个体化是系统功能语言学进入21世纪后新发展起来的一个理论模型,主要研究编码取向,其资源分配与亲和关系层级理论为身份建构提供新的研究视角。资源分配从个体发生维度关注社会符号资源的汇流、辨识准则的形成和社会身份的建立。亲和关系则从话语发生和示例化维度强调个体或群组如何调动社会符号资源与其他成员形成绑定联盟或人际区分,进而实现身份协商建构。这一新的理论范式将有助于揭示语篇中所蕴含的个体因素和意识形态,推动身份建构研究朝着人本主义方向发展。本文对身份建构个体化研究的产生背景、涉猎内容、重要理论和研究方法予以回顾,同时对该领域的发展前景予以展望。 Individualization is a new theoretical model developed after the system functional linguistics into the 21st century. It mainly studies coding orientation, and its resource allocation and affinity hierarchy theory provide a new perspective for identity construction. Resource allocation focuses on the confluence of social symbolic resources from the individual occurrence dimension, the formation of identification criteria and the establishment of social identities. Affinity and discourse from the occurrence and demonstration of the dimension of emphasis on how individuals or groups mobilize social symbol resources and other members of the formation of binding alliances or interpersonal differences in order to achieve identity negotiation construction. This new theoretical paradigm will help to reveal the individual elements and ideologies inherent in the discourse and promote the study of identity construction towards humanism. This paper reviews the background, contents, theories and research methods of individual construction of identity construction, and looks forward to the development of this field.
