一句话：用纵向混合方法研究开源治理的采纳、文档化与影响，揭示治理是 OSS 可持续性的社会技术基础。
开源软件依赖可持续的社区，但许多项目面临决策瓶颈、贡献者参与路径不清以及责任分配不均等问题。治理规定了社区中权威如何组织，然而其对贡献者体验与项目健康的影响仍缺乏理解。本文的研究覆盖治理的完整生命周期：治理改革如何影响协作；角色、职责与权威在实践中如何被成文规定；治理结构如何在社区内部协商并被接受。作者对 data.table 项目开展了纵向混合方法研究，表明由社区协作设计的治理模型改善了贡献者响应速度、新人上手与留存；同时对 GitHub 上治理文档的更广泛分析发现，权威形式化方式存在显著差异，说明在更清晰的参与路径上仍有改进空间。该工作将治理的采纳、文档化与影响联系起来，把治理理解为可持续开源开发的社会技术基础，并为社区治理实践与工具支持提供实证依据。
Open source software depends on a sustainable community, yet several projects struggle with decision-making bottlenecks, unclear contributor pathways, and uneven distribution of responsibilities. Governance defines how authority is organized in these communities, but its influence on contributor experience and project health remains poorly understood. My research investigates governance across its full lifecycle: how governance reforms affect collaboration; how roles, responsibilities, and authority are codified in practice; and how governance structures are negotiated and accepted within communities. Using a longitudinal mixed-methods study of the data.table project, we showed that a collaboratively designed governance model improved contributor responsiveness, onboarding, and retention. A broader analysis of governance documents across GitHub revealed substantial variation in how authority is formalized, indicating opportunities for clearer pathways. By connecting governance’s adoption, documentation, and impact, this work advances a deeper understanding of governance as a sociotechnical foundation for sustainable OSS development.
