[目的/意义]通过分析国外数字游戏长期保存的研究进展，为我国发展数字游戏长期保存提供借鉴。[方法/过程]以文献调研为基础，对所得文献的研究内容从数字游戏保存的内容、数字游戏的法律问题、数字游戏长期保存的技术和各界对数字游戏长期保存的态度4个主题进行总结分析。[结果/结论]国外数字游戏长期保存存在4个特点：研究主体范围广，但是研究人数少；技术研究多以项目的形式呈现，研究项目大多受到研究机构/计划资助；研究方法多样；不同研究主题的研究程度不均衡，未形成完整的体系。我国可以从中获得的3个方面的启示：全面调研我国数字游戏保存的现状；加强理论研究，夯实理论基础；加强各界合作，参与国际合作。
[Purpose/significance] Based on the analysis of the status of the research in long-term preservation of digital games in abroad, this paper aims to provide development proposals for the digital game preservation in China.[Method/process] This paper conducted literature research through multiple channels, and analyzed these literature from the perspective of research topics, including the content of digital game preservation, the legal issues about digital game preservation, the technology and the attitude from all walks of life towards the preservation of digital games.[Result/conclusion] There are four characteristics of the research of digital game preservation in abroad:the research subjects cover a wide range, but the number of researchers is small; most of the technical research are in the form of projects, most of which are funded by research institutes; methods are diverse; the degree of research among the subjects is not balanced, and the research of digital game preservation has not formed a complete system. The three enlightenments to the development of digital game preservation in China are:investigate the status quo of digital game preservation in China; strengthen theoretical research and take an active part in cooperation.
