国际金融危机以来，美国兴衰问题又一次成为热门的全球辩论议题。本文分析了这场辩论中不同观点背后的政治动机，指出美国经济复苏能力、巧实力以及中国等新兴大国的崛起是这场辩论中的三个新议题，美国本身的内外战略调整是其未来国力兴衰的决定性因素。新兴大国力量和地位上升造成了美国地位的相对下降，但美国本身实力将继续增长，并在20～30年内继续保持唯一超级大国的地位。
The decline or renewal of U.S.power has again been a hot discourse in the world stage since the global financial crisis. This article analyzes the political motivations that lead to opposing conclusions. Three themes-America’s economic recovery，smart power，and the rise of emerging powers-are new in this round of debate. America’s adjustments in its development and international strategies are a decisive factor in shaping its future destiny. While the emerging powers like China have resulted in the relative weakening of U.S. global influence，its power will continue to grow and its international primacy will be maintained for at least two to three decades to come.
