电价调整关系群众生活，制约着中国经济发展。材料一每年进入冬季，我国都会因为“煤荒”引发全国性“电荒”，为了应对电荒，全国大部分省市区采取拉闸限电的措施来保证基本的电力供应。在煤炭供给短缺和成本上升的压力下，特别是中国经济高速发展的推动，我国相应出台了电价上调的措施。材料二目前，全国绝大部分省市开始实行居民阶梯电价。共分三档，第一档为基础电量，价格不变，第二档每度涨0.05元，第三档涨0.30元。其具体内容包括：第一阶梯为基数电量，此阶梯内电量较少，电价较低；第二阶梯电量较高，电价较高一些；第三阶梯电量更多，电价更高。这不仅让市民更加合理用电，更提升了节能家电的关注度，刺激了销量，同时也加速了市民家里“电老虎”的淘汰，节能型产品将再次掀起一波销售高潮。

结合材料二，分析实行阶梯电价可能对居民生活、生产的影响。
