在工程的全生命周期中，工程运营阶段的历时最长、成本投入最大，且是工程效益体现的主要环节。在工程运营阶段的成本投入中，能源、人力资源及设备更新占了很大的比重，对这些成本的有效控制，是信息化实现的重要目标之一；在工程运营阶段，工程管理机构与客户及合作伙伴共同构成信息化的主体，工程利益相关者的有效协作是信息化成功的关键所在，本文以机场信息化为例，对工程管理信息化的继承与创新进行了探讨。

During the life-cycle of the large projects,the operational phase which lasted the longest and cost the most,is the major link project benefits reflected. In the whole phase, energy, human resources and the equipment maintenance may cost a lot. Effective control of such cost is one of the main targets of engineering management informatization(EMI). In the phase of project operation, project management institution,customers and partners are the stakeholder of EMI. Through the case of the airport management informatization, inherited and innovation of EMI has been discussed.
