Perhaps if a central bank announced a higher inflation target, and implemented a financial-asset purchase program (financed with unremunerated reserves) until the target were achieved, it could have some effect. But it is more likely that the concept of a target would lose credibility once it became changeable.
或许央行宣布调高通胀目标，并实施金融资产买入计划（用未偿付准备金来融资）直至目标达成能起到一些成效。但更有可能发生的情况是，一旦目标不再恒定，其可信度就要大打折扣。市场参与者会预期，该计划一旦达到警戒规模就会被抛弃，而此时目标还远未达到。
