受到 1980 年代起國際關係理論第三次大辯論的影響，政治地授學者與國際關係學者也將後設理論的爭論帶進地緣政治研究，後現代地緣政治或批判性地緣政治是運用後結構主義、後現代主義與批判理論作為其論述的哲學基礎。批判性地緣政治是質疑傳統地緣政治的本體論與知識論的前提假定，解構傳統地緣政治對世界政治的觀察，以及挑戰其以國家為中心的政治實踐。也就是解構傳統地緣政治的霸權論述，以及質疑在主要強國的地緣政治實踐所發現的權力關係。批判性地緣政治研究影響了地緣政治研究的方向與內涵，擴展了其研究議題，但要改變地緣政治研究的主流或是世界政治仍是需要持續不斷的努力。但對台海兩岸關係研究仍是有些啟示，可以提供不同於現有的政治地緣論述。

Due to the influence of the third Great Debate on International Relations Theory in the 1980s, scholars in Geopolitics and International Relations have brought the debates of metatheory into geopolitical research. They have used Post structuralism, Postmodernism, and Critical Theory philosophical foundations to question traditional geopolitics about its ontological and epistemological assumptions, to destructure its perspectives on world politics, and to challenge its state-centered political practices. Therefore, they have been called the Critical Geopolitics or Postmodern Geopolitics. The Critical Geopolitics wishes to destructure the hegemonic geopolitical discourses of the major powers and to question the power relations expressed by the major powers in political practices of the world.

Critical Geopolitics has influenced the directions and contents of geopolitics, and has also extended the research agenda of geopolitics However, it needs much pertinent efforts to change the main courses of geopolitics and world politics. Even though, there are some implications for geopolitical imagination of Taiwan, to provide a different critical geopolitical discourse.
