摘要:目前人们在对工程项目组织的研究中，通常将工程项目组织视为“他组织性”的组织，这种认识是刚性的，忽视了人的主观能动性。工程项目组织在其全寿命期内，组织形式随着时间不断的变化，是工程项目组织不断适应环境和任务需要的结果，是工程项目组织自我组织的外在表现。从系统理论出发，工程项目组织包括若干个子系统，通过布尔代数运算，结果证明工程项目组织具有鲜明的“自组织”特性，工程项目组织是一个需要人工调节的自组织系统，为工程项目组织设计提供一种新的思路和方向。

Abstract: Construction project organization is usually regarded as 'organized' organization during the research at present and this recognition is rigid because the people's initiative is ignored. The form of changes in construction project organization in its life cycle is the result of the process that construction project organization is adapting to the environment and requirement of mission constantly, and the result is the exterior manifestation of self-organization about the construction project organization also. The construction project organization includes some sub-systems from the system theory. Through Boolean algebra calculation, there have been distinct characters of 'self-organization' in construction project organization by analysing the result, and the construction project organization is self-organization system which needs to adjust manually. The conclusions list above provides a new way of thinking and direction for the design of construction project organization.
