戰略觀點下的國家權力分析

Analysis of State Power from a Strategic Perspective

在當代國際關係研究中，國家權力（National Power）的評估往往集中在其物質性要素，例如經濟規模與軍事力量。然而，一個國家擁有壓倒性的資源，並不能保證其必然獲得戰略上的成功。本文旨在回應此一理論困境，主張必須從「大戰略」（Grand Strategy）的角度，才能有效分析國家權力的實踐。本文的核心論點是：國家權力的有效性，並非取決於權力資源（手段, Means）的總量，而是取決於政治目標（目的, Ends）、戰略構想（方法, Ways）與可用資源（手段, Means）三者之間是否達成「邏輯連貫性」。
為驗證此論點，本文首先建構一個整合性的「目的-方法-手段」（E-W-M）分析架構。其次，本文解構國家權力的各項構成要素（軍事、經濟、外交與軟實力），並將其定位為大戰略中的可用「手段」。最後，本文以此架構進行實證分析，深入檢視美國大戰略的歷史實踐—從冷戰時期的「圍堵」（Containment）到後冷戰時代的「反恐戰爭」與當代大國競爭。
研究發現，美國的戰略成功（如冷戰）源於E-W-M架構的相對統一；而其戰略失敗（如阿富汗戰爭）則源於此一邏輯鏈的斷裂，特別是政治「目的」的混亂與國內政治對「方法」的扭曲。本文結論重申，脫離了戰略思維的權力分析，將淪為靜態的資源盤點，無法真正解釋國家行為的成敗。

In contemporary International Relations scholarship, assessments of national power frequently privilege material attributes, such as economic scale and military capabilities. However, the possession of overwhelming resources does not guarantee inevitable strategic success. This article seeks to address this theoretical dilemma by arguing that the operationalization of national power must be analyzed through the lens of Grand Strategy. The central thesis is that the effectiveness of national power depends not on the aggregate volume of power resources (Means), but rather on the achievement of“logical coherence”among political objectives (Ends), strategic concepts (Ways), and available resources (Means).
To validate this argument, this study first constructs an integrated“Ends-Ways-Means”(E-W-M) analytical framework. Second, it deconstructs the constituent elements of national power—military, economic, diplomatic, and soft power—positioning them as the available“Means”within a grand strategy. Finally, utilizing this framework, the article conducts an empirical analysis of the historical practice of U.S. grand strategy, ranging from the Cold War policy of“Containment”to the post-Cold War“War on Terror”and contemporary great power competition.
The findings indicate that U.S. strategic successes (e.g., the Cold War) stemmed from a relative alignment within the E-W-M framework, whereas strategic failures (e.g., the War in Afghanistan) resulted from a rupture in this logical chain—specifically, the confusion regarding political“Ends”and the distortion of“Ways”by domestic politics. The conclusion reiterates that an analysis of power divorced from strategic thinking descends into a static inventory of resources, failing to adequately explain the success or failure of state behavior.
