当前，我国经济快速增长，工程建设的规模日益扩大，诸多大型工程相继完工并投入使用，工程管理实践日新月异；与此同时，学者对工程管理也在不断地总结归纳，并努力逐步形成工程管理理论体系，探究工程管理理论体系的核心成为构建工程管理理论体系的关键。本文通过研究我国工程管理的理论和实践，初步总结出工程管理理论的核心：“以人为本，天人合一，协同创新，构建和谐”，并试对工程管理做了全面的定义。希望有助于工程管理理论体系的研究。

At present,China's economy is in rapid growth. The scale of engineering construction is increasing significantly and a number of major construction engineering projects have been completed or put into use. So the engineering management practice is facing new challenges with each passing day. In the meanwhile,our scholars are constantly summarizing what they have learnt in these activities and gradually establishing their own engineering management theory system,in which exploring the core thought of engineering management theory system becomes critical. By studying our engineering management theory and practice,this paper preliminarily sums up the core thought of the engineering management as "people-oriented, harmony between nature and humanity,collaborative innovation,building a harmony among people,society and nature", and a comprehensive definition of engineering management is made, with a hope to help the research on engineering management theory system.
