Megaprojects are large and complex projects involving substantial investment, social importance, and long time span. Owing to the multitude of actors involved in such projects, trust plays a critical role in their delivery. This study presents a comprehensive literature review to gather a wealth of information on a variety of research topics on trust in megaprojects. Related publications were analyzed, and 52 relevant papers were selected for content analysis. The final results show that research on trust in megaprojects is still relatively new, thematically diffused, and generally lacking strong theoretical foundations. A further analysis revealed six main research topics involving trust in megaprojects: (i) trust and the success of megaprojects; (ii) institutional/public trust; (iii) trust and megaproject delivery methods; (iv) trust and contracting; (v) trust as a governance mechanism; and (vi) trust as a competence of project managers. The outcomes of this study contribute to the body of knowledge on trust through a comprehensive investigation of the literature in project management and provide guidelines for further research on the phenomenon of trust in megaprojects, as well as project management delivery process in general.

大型项目是大型且复杂的项目，涉及大量投资，社会重要性和较长的时间跨度。由于参与此类项目的参与者众多，因此信任在交付过程中起着至关重要的作用。这项研究提出了一个全面的文献综述，以收集有关大型项目信任的各种研究主题的大量信息。对相关出版物进行了分析，选择了52篇相关论文进行内容分析。最终结果表明，关于大型项目中信任的研究仍相对较新，主题分散且通常缺乏强大的理论基础。进一步的分析揭示了涉及对大型项目的信任的六个主要研究主题：（i）信任和大型项目的成功；（ii）机构/公共信托；（iii）信托和大型项目的交付方式；（iv）信任与订约；（v）信任作为一种治理机制；（vi）信任作为项目经理的能力。通过对项目管理文献的全面研究，本研究的成果有助于增强对信任的认识，并为进一步研究大型项目中的信任现象以及总体上的项目管理交付过程提供指导。
