At present, China’s economy is in rapid growth. The scale of engineering construction is significantly increasing and a number of major projects have been completed and put into use, bringing the engineering management practice new issues and challenges with each passing day. In the meantime, Chinese scholars are constantly summarizing what they have learnt in these activities and making great effort to gradually establish their own theoretical system of engineering management, of which the core essence of theoretical system of engineering management becomes a critically important topic. By studying our engineering management theory and practice, this paper preliminarily sums up the core essence of the engineering management theory in China as: “establishing a perfect harmony between human and nature through a people-oriented approach and dual innovation”, with a hope to help and enrich the research on the theoretical system of engineering management in China.
