中小型國家在當前國際體系下的數目眾多，這些國家有各自國家利益與偏好，因此理解這群國家的策略選擇可以更全面地了解國際關係發展。本文研究設計有以下幾個特色：第一，本文以歐洲的中小型國家為個案研究標的，擇立陶宛、匈牙利與土耳其三國進行分析，這三國分別位於當前東／西歐對立環境的最前沿，透過觀察這些國家可理解地緣斷層帶上中小型國家面對歐、俄強權競爭時的策略選擇。第二，由於中國近年不斷向歐洲拋射影響力，歐洲國家明顯感受到中國政策影響，歐洲的中小型國家傳統上面對歐／俄兩強環境已出現變化，由於中國不斷崛..

Small and medium-sized states constitute a substantial portion of the contemporary international system. These states possess distinct national interests and preferences; hence, examining their strategic choices provides a more nuanced understanding of the dynamics of international relations. This study is characterized by several key features. First, it focuses on European small and medium-sized states through the case studies of Lithuania, Hungary, and Turkey. These countries are situated on the geopolitical frontlines of the current East..

2016年日本通過宇宙2法，揭櫫推動民間升空商機、遙測數據商業等目標，目的在於擴大日本太空商業活動與世界太空市場接軌。其次，2017年美國NASA公布「阿緹米斯計畫」（Artemis program），基於美日同盟和美日安保，日本也積極參與美國主導的月球計畫；日本第5期《宇宙基本計劃》（2023∼2033年）表明日本邁入國際太空合作的動向，並且推出「宇宙安全保障構想」。就此，本文整理日本對應新太空時代的動向、太空與安保、太空民主聯盟等觀點，採用理性抉擇理論的「偏好—機..

In 2016, Japan passed the Space Act which aims to promote private space launch opportunities and the commercialization of remote sensing data, with the goal of expanding Japan’s space commercial activities and aligning with the global space market. Secondly, in 2017, NASA announced the Artemis program (Lunar Program). Based on the U.S.-Japan alliance and U.S.-Japan security arrangements, Japan is also actively participating in the U.S.-led lunar program. The 5th Basic Plan for Space Policy (2023~2033) indicating Japan’s move tow..

非傳統安全指的是除了戰爭外其他會威脅到國家安全的議題，在全球化的局勢下這些議題的重要性與日俱增，然而文獻上少有對這個國際關係的第三大次領域系統性的整理，本文討論非傳統安全的三大重要主題—能源安全、環境議題、恐怖主義，以及其他議題如糧食安全、移民與難民議題、跨國犯罪、以及傳染病，除了回顧相關文獻並探討其趨勢外，本文認為非傳統安全的議題仍不斷在擴充中，並點出全球化下科技在這些議題中扮演的重要角色。

Non-traditional security (NTS) issues refer to any issues other than wars that will threaten national security. The importance of NTS issues has been increasing as globalization has accelerated. The literature, however, lacks a systematic review of NTS research, which is arguably the third largest subfield in international relations. This paper focuses on three major NTS issues—energy security, environmental issues, and terrorism, and also briefly discusses other NTS issues, including food security, migration and refugees, transnation..

臺灣民眾自我防衛的決心，對於我國國防及東亞區域和平皆有重大影響。尤其是在面對可能的兩岸衝突狀況下，了解臺灣民眾的自我防衛意 願，與國家安全息息相關。然而，如何解釋臺灣民眾自我防衛決心的差異，在現存的國際關係文獻裡面的討論有限。我們認為，民眾在理性計算是否願意參戰時，過去的從軍經驗是心理上最直接仰賴的資訊，因此從軍經驗的好壞，理論上會影響民眾的自我防衛決心。本文把從軍經驗分成三個面向，包括軍種、覺得軍事訓練對上戰場的有用程度、以及從軍時與長官的相處狀況，並於2..

What explains Taiwanese citizens’ determination of self-defense? To date, few studies touch upon this issue. We argue that one’s military service experience is an important factor for studying citizens’ willingness to fight and hypothesize that positive experience could be conducive to higher willingness for self-defense as the citizens feel they have the capabilities and preparations for a conflict. We operationalize military service into three dimensions: military branch, evaluation of usefulness of milita..

中國自1978年改革開放以來，隨著快速的工業化與城市化的發展，國家糧食安全與糧食自給率的確保一直受到高度的重視。然隨著2001年加入世界貿易組織，國際農產品貿易日趨熱絡，糧食自給率逐漸下降，因此引發一個問題，即中國糧食安全程度是否逐漸惡化?糧食安全與貿易自由化是互補關係，抑或是互斥關係?本研究利用經濟學人信息社(Economist Intelligence Unit，以下簡稱:EIU)建構的全球糧食安全指標(Global Food Security Inde..

Food self-sufficiency rate has been the major food security indicator for policy decision-making in China for a very long time. However, after reform and opening the country with increasing international trade, the self-sufficiency ratio of food has gradually decreased, which raises the question, is there a gradual deterioration of China’s food security? This study uses the Global Food Security Index (GFSI) constructed by the Economist Intelligence Unit (EIU), consisting of three sub-indexes, namely affordability, avail..
