一句话：纵向分析 Flutter 社区贡献者人口属性对生存的影响，发现隶属机构/西方背景者生存概率更高，性别差异不显著。
开源项目普遍面临贡献者高流失率，部分项目人员更替率高达80%。贡献者的生存性受人口统计因素影响，因此研究留存必须纳入多样性维度。本文以 Flutter 社区为对象，从性别、地区和薪酬/隶属状态三个维度进行纵向分析，考察人口属性对贡献者生存概率的影响。初步结果显示：有隶属机构或来自西方国家的贡献者，其生存概率高于志愿者或非西方国家贡献者；而男性与女性贡献者之间未发现显著生存概率差异。研究强调多样性因素对开源可持续性的重要性。
Maintaining and retaining contributors is crucial for Open Source (OSS) projects. However, there is often a high turnover among contributors (in some projects as high as 80%). The survivability of contributors is influenced by various factors, including their demographics. Research on contributors’ survivability must, therefore, consider diversity factors. This study longitudinally analyzed the impact of demographic attributes on survivability in the Flutter community through the lens of gender, region, and compensation. The preliminary analysis reveals that affiliated or Western contributors have a higher survival probability than volunteer or Non-Western contributors. However, no significant difference was found in the survival probability between men and women.
