Abstract: This article investigates the conflictive construction of identities in Chinese interactions. We examine the way in which people build up their own identities as “experts” and negate others’ similar identities in Chinese televised debates with complex participation structure. Our datasets are collected from 120 Chinese televised debates. Using indexicality (Bucholtz, Mary & Kira Hall. 2005. Identity and interaction: a socio-cultural linguistic approach. Discourse Studies 7[4/5]. 585–614) and Membership Categorization (Sacks, Harvey. 1992. Lectures on conversation, vols I and II, edited by G. Jefferson. Oxford: Blackwell) as analytic notions to capture the interactional co-construction of identities, we examine the ways in which identity co-construction in such conflict scenarios takes place, as interactants attempt to construct their own identities as experts, and negate the expert identities of others. This exploration fills an important knowledge gap: little research has been done on Chinese conflict talk, in particular from the perspective of the co-construction of identities. Our research models identity construction in conflict by identifying various routes or “strategies” through which identities can be worked out in conflict scenarios. Our focus is on revealing how interlocutors construct or promote their identity by making their membership category conform to their category-bound activity/attribute, and negate others’ identity by revealing others’ violation of category-bound activity/attribute.
