The current situation has its roots in a series of crises over the last decade that were caused by excessive investment, particularly the bursting of the Japanese asset bubble, crises in emerging Asia and Latin America, and the collapse of the IT bubble in industrial countries. Investment has fallen off sharply since, and has since staged only a very cautious recovery.
目前状况的根源在于过去十年里由过度投资引发的一系列危机，特别是日本资产泡沫的破灭、亚洲和拉美新兴市场的危机、以及工业国家IT泡沫的破灭。从那以后，投资衰退了，而且复苏非常缓慢。
