为有效控制、规避及减少港珠澳大桥岛隧工程设计施工总承包招标风险，保障招标工作圆满完成及顺利实施。在对招标风险特征详细分析及识别的基础上，系统构建出招标风险层次结构，并采用层次分析法分析找出招标风险应对的重点，研究形成风险应对措施。研究与实践表明： 1）对该类项目进行全面、系统的招标风险评价与应对是必要的； 2）划分3个层级的风险层次结构可有效保证全面、系统地评价该类项目招标风险； 3）采用层次分析法对该类项目进行招标风险研究是恰当、有效的，可以有效判别各类风险因素的重要性，并能有效应对； 4）培育招投标市场、系统梳理法律法规支撑点、建立设计与施工有效联动机制等应对措施是可行、有效的。

It is very important to effectively control, evade and reduce the risk of bidding for the island and tunnel designconstruction contracting of HongkongZhuhaiMacao Bridge Project, and guarantee the successful completion and smooth implementation of the bidding. On the basis of the detailed analysis and identification of the characteristics of the bidding risk, a hierarchical structure of the bidding risk is systematically established; the analytic hierarchy process （AHP） is used to find out the key points of the bidding risk; and some countermeasures for the risk are studied. The study and practical results show that: （1） It is necessary to carry out comprehensive and systematic risk assessment and response to this kind of project. （2） By classifying the hierarchical structure of the risk into three parts, the comprehensive and systematic assessment of the biding risk of this kind of project can be guaranteed. （3） The AHP is appropriate and effective in terms of analyzing the bidding risk of similar projects, which can effectively identify the importance of each rick factor and carry out corresponding countermeasures. （4） The countermeasures, i.e. developing bidding market, systematically compiling legal support and establishing effective linkage mechanism between design and construction, are feasible and effective.
