2009年1月，某市政府拿出1亿元财政资金，向特困户、退休市民、残疾人和在校中小学生等8类人员共67万人发放消费券，成人每人200元，学生每人100元。消费券可在400多家商家使用，不但能抵用同等面额的现金，还可以享受程度不同的让利折扣。     

此外，各地还出现了其他形式的消费券。“混用型”消费券的资金来源是地方财政和企业让利，但不能单独使用，必须与一定的现金混用。如游客每花40元现金，可以使用10元旅游消费券。“让利型”消费券的资金来源是企业让利，也与现金按一定比例消费。    

 在当前的经济形势下，有人认为，发行消费券对我国经济将产生积极的影响，也有人认为发行消费券治标不治本，有局限性。    

结合上述材料分析发行消费券对居民、企业和宏观经济的积极影响，并分析发行消费券的局限性。
