商务英语学科定位的学理依据

Study on the disciplinary theoretical system construction of business English

目前商务英语学科理论体系得到的关注相对较少,导致了其学科定位差异。商务英语学科定位的学理依据既要解释商务英语学科的理论渊源,确定商务英语知识体系在人类知识谱系中的位置,也要提出学科的理论框架。本文溯源了语言学与经济学理论的交叉点,阐明了商务英语学科的理论渊源,同时提出了三个基本命题作为商务英语学科的学理依据。三个命题统一于"理性选择"理论,具有理论的一致性。文章还初步描述了学科边界、方法论等商务英语学科的基本理论框架。

The disciplinary theoretical system of business English has received relatively less attention, which results in different discipline orientations. To construct the disciplinary theoretical system of business English, it is logical to resort to classical economics and modern linguistics since they both deal with, from respective perspectives, the eco-nomic attributes of language. This paper, based on a systematic elaboration of the economic attributes of language, makes an attempt to propose three propositions as the basis for the disciplinary theoretical system of business English. The three propositions are unified in ＂rational choice＂ in economics and achieve theoretical consistency. The paper also discusses the disciplinary boundaries and methodology of business English.
