Identity plays an important role in second language acquisition, and positive identity promotes the improvement of second language proficiency. This study examines the effects of three types of identity(ethnic identity, cultural identity and language identity) on the complexity, accuracy and fluency of spoken Chinese of L2 learners from Korea, Russia and Pakistan. The results show that:(1) Identity has a significant impact on the L2 spoken Chinese, and the effects of different types of identify are not the same: ethnic identity and language identity have significant effects on oral production, while cultural identity has little effect on oral production.(2) Learners’ mother tongue has different effects on L2 oral Chinese production: ethnic identity has a greater impact on Korean native speakers, language identity greater on Russian native speakers, while ethnic identity and language identity have a relatively small impact on Pakistanian native speakers.
