Replication Data for: When Do UN Peacekeeping Operations Implement Their Mandates?

Under what conditions do UN peacekeeping operations (PKOs) implement the tasks in their mandates? Contemporary PKOs are expected to fulfil increasingly fragmented mandates in active conflict zones. We argue that these two trends—increasingly fragmented mandates, increasingly implemented amidst violence—exacerbate delegation and coordination problems that hinder PKOs from pursuing mandated tasks, potentially undermining their legitimacy in the eyes of the Security Council, troop-contributing countries, and host governments. Combining new datasets on PKO activities and mandates in Africa (1998-2016) and using instrumental variables and two-way fixed effects models, we find that mandate fragmentation is negatively correlated with mandate implementation, especially for peacebuilding tasks. Ongoing violence is also negatively correlated with implementation of peacebuilding tasks, but not with security tasks. We show that this is likely due to the offsetting effects of violence perpetrated by governments and rebels, as PKOs are better equipped to respond to the latter.联合国维和行动（UN Peacekeeping Operations, PKOs）在何种条件下能够切实落实其授权任务？当前，联合国维和行动需在活跃冲突区域执行愈发碎片化的授权任务。我们认为，授权任务愈发碎片化、且愈发在暴力环境中推进这两大趋势，加剧了委托与协调难题，阻碍维和行动落实授权任务，甚至可能损害其在联合国安理会、出兵派遣国以及驻在国政府眼中的合法性。本研究整合了1998年至2016年间非洲地区联合国维和行动活动与授权任务的全新数据集，并运用工具变量（instrumental variables）与双向固定效应模型（two-way fixed effects models）开展实证分析。研究结果显示，授权任务碎片化程度与任务执行度呈负相关关系，在建设和平任务中这一负相关尤为显著。持续暴力冲突同样与建设和平任务的执行呈负相关，但对安全任务的执行并无显著影响。我们的分析表明，这一现象或源于政府与反叛武装所实施暴力的抵消效应——因为维和行动在应对反叛武装的暴力行为时具备更充足的应对能力。
