Since the establishment of business English in China, the research trend on business English stylistics is developing into a multi-perspective, at multi-levels and with multi-approaches. However, the research orientation and definition of business English stylistics are still controversial. This paper attempts to clarify the research orientation and definition of business English stylistics, construct a theoretical framework for business English stylistics, and explore a set of research paradigms of business English stylistics that can cover different business English genres, and also provide a referable example for the specific analysis of stylistic features and functional significance of business English.
