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.

公私協力夥伴關係近年來成為南南合作的重要模式，隨著自身經濟實力的增長，南方國家廠商也開始參與其他發展中國家興建基礎建設。有鑑於先行文獻對此現象經常採行對外直接投資的研究框架，較為輕忽公共建設的特質與偏重投資的負面效果，本文以中國廠商參與泰國與緬甸的海外公共建設項目為例，進行理論建構工作。研究發現民營企業即使獨資取得地主國的公私協力夥伴計畫，也不致於衍生爭議;相對地，中央型國有企業參與基礎建設計畫較易遭遇政治反抗，但如果採行與當地或者他國際廠商的合資形式，則可..

South-South Cooperation is believed to facilitate development smoothly. However, why do some projects of public-private partnership in infrastructure (PPI) between Southern countries create contention while others do not? This research argues that types of enterprises and interfirm cooperation are two determinants of contentious politics against foreign involvement in PPI in Southern countries. To explain how this mechanism works, I focus on Chinese firms’ port and power construction PPI in Thailand and Myanmar. The com..
