This paper explores the relationship between Taiwan's Hakka television channel and the ethnic identity construction of the metropolitan Hakka audience and examines the role Hakka Television plays in the formation of Hakka identity. In-depth interviews with sixteen Taipei Hakka viewers showed that Hakka TV has increased the sense of ethnic identity of metropolitan Hakka in four aspects: self-identification, sense of belonging, ethnic attitude, and ethnic involvement. The golden triangle for Hakka identity formation consists of primordial attachment, interpersonal interaction with significant others and Hakka TV. The role of Hakka TV in constructing a Hakka identity for the metropolitan Taipei Hakka audience lies in the expansion of the sense of belonging and identity of Hakka viewers from the primordial ties within Hakka families to the whole Hakka ethnic group. Moreover, many metropolitan Hakka viewers, who tend to hide their Hakka identity, have become more involved in Hakka cultural activities because of Hakka TV, indicating that they have more self-confidence and a sense of pride in being Hakka.
