二十一世紀以來的國際發展援助議程益加強調援助有效性，如何確立援助過程中最後階段—政策到發展結果—的有效性，則與2015年 2019年與2021年諾貝爾經濟學獎得主，使用個體資料、應用因果推論方法、進行反事實分析緊密相關。本文回顧援助有效性的背景，介紹反事實分析的邏輯、方法，並透過訪談與文獻分析，檢視臺灣目前政府開發援助中，已獲學術期刊審查刊登的反事實分析案例，包括國際合作發展基金會在南太平洋島國吉里巴斯與馬紹爾群島的園藝計畫以及海地之糧食安全計畫。本文發現上述案例..

Since the beginning of the twenty-first century, the international development agendas have put more emphases on aid effectiveness. How to ensure the effectiveness from policies to development outcomes, the last stage of the aid process, is closely related to counterfactual analyses using micro-level data and causal inference techniques, recognized by Nobel Memorial Prizes in economics in 2015, 2019, and 2021. This paper reviews the background of aid effectiveness, introduces the logic and techniques of counterfactual analyses commonly used..

本體論為任何研究之始，能動者 / 結構爭論為以 Waltz 為首之結構現實主義與 Wendt 為代表之建構主義在本體論層次的重要歧異點之一，為此，兩派學者自 1980 年代末黨論戰迄今。儘管本體論的問題具有政治性，不見得有終極與明確的答案，但籍由本體論的討論可以讓吾人更能瞭解兩派理論在深層假設的異同。本文在敘明能動者/結構爭論在理論發展上的重要性後，進行爭論中相關重要概念——如能動者、能動性、結構等——的闡述，除追蹤這些概念在社會學上的根源..

All research begins with ontology. The agent/structure debate represents one of the most profound discrepancies and the least conclusive contests in this regard between Structural Realism and Constructivism since the late 1980s. Though politics is the terrain of competing ontology；definite and clear-cut answers are hardly attainable, a serious discussion on ontological issues can lead us to penetrate the assumptions deeply embedded in both theories. This article first examines theoretical significances in the agent/structure debate and ..
