现代工程项目管理在我国经过二十多年的发展，管理水平得到了较大的提高，但目前仍存在着法律法规不健全、监督机制不完善、建筑工程模式单一、项目参与方缺乏相互协作的观念等问题；在加入WTO以后，我国的建筑工程行业又面临着与经验丰富、技术实力雄厚的国外大型建筑工程企业的正面竞争，解决我国的建筑工程项目管理问题成为当务之急。基于这种背景，本文对我国工程项目管理中的主要问题进行了系统的研究并给出了相应的解决对策，为解决我国工程项目管理问题做了一些有益的探索。 在以往的研究基础上，本文提出基于政府、业主、承包商三方系统协作的研究视角，对我国工程项目管理中存在的主要问题进行综合研究并给出相应的对策；与以往仅对项目某一参与方研究的观点相比，避免了对项目实施过程中存在问题相互推诿和对策无法落实的局面。在研究线路方面：以系统协作、信息共享为主线，将项目主要相关方对项目交付结果的满意程度作为评价准则，对项目实施过程及交付结果进行控制与评价。 在论文中首先对政府、业主、承包商在工程项目管理中的职责、存在的问题与原因进行详细的分析。然后，对传统项目管理模式中项目参与方之间监督、约束关系进行研究，证明了基于相互监督、约束的传统项目管理模式并不是最优的管理模式并论证了项目参与方之间实施系统协作的可行性。最后，给出了解决我国工程项目管理中存在问题的对策建议：第一、项目各参与方应转变思想观念，建立基于系统协作的项目管理理念；第二、项目各参与方之间应建立以项目为纽带的协作、共赢的协作伙伴关系；第三、对我国的常用项目管理模式与国际新兴项目管理模式的特点进行研究，便于项目参与方根据项目的特点选用最优的工程项目管理模式。

The level of construction project management has been highly improving by its more than 20 year’s development. However, there are still many problems: imperfect laws and regulations, the lack of supervision, single construction project mode, the shortage of cooperation idea among different participants of project. With the entrance of WTO, construction trade which has lots of project management problems, confronts fierce competition from foreign construction companies with rich experience and high technology. Therefore, it is necessary to solve those problems .Based on this environment, the systematic research on the project management problems, is done in this thesis and its countermeasures are also given , in order to do some good probe for project management . On the ground of past research, this paper explores our project management problems from the perspective of the systematic cooperation among the government, owner and contractor .The corresponding measures are given through the research of these problems. Comparing with the only research on some participants, it avoids the situation of mutual evading problems and un-implementation of countermeasures. About the research route, it emphasizes the systematic cooperation and information share, and puts customers’ satisfaction as evaluation rule to control and evaluate the implemented process and the achievement. The main part of the thesis . First, the paper discusses and analyzes the problems and reasons in project management among the government, owner and contractor. On this basis, through the theoretical research of traditional project management, it proves that the mode of project management based on mutual supervision and constraint is not the best. And it proves the feasibility of systematic cooperation among different participants .At last, the countermeasures to above problems are given: first , every part should establish the project management ideas based on systematic cooperation of all participants. Secondly, participants should establish a long win-win partnership tied with projects and ensure the efficiency and profit of participants .Last, in terms of the study on the features of our common project management modes and international advanced ones, participants can choose the optimum mode according to specific project characteristic.
