Although it took approximately 3 years for my writing to finally culminate in this book, I spent nearly 30 years thinking through related problems to form and streamline a relatively complete system. The main reasons for investing so much time in writing about the fundamental theory of mega infrastructure construction management are as follows:

1. This book contains numerous new academic ideas andtheoretical opinions that require lengthy consideration.

2. Though many of the investigated concepts and theories are independent, they are correlated. The entire theoretical system, which includes fundamental concepts, theories, scientific problems, and methodologies, must be systematic and logical, which requires considerable time and effort to create.

3. The discussed theoretical contents require the guidance and support of construction management practice activities. Accordingly, germination and growth are lengthy processes in producing and achieving the theoretical formation threshold.

4. The content herein fully demonstrates the combination and integration of multiple disciplines, and it also requires the gradual development of an interdisciplinary academic environment.

虽然花了大约3年的时间，我的写作终于达到了这本书的精髓，但我花了近30年的时间思考相关问题，形成并精简了一个相对完整的体系。花这么多时间撰写大型基础设施建设管理基本理论的主要原因如下：

一、这本书包含了许多新的学术思想和理论观点，需要长时间的考虑。

二、虽然所研究的许多概念和理论是独立的，但它们是相互关联的。整个理论体系，包括基本概念、理论、科学问题和方法论，必须是系统的、逻辑的，这需要大量的时间和精力去创造。

三、所讨论的理论内容需要建设管理实践活动的指导和支持。因此，萌发和生长是产生和达到理论形成阈值的漫长过程。

四、本文的内容充分体现了多学科的结合与融合，同时也要求逐步形成一个跨学科的学术环境。
