Abstract: According to social linguistics, the transformation of a dialect is mainly restricted by social conditions such as population migration, the division of administrative regions and geographical environment on the one hand and by psychological factors such as language attitude and language emotion on the other. The investigation of the pronunciation transformation of Huaxi dialect in Guiyang shows that other elements, together with the above-mentioned factors, play an important role. The popularity of the mass media, which mainly uses mandarin, and the popularization of education in schools, which takes mandarin as the campus language, are more important social elements. In the process of urbanization, people’s language expectation deriving from their life expectation is an important psychological element in the pronunciation transformation of a dialect.
