本文針對西周六自與八自的內部問題作一探究，主要可分為下列五個部份：一、名稱定義，二、組成結構，三、指揮權問題，四、與「△自」的關係，五、八自的移防。具體結論有下列五點：一、西六自與殷八自是結合地域及族類兩種條件而命名，至於殷八自、成周八自只是在「隨地易名」情況下的不同稱法，實際上兩者為一。二、殷八自的指揮系統可分為四個層級：第一層級是由周天子派遣的重臣、諸侯擔任，第二層級是由這些重臣、諸侯的下屬擔任，第三及第四層級則是殷八自的師氏及殷人所組成。三、六自、八自的指揮權由周天子掌握，並由周天子派遣重臣出任總指揮官。四、六自、八自實際上是由西周金文中常見的「△自」所組成，六自實際是六個「自」、八自實際是「3」所組成的軍團。五、從周厲王之後，原本駐守殷地的殷八自移防至成周地區：故因而易名為成周八自，並自此常駐於成周而未再回駐殷地，其目的在於抵禦南方淮夷等外族的侵犯。

This paper will investigate the internal problems of Liu-Shi（六自） and Ba-Shi（八自） of Xi Zhou（西周）. It is divided into five parts: 1. denomination and definition; 2. components and structure; 3. the problem of the right to command; 4. the relationships between -Liu-Shi and Ba-Shi as well as "△ Shi"; 5. the shift for garrison duty of Ba-Shi. The conclusion will be brought out in five points: 1. Xi-Liu-Shi （西六自） and Yin-Ba-Shi （殷八自） are different denomination based on the combination of regions and clans. As fbr Yin-Ba-Shi and Cheng-Zhou-Ba-Shi, they are distinct names according to the context of “the change of names in reliance of locations,” while the fact is that they differ in names but not in kind. 2. The chain of command of Yin-Ba-Shi consists of four hierarchies: the first includes major courtiers and vassals dispatched by the Zhou Emperor; the second the subordinates of these major courtiers and vassals; the third and the fourth the Shi-shi（師氏） and the Yin people of Yin-Ba-Shi. 3. The Zhou Emperor holds the right to command Liu-Shi and Ba-Shi and also the right to designate those among the major courtiers to serve as general commanders. 4. Liu-Shi and Ba-Shi are actually formed by those who are often seen in Xi-Zhou-Jin-Wen, "△ Shi”： Liu-Shi means six Shis while Ba-Shi signifies the army group formed by "Shi." 5. Since Zhou, Li Emperor, the Yin-Ba-Shi originally stationed in Yin shifted to the Cheng-Zhou（成周） area, hence the term Cheng-Zhou-Ba-Shi（成周八自） afterwards. Cheng-Zhou-Ba-Shi never returned to Yin for the rest of their lives. They were responsible for defending against the invasion of foreign tribes such as Huai and Yi in the South.
