本文廣泛的討論了西周時期土地的各種現象，初步將當時的土地情形分為取得和轉讓兩個主要部份。在取得方面，指出「王土」的觀念雖然確實存在，但其實際內含是名義遠超過實質。在轉讓方面，除了確定諸侯貴族對土地已掌握所有權，並提出掌握土地所有權的可能途徑即來自於職官組織的強化和累世不變的主從關係的確立。在諸侯貴族已確實掌握土地所有權並以兼併行為擴張土地的情況下，春秋諸侯的霸權與西周末葉的混亂即本於此。 This paper makes a broad discussion about various situations of land distributions during the Western Chou Dynasty. First，two types of land distributions are mainly illustrated : one is acquirement of lands ; the other is transfer of the ownership of lands. In acquirement，it is suggested that the idea of " crown land "（王土） did exist，though，it in fact existed in the name more than in the substance. In transfer of ownership，this paper assures that feudatories and the nobility held the ownership of lands ; in addition，it affirms that possible approaches of obtaining ownership of land have indeed come from the reinforcement of bureaucracy and persistent subjection relations. While feudatories and the nobility actually possessed the ownership of lands and tried to extend their lands through annexation，this was where the hegemony of feudatories during the Spring and Autumon Period and turmoil of the last years of the Western Chou originated in.
