Abstract: A full understanding of conflict in PM is the basis for efficiently managed conflict. The general features of conflict has been introduced. Then, the characteristics and performance of conflict in civil engineering has been summarized. Besides, this manuscript has systematically reviewed some probable conflict in life cycle of project. Especially, the stakeholders of conflict and its evolution in life cycle are also focused, which can profoundly reveal the cause and influence factor of conflict. Meanwhile, the incompleteness of contract is the contractual factor for conflict. The contract updating is common use for conflict management. Guanxi can be taken as another factor for conflict, which should be concentrated seriously. Trust, promise, communication and cooperation, all of these factors to conflict should be emphasized in conflict initiation and propagation.

Key words: construction, life cycle, project conflict, stakeholder of conflict, cause of conflict

摘要： 充分认识工程项目冲突是高效管理冲突的重要前提。归纳冲突的一般特征，总结工程项目冲突的特点及表现形式；系统梳理全寿命周期内工程项目可能发生的冲突及表现形式；重点研究全寿命周期内项目冲突的主体及演化，揭示冲突形成的事由和影响因素。合同的不完备性是形成冲突的合同因素，合同更新是冲突管理的合同手段；关系作为影响冲突的非合同因素，应重视信任、承诺、沟通、合作在冲突发生发展过程中的重要作用。
