在西欧封建社会形成的时期,自然经济占着统治地位,而庄园组织便是这种经济的主要形式。庄园的一切经济活动主要是为着满足封建领主生活上的需要。庄园所生产的农产品及手工制品除很少例外外,都是消耗在庄园之内。那个时候,即使王室的经费,也是依靠领地内庄园的收入,国库就设在庄园之内。为便于供应起见,王室常从一个庄园移到另一个庄园,就地消耗其仓库内的储藏。这一点可说明为什么查理大帝在很长时期没有固定的首都,也可说明为什么他不厌烦琐地规定并参与王室大庄园的管理. During the formation of the feudal society in Western Europe, the natural economy dominated, and the manor organization was the dominant form of the economy. All the manor’s economic activities are mainly to meet the needs of feudal lords in life. With few exceptions, the produce and handicrafts produced by the manor are consumed in the manor. At that time, even if the royal family’s funds were relied on the income of the manor in the territory, the treasury was set within the manor. For the sake of supply, the royal family often moves from one manor to another and consumes the storage in the warehouse on the spot. This shows why Charlemagne did not have a permanent capital for a long time, and why he did not bother with the regulations and participation in the administration of the royal estate.
