海洋始终是美国全球战略体系的重要支撑。第二次世界大战结束以来,美国长期依托压倒性的海上力量优势维系其全球领导地位,并将控制海洋视为国家安全战略和大战略的前提。然而,随着美国全球海上格局逆转、海上力量对比巨变和美国国内政治极化,美国维持传统海上优势的成本与难度显著上升,海上战略理念与力量运用方式正在发生重要变化。为此,美国通过向盟友转嫁成本,强化水下与无人体系、振兴海洋基础设施及制造业等方式,试图在全球重点海域维系对美国有利的力量平衡。
清华大学战略与安全研究中心特约专家、中国论坛特约专家,北京大学国际关系学院研究员、“南海战略态势感知计划”主任胡波在《外交评论》撰文,考察美国海上战略由追求绝对优势向接受海上均势与战略拒止转变的过程,分析推动这一调整的结构性因素及其战略逻辑。从长周期来看,这一转变有利于缓解其与中国等大国的地缘政治矛盾,促进世界和平与稳定,但短期来看,可能会加剧热点海域的局势动荡。

霍尔木兹海峡遭到伊朗和美国的实质性封锁后,所造成的风险迅速传导到国际油价、航运、保险和金融市场。美国能源信息署的最新分析显示,2024年经霍尔木兹海峡运输的油气规模相当于全球石油和石油产品消费的约1/5,经此运输的全球液化天然气贸易大概也是这个比例,其中大部分流向亚洲市场。然而,当韩国、日本及东盟国家的经济和能源安全受到直接冲击时,中国却稳如泰山,至今没有释放战略石油储备,4至5月国内5500大卡动力煤长协价稳定在685~689元/吨,现货涨幅不到1%,显著低于国际市场(约20%),油气电力价格未现系统性波动,“中东一动荡,中国能源安全立刻被动承压”的逻辑被进一步改写。原因何在?启发何在?

Guided by the Center for International Security and Strategy (CISS) and the Center for Global Competence Development at Tsinghua University, the Tsinghua University Student Association of International and Strategic Studies (SAISS) brings together students from across the university who aspire to pursue careers in diplomacy, international affairs, and global engagement. The association is committed to broadening students' global perspectives, strengthening strategic thinking, deepening their understanding of China's national development, and enhancing their ability to present China's perspectives effectively to international audiences. Through research, public communication, and peer learning, SAISS seeks to foster a student-led think tank for the next generation of Chinese youth.
