受美国次贷危机冲击,目前发达经济体经济增长速度明显放缓。与此同时,新兴市场经济体表现出较好的抵御外部冲击能力,成为推动世界经济增长的重要力量。一些美国经济学家认为,随着新兴市场经济体的崛起,世界经济格局正在发生深刻变化。 Affected by the subprime mortgage crisis in the United States, the economic growth rate of the developed economies has obviously slowed down.

Some U.S. economists think that with the rise of emerging market economies, the world economic situation is undergoing profound changes.
