中文摘要：

拉铁摩尔在对中国边疆的研究中过于强调北方边疆，而忽略南部边疆，强调地理和经济因素对中国核心区域的范围的界定，而未能认识到南部边缘地带与核心区域互动的复杂性，以及这些互动在形塑华夏过程中的作用。王铭铭在“藏彝走廊”研究的基础上提出中间圈的概念，这一概念涵盖了拉铁摩尔提出的内陆边疆地区，也包括了西南的藏彝走廊和东南的部分少数族群。在考虑中国的南部边疆问题时，从核心圈、中间圈和外圈三个圈层的互动角度来解读这种时代变化，对中国人类学和历史学的研究是非常有意义的。

英文摘要：

Lattimore places too much emphasis on northern frontier and ignore the southern partwhen studying Chinese frontier, believing that geographical and economical factors influence thedemarcation of the core region of China. He is not aware of the complexity of the relation betweensouthern border and core region, as well as its role in the process of Chinese evolution. Wang Mingming,in view of the study on ＂Tibetan-Yi Corridor,＂ puts forward the concept of the intermediaries. Theconcept covers Lattimore＇s inner Asian region, and includes southwestern Tibetan-Yi Corridor and parts ofminority ethnic groups in southeast. Considering Chinese southern frontier problems, it is significant tointerpret the changing times from the perspective of interaction among the inner core, the intermediariesand the outer layer, which is meaningful to the study of Chinese anthropology and history.
