中文摘要：

学界对于景颇／克钦先民在古代历史文献当中的记载的研究已经十分丰富，但是到目前为止，尚未有专文对此进行系统梳理和评述，尤其是对于其民族源流的认识，出现了超出历史认知的新的论述，且已产生一定范围和程度的影响。对此，应做如何看待？对于景颇／克钦如此一族跨三国的族群而言，无疑是其历史研究中一个不可回避的问题。因此，本文拟就达成上述目的进行分析论述。

英文摘要：

The records and researches of ancient Jingpo/Kachin people are quite abundant in ancient historical documents. But up to now, there is no systematic carding and reviewing on this topic in any article. The cognition of its ethnic origins has shed new light on the historical recognition, and it has already exerted a certain extent of impact. How should we regard this issue？ With re- gard to Jingpo/Kachin - people - one ethnic group distributed in three countries, it is an unavoidable question. Therefore, some advice and ideas will be put forward in this paper. Any correction of the improper ideas of this paper will be appreciated.
