures）。这两部著作是本文论述的核心文本。 本文由五个部分组成。绪论介绍研究唐丽园东亚文学论述的缘起，她的个人经历，阅读视野，实地考察经验与学术路径，突出她研究东亚文学内部互动的开拓性意义与存在的问题；第一章解读唐丽园的首部专著《运动中的文本帝国：日本文学在中国大陆及台湾地区、韩国的文化转换》，概括这本书的主要内容与思路，重点分析她的“文学接触星云”构想，具体论述中国大陆及台湾地区、日本、韩国的语言接触，读者接触，作者接触，文本接触，展现战后东亚的文学接触，在概括整本书的写作逻辑与视野之后分析唐丽园研究的局限之处；第二章探究唐丽园的第二部著作《生态含混：环境危机与东亚文学》，提炼其中的主要论题：环境危机、东亚文学、生态的含混性，以此为基础补充分析第一章唐丽园东亚文学研究的特点；第三章做出总结和反思，概括唐丽园东亚文学研究的特点，展望东亚文学研究的发展前景；最后得出结语，在全球史观和文化多元主义思潮盛行的学术背景下，唐丽园笔下的东亚文学接触现象孕育着从区域文学走向世界文学的希望。

In the English world, the studies of East Asian literatures mainly relate to the holistic view of East Asian literatures revealed in the writing of the history of literature and the studies of the works of East Asian writers. The studies of East Asian literatures by American scholar Karen Laura Thornber is being constructed and worth noting herein. In recent years, one of the focuses of her monographs and articles has been the literatures of East Asian countries, mainly referring to Japan, China and Korea. She has generally discussed East Asian literatures and stressed the internal connections of literatures in this region. This thesis lists Karen Laura Thornber 's monographs on the studies of East Asian literatures, Empire of Texts in Motion: Chinese, Korean, and Taiwanese Transculturations of Japanese Literature and Ecoambiguity: Environmental Crises and East Asian Literatures as research objects. This thesis consists of five parts.

The first chapter focuses on Karen Laura Thornber's first monograph Empire of Texts in Motion: Chinese, Korean, and Taiwanese Transculturations of Japanese Literature. This chapter summarizes the main contents and ideas of Karen Laura Thornber and focuses on the concept “the literary contact nebula” proposed in this book. Then all the linguistic contact, readerly contact, writerly contact and textual contact in China, Japan and Korea is anlayzed respectively, based on which this chapter summarizes the writing logic of the entire book and analyzes the limitations of her study. The second chapter explores the main issues of Karen Laura Thornber's second book, Ecoambiguity: Environmental Crises and East Asian Literatures, that is, environmental crisis, East Asian literatures and ecological ambiguity. This chapter continues to generalize the characteristics of her studies on East Asian literatures analyzed in the first chapter. The third chapter summarizes and reflects the characteristics of Karen Laura Thornber’s studies on East Asian literatures, and attempts to propose the future of studies on East Asian literatures; Finally, based on the academic background of the global trend and cultural pluralism, Karen Laura Thornber’s exposure to East Asian literature contacts engenders the hope that national literature can go beyond regional literature to the world literature.
