世界地理结构与美国的全球战略及军力设计

This paper examines the effects of the world geographical structure on national security strategy and military force design of great powers, so as to help understand the geo-security risks and opportunities that China is facing on its global development path. As the most of world's land, population and economic activities are concentrated in the eastern hemisphere, especially in Eurasia, Eurasia has always been the central arena for world powers to compete. As the first non-Eurasian hegemonic power in the human history, the United States has always regarded the prevention of regional hegemony on the Eurasian continent as the supreme goal of its national security. From the perspective of the world geographical structure and its dynamic changes, this paper analyzes the geographical advantages of the eastern hemisphere, especially Eurasia, which gave birth to the world powers and human civilization. It also analyzes the influence of the geographical location of the United States on its early rise, the formation of its global strategy under this geographical condition, particularly, and the global military design of the United States based on preventing the emergence of regional hegemony in Eurasia. Finally, It points out that in the strategic game between China and the United States, China, which is located in the eastern edge of Eurasia, has natural geographical advantages.
