当前美国次级抵押贷款危机引发的全球金融海啸,对世界经济产生了巨大冲击。在当今经济全球化、一体化背景下,国际上也非常重视“外部冲击”的研究,这种外部冲击既源于经济方面的因素,如贸易冲突、能源危机、粮食危机以及利率和汇率波动,又来自于非经济方面事件如技术革命、自然灾难、恐怖袭击以及政治政策的变化,而且这种外部冲击既带来正效应,也有负效应。对待外部冲击,应该主动应变,在外部冲击中寻求平衡与发展。 The current global financial tsunami triggered by the U.S. subprime mortgage crisis has had a huge impact on the world economy. In the context of economic globalization and integration, the international community also attaches great importance to the study of “external shocks” that originate from economic factors such as trade conflicts, energy crises, food crises and interest rates and exchange rates Volatility, in turn, comes from non-economic events such as technological revolutions, natural disasters, terrorist attacks and changes in political policies that have both positive and negative effects. To deal with external shocks, we should take the initiative to seek for balance and development in external shocks.
