Review of Research on Development of Speech Act Theory and Its Application

Speech Act Theory has been the focus of linguistic research since its introduction in the early 1960s. This paper reviews the literature on Speech Act Theory collected from core journals at home and abroad and finds that the theory has been constantly revised and supplemented by domestic and international academics in the process of development; it also finds that Speech Act Theory has been well developed and applied in literature, journalism and communication, education and other fields in recent years, but not much research has been conducted in the field of political speech act. The former focuses on speech strategies, while the latter focuses on individual style differences. By reviewing the development of Speech Act Theory at home and abroad, we can help understand its development prospects and provide a theoretical framework for political speech act research; by reviewing applied research in different fields, we can better understand the application value of Speech Act Theory and provide inspiration on research methods for future political speech act research.
