中国工程管理的理论研究总是沿袭西方项目管理知识体系的思想，缺乏对具有本土特色的逻辑严密、层次分明的理论体系进行深入系统的分析和研究。本文遵循从抽象到具体的逻辑过程，按照科学的理论体系构建方法，构建了工程管理理论体系概念模型，即“树”模型。“树”模型将工程管理的基础理论、主体理论以及应用理论有机地联系起来，同时生动地体现了理论研究与实践，理论发展与环境之间的互动关系，具有开放、动态、发展的特点。

The theory research of engineering management in China always follows the idea of western project management knowledge system. There is lack of the logic and structured theory system with local characteristics, which needs to be closely analyzed and studied. This paper establishes the engineering management theory system conceptual model,which is the "tree" model,according to the scientific constructing methods abide by the logic process from abstract to concrete. The "tree" model organically links the basic theory,main theory and applied theory, vividly embodies the interactive relationship between theory research and practice,theory development and environment, and has the characteristic of opening,moving and developing.
