本文通过对云南通海蒙古族研究的梳理,讨论相关理论问题,指出对于民族认同来说,重要的是边界的差异和形式的差异,而不是要素的差异和内容的差异。研究者也要注意历史、国家权力等因素对于云南通海蒙古族认同的重要影响,更多关注民族认同的维系及其重新建构的过程。 This paper discusses the Mongolian ethnic studies in Tonghai, Yunnan, and discusses the related theoretical issues. It points out that for the ethnic identity, what is important is the boundary difference and the form difference, not the difference between the elements and the content. Researchers should also pay attention to the important influence of history, state power and other factors on Mongolian identity in Tonghai, Yunnan, and pay more attention to the maintenance of national identity and the process of its re-construction.
