以新型冠状病毒肺炎（COVID-19）疫情为代表的突发重大公共事件，在对各国经济社会发展产生重大影响的同时，也对伴随“一带一路”建设而稳步推进的中国建造国际化构成了明显冲击。本文首先梳理了代表性的突发重大公共事件及应急管理经验，以仍在进行中的COVID-19 疫情为例，剖析其对中国建造企业国内市场和国际市场的影响；其次以我国某建筑企业海外工程项目实施为案例，通过管理人员深度访谈，深入分析COVID-19 疫情对伊拉克泵站项目在材料与设备、复工与招聘、人员身心健康、项目绩效等方面的影响，对企业应对策略的有效性进行评价。研究表明，为了积极应对突发重大公共事件，政府和企业应当完善突发重大公共事件的应急机制，共享应急管理数据；明确工程材料设备需求量，提前安排运输，关注物流风险，确保项目按期交付；合理增加人员复工补贴，积极实施心理辅导，最大程度地保障项目参建人员的合法权益与身心健康；按需调整项目方案，建立风险缓释机制和长效应对机制，降低项目履约损失。

Major public emergencies represented by COVID-19 have a significant impact on the economic and social development of various countries as well as on China’s construction internationalization which is progressing steadily with the Belt and Road construction. In this article, we first summarize representative major public emergencies and the emergency management experiences, and analyze the impact of COVID-19 on Chinese construction enterprises in domestic and international markets. Subsequently, an overseas engineering project of a Chinese construction enterprise is used as a case for analysis. Through interviews with personnel, we analyze the impact of COVID-19 on the pumping station project in Iraq in terms of materials and equipment, work resumption and recruitment, personnel’s physical and mental health, and project performance, and summarize the effectiveness of relevant coping strategies. Furthermore, to better cope with major public emergencies, we suggest that the government and enterprises should improve the coping mechanism for major public emergencies and share emergency management data. They should also clarify the demand for engineering materials and equipment to plan transportation in advance, and pay attention to logistics risks to ensure that projects are delivered on time. Moreover, subsidies for work resumption should be increased and psychological counseling should be conducted to protect the legal rights and physical and mental health of project staff. Meanwhile, project plans should be adjusted as needed, and a risk mitigation mechanism and a long-term coping mechanism should be established to reduce project performance losses.
