2007年下半年,美国次贷危机不期而至,受其冲击,世界经济增长趋势明显放缓,各种不确定性增加,国际竞争愈益激烈。次贷危机使美国正在经历一个新的经济周期最为关键的阶段:经济膨胀、繁荣之后的恐慌与衰退。而且,这种恐慌与衰退还在难以抑制地向世界上更多的地方蔓延。 In the second half of 2007, the subprime mortgage crisis in the United States came unexpectedly. Under the impact of the subprime mortgage crisis, the world economic growth trend has obviously slowed down, all kinds of uncertainties have increased, and international competition has become increasingly fierce. The subprime mortgage crisis has left the United States undergoing the most crucial phase of a new economic cycle: economic expansion, panic and recession after prosperity. Moreover, the panic and the recession are still unquenchably spreading to more places in the world.
