While ethnic groups identity and national identity appear weakly negative relationship. Secondly, double identities, Mongolian Chinesization tendency, Mongolian Nationalism tendency and marginalization are four relationship types of Mongolian teenagers,they present “multiple- inverted pyramid" structure. Thirdly,the model of the ethnic groups identity and national identity of Mongolian teenagers is “external intergration 一intenlal conservativeâ€in micro aspects. Mongolian Chinesizaition on behavior and cognition does not affect teenagers identifying with his ethnic groups emotionally. Lastly, the result of the influence factors analysis verify the theory of constructivism. The type of group structure can affect the formation, keep and change of individual’s identity.
