The problem of too big to fail is not new – the phrase was first used in the United States in the 1980s. It refers to any firm – usually in the financial sector – whose failure would have major negative spillover effects for the rest of the financial system and for the real (non-financial) part of the economy.
太大而不能倒问题并不新鲜——这个词首次在美国使用是在20世纪80年代。它可以用于任何企业——通常是金融企业——只要其倒闭会对金融体系以及实体（非金融）经济带来巨大的消极溢出效应。
