笔者从重大建设工程技术创新的特点和现状分析入手，剖析制约重大建设工程技术创新的核心障碍，建立面向重大建设工程技术创新网络的基本架构，分析其形成起点、演化路径和整合方式，探讨技术创新网络的动力机制、协同机制和学习机制，为建立跨组织协同的新型技术创新模式，提高重大建设工程技术创新效率和水平提供理论依据。

The characteristics and the present situation of significant construction project technological innovation are analyzed in this paper. The core problem restricting significant construction project technological innovation is dissected. The basic framework of significant construction project-oriented technological innovation network is set up. Then the starting point, evolution path and integration method are analyzed. And the dynamic mechanism, the collaborative mechanism and the learning mechanism are discussed,which can provide useful theoretic reference to establish the new inter-organization coordinated technological innovation mode, and to improve the technological innovation efficiency of significant construction project.
