The two pillar strategy responds to the fact that we (still) lack a model which encompasses both dimensions, the economic or real and the monetary, in a consistent and robust manner. As long as such a “one-pillar-approach” is unavailable, there is no convincing reason why the ECB should change a strategy which has served it well and allowed it to establish a remarkable track record.
两个支柱战略是对我们（依然）缺乏一个连贯并且坚实地包含了经济或基础部门以及货币因素的模型的事实的一个回应。只要我们还缺乏这样一种“一个支柱的方法”，那么就没有理由要欧洲央行改变其运作得很好、并且使它建立了一个令人瞩目的历程记录的战略。
