新时代促使工程师思考工程建设行业当下的困境和未来的发展趋势，立足实践高屋建瓴地创新管理思想。本文基于港珠澳大桥岛隧工程实践，提出“本质管理”理论构念，从实践和词源两个角度诠释“本质管理”的定义，提出本质管理的三个要素和四个内涵，构建了“本质管理”的思维模型，并以港珠澳大桥岛隧工程为例阐述本质管理的过程及方法体系。本质管理是新时代中国工程管理实践的产物，它以中国管理哲学为本，融合古今中外的先进管理思想，重视“人”的主体地位，强调以辩证和积极的观点看待问题，并充分发挥人的主观能动性和创造力，是一种应对严峻工程挑战的、面向工程实践的、具有创新意义的工程管理方法论，其方法体系具有前瞻性和动态适应性。本质管理体现了“本立道生”的朴素哲学思想，对我国大规模工程建设和工程管理具有十分重要的意义和价值。

The new era prompts engineers to consider both the current plight and the future development trend in the engineering industry. Based on the practice in Island & Tunnel Project of Hong Kong–Zhuhai–Macao Bridge, this article raised a new theory of Intrinsical Management and defined it from the aspects of practice and etymology. Then it proposed three factors and four connotations of Intrinsical Management, established its logical model, and elaborated its process and methodology taking the Island & Tunnel Project of Hong Kong–Zhuhai–Macao Bridge as an example. Intrinsical Management is a product deriving from engineering management practices in China, and it integrates Chinese management philosophy with eastern and western advanced management ideas. Intrinsical Management regards human as the most important factor, emphasizes dialectical and positive views, and gives full play to the initiative of human. It is an innovative methodology for solving complicated engineering challenges, and is forward-looking and dynamically applicable to engineering practices. Intrinsical Management presents a simple philosophy of “orientation emerging while root standing”, and has a pervasive significance in large-scale project construction and engineering management in China.
