通过文献研究、现场调研以及访谈等方式，认为工程需求、组织、资源、制度是重大建设工程技术创新网络的4个协同要素，构建由合作机制、利益机制、激励机制和评价机制组成的协同机制模型，并论证通过协同机制的有效运行，能够提升重大建设工程技术创新能力和效率。 本研究为建设工程技术创新网络理论研究的组成部分，对建设工程技术创新实践活动以及制定行业技术创新政策具有一定的理论参考价值。

Through the literature research as well as field survey and interview, the engineering requirement, resource integration, organizational synergy and institutional guarantee are chosen to be the key synergetic elements. The synergetic mechanism model consisting of cooperation mechanism, benefit mechanism, motivation mechanism and institution mechanism is also constructed. Besides, the effective operation of synergetic mechanism is proved to be functional to improve the ability and efficiency of technology innovation for major construction projects. This paper which is part of the theoretical research on the technology innovation network for major construction projects will provide some valuable theoretical guidance for the technology innovation practice and the technology innovation policy make of the industry.
