探明数字人文项目失败的成因机理对数字人文可持续开发至关重要。文章以2014年-2023年国际数字人文奖中的22个“最佳数字人文失败探索奖”为数据来源，通过案例内容分析，结合文献调研与项目实践经验，分阶段、多维度剖析数字人文项目失败的潜在成因及其应对策略。研究发现，数字人文项目在开发前期存在规划层、素养层、伦理层问题，在开发中期存在法律层、技术层、人员层问题，在开发后期存在资金层、保障层、归档层问题。基于此，针对性地从战略规划、执行操作、保障支持三个维度，提出未来数字人文项目在不同开发阶段的有效对策，助力数字人文项目开发的可持续性。

Exploring the causal mechanisms of digital humanities projects failure is critical to digital humanities sustainability. Using the 22 “Best Exploration of DH Failure” from the 2014-2023 Digital Humanities Awards as the data source, we analyze the potential causes of digital humanities projects failure and their coping strategies in a phased and multi-dimensional way through case content analysis, combined with literature research and practical projects experiences. It is found that digital humanities projects have problems at the planning, literacy and ethical levels in the early stage of development; at the legal, technical and personnel levels in the middle stage of development, and at the financial, guarantee and archiving levels in the late stage of development. For this reason, the study proposes effective countermeasures for future digital humanities projects at different development stages from the dimensions of strategy and planning, implementation and operation, guarantee and support, so as to help the sustainability of the development of digital humanities projects.
