2010年中國漁船與日本海上保安廳巡邏船於釣魚臺相撞之後，中國向日本禁運稀土，此例成為經濟脅迫的一個顯著案例。2019年左右中國官方媒體又再次將稀土視為與美國貿易戰的武器，此使中國的稀土政策、稀土供應鏈的韌性重新成為人們關注的焦點。為了確定稀土用於經濟制裁或經濟脅迫時的有效性，我們有必要重新審視中國2010年對日本進行稀土禁運案例。本文重新審視了當時日本政府對於中國對日禁運稀土所採取的一連串政策回應，並檢視2010年後日本與稀土相關的經濟安全政策。此外，基於此案例，本文發展出評估單一國家..

China’s media has reported multiple times that the country could use its rare earth exports as a countermeasure against the United States since the Trump administration launched its trade war. President Biden has sought international cooperation to bolster supply chains and counter China’s economic coercion, and rare earth elements have been identified as the key resources in this campaign. To determine whether rare earth elements can be used effectively in economic sanctions, we must re-examine China’s 2010 embargo on rar..

本研究目的在建立美國傳統戰略模糊與臺灣避險策略間之理論關聯性。主要假設當臺灣從美國獲得較多且明確之安全承諾時，將可能更依賴美國安全保護傘，進而降低自身制定外交政策之自主與靈活性。過去數十年，華盛頓持續且長期的安全承諾，即有可能限制臺灣的避險策略選擇。本研究的實證證據，主要探討川普與拜登政府任內，華府戰略模糊逐漸轉變為戰略清晰下，臺北在美中兩強之間的外交政策。此外，藉由將避險的理論「模型化」，並區別避險與樞紐的關係，是本文另一個研究貢獻。

The study aims to establish a theoretical connection between strategic ambiguity and hedging policy. The assumption is that as Taiwan receives more security assurance and clarity from the United States, it may rely more on the U.S. security umbrella, reducing its autonomy and flexibility in crafting its foreign policy. Over time, consistent and prolonged security commitments from the United States could limit Taiwan’s hedging options, as it increasingly aligns with the U.S. position. The empirical evidence in this article explores how..

近年來，中美兩強權在印太地區的戰略競爭愈演愈烈。特別是在基礎建設上，所謂的聯通性戰略，更是兩國在印太地區較量的指標。隨著經濟的快速發展，印太地區對數位化所需的基礎建設越顯急迫。在新冠疫情後，印太國家更加關注高質量的網路基礎設施以及一些關鍵的數據驅動技術，包括人工智慧（AI）。因應此需求，中國早在「一帶一路」（Belt and Road Initiative, BRI）的旗幟下，提倡「數位絲綢之路」（Digital Silk Road, DSR），積極推進數位基礎設施合作。美國則提出了「自..

In recent years, the strategic competition between China and the United States in the Indo-Pacific region has intensified, particularly in the realm of infrastructure development. The concept of connectivity has become a key indicator of this competition, as both countries seek to expand their influence in the region. With the rapid economic growth, the demand for digitalizationrelated infrastructure in the Indo-Pacific region has become increasingly critical. In the post pandemic period, Indo-Pacific countries are more concerned about high..

對於強權並存且有爆發戰爭可能性的國際格局，戰爭由誰引發在學界的論點迥異。權力轉移理論認為崛起國基於不滿現狀，會對主導強權發起戰爭；另有聲音則認為衰退的國家基於預防性動機，會對崛起的對手採取行動；然而，權力轉移理論與預防性動機的論述，主要關注於戰爭的發動，此觀點反映一種以「戰爭」進行解析的框架，即探討國與國之間是否會發生戰爭。本研究則以另一個「非戰爭的攻防」的分析框架，論述主導強權與崛起國之間在兵戎之外的攻防行動。本文以美國在2022年施行的晶片與科學法案為例，論述美國對中國採行的非戰爭預..

In the international arena where powerful nations coexist, and the possibility of war exists, there are differing opinions on who triggers wars. Power transition theory suggests that a rising power will initiate war against a dominant power out of dissatisfaction with the status quo. Other argue that the declining state is motivated by preventive motivation to take action against rising adversary. However, both the power transition theory and the preventive motivation argument primarily focus on the initiation of war. This perspective refle..

由於提供數位經濟服務的跨國公司不須在市場國建立恆久據點，導致利潤來源地政府無法適用傳統的常設機構原則進行課稅。面對此項國際稅收分配的挑戰，經濟暨合作發展組織（Organisation for Economic Cooperation and Development, OECD）在2013年公告「防止稅基侵蝕與利潤移轉計畫」 （BEPS），試圖建立一致的課稅替代方案。然而，部分國家後續卻自行開徵數位服務稅，美國川普政府對這些國家威脅使用301條款並發起關稅報復，直到2021年美國拜登政府支..

Host countries cannot tax digital multinational corporations (MNCs) based on the traditional permanent establishment principle because digital services are intangible. To address this challenge, the Organisation for Economic Cooperation and Development (OECD) initiated the “Base Erosion and Profit Shifting” (BEPS) multilateral regime in 2013. Nonetheless, several host countries hunting for revenue unilaterally adopted digital service taxes, and the US Trump administration responded with Section 301 tariff retaliation from 2019 t..
