美国教育、科技、经济、军事“四维一体”的互动关系是美国综合国力的重要源泉。本文描述了“冷战”结束以来，美国在政策和投入层面如何维护或提升这四个因素并使之相互结合，从而继续维持其综合国力和世界霸权地位的过程。本文认为，一旦上述四个关联因素中的某个因素受到严重损害，或者不能做到“四维一体”式的相互结合，那么，其综合实力和霸权地位就将受到损害。
The article argues that the U.S. system of educational, scientific& technological, economic and military development, or a tetrad interaction of the above four factors, is a key to understand the U.S. national comprehensive power. Since the end of the Cold War, the U.S. has strategically restructured the policy towards, and budget for, education, science and technology, economy and military development. The report argues that the U.S. has basically maintained its national comprehensive power, retaining its world hegemony. If any of the four factors was seriously hurt, or the tetrad combination could not be achieved, the U.S. national comprehensive power and its world hegemony would be endangered in coming years.
