Recent sociolinguistic studies have given increased attention to the situated practice of members of locally based communities. Linguistic variation examined tends to fall on a continuum between a territorially based “standard” variety and a regional or ethnic vernacular. This article emphasizes the need for sociolinguistics, especially variationist sociolinguistics, to look beyond strictly local contexts and to go beyond treating variation as located along a linear dimension of standard and vernacular. Based on quantitative analysis of four phonological variables among Chinese professionals in foreign and state-owned companies in Beijing, this study demonstrates that professionals in foreign businesses employ linguistic resources from both local and global sources to construct a new cosmopolitan variety of Mandarin, whereas their counterparts in state-owned businesses favor the use of local features. The study shows that variation does not just reflect existing social categories and social change, but is a resource for constructing those categories and participates in social change.
