Abstract:Public sign is a special type of writing, targeting at foreigners. So the Chinese-English translation of public signs is bound to be closely related to language and culture，and intertextuality theory precisely meets such a demand, for translation itself is a kind of intertextuality activity. Based on the above considerations，the author would like to tentatively explore the translation of public signs from the perspective of intertextuality．After a detailed discussion and exploration of the relation between intertextuality and C-E translation of public signs, the author of this thesis goes on to undertake a case study of C-E translation of public signs in Guangzhou City. Through the study, the author concludes that intertextuality theory plays a directive role in both theoretical study and practice of C-E translation of public signs. The author expects that the research results and suggestions of this thesis will help improve the quality of C-E translation of public signs and benefit the favorable image of Guangzhou City as an international metropolis.

摘要:公示语属于一种特殊文体，它的阅读对象是外国人。正因如此，公示语的汉英翻译必然与语言和文化息息相关，而互文性理论正好满足了这一需求，因为翻译本身就是一种互文性活动。基于以上考虑，作者尝试着运用互文性理论探索公示语的汉英翻译。在详细地探讨互文性理论和公示语汉英翻译之间的关系之后，作者以广州市为对象对公示语汉英翻译进行案例研究。作者进而得出结论：互文性理论在公示语汉英翻译的理论与实践中起着重要的指导作用。作者希望本文的研究结果和建议有助于提高公示语汉英翻译的质量，并有助于提升广州作为国际大都市的形象。
