在我国56个民族中,有一半以上是跨国民族,主要分布在祖国的西北和西南地区。由于跨国民族是一个特殊的族体,近年来该族体被某种势力集团利用的现象凸显,是导致国家不稳定的一个重要因素。时值构建和谐社会之际,正确处理我国西北和西南地区的跨国民族关系和问题,无疑成为当前研究的重要课题之一,同时也是构建和谐社会的关键所在。 Among the 56 ethnic groups in our country, more than half are multinational nationalities and are mainly distributed in the northwest and southwest regions of the motherland. As transnational ethnic groups are a special kind of ethnic group, the phenomenon of the ethnic group being exploited by some kinds of forces in recent years has become prominent and is an important factor leading to instability in the country. On the occasion of building a harmonious society, correctly handling transnational ethnic relations and problems in the northwestern and southwestern regions of our country undoubtedly has become one of the important topics in current research and is also the key to building a harmonious society.
