据追风交易台，伯恩斯坦Chad Dillard领导的分析师团队在最新研报中指出，当美国预计2030年将面临50吉瓦电力供应缺口时，一场覆盖全球电 力行业的超级周期已全面拉开序幕。但资本市场的反应暗藏明显的认知偏差：过去12个月，卡特彼勒、康明斯等发电端企业股票相对标普500 指数暴涨80%，而伊顿、施耐德、ABB等聚焦配电及电力管理的企业股价却逆势下跌10%，显著跑输大盘。 这场估值分化折射出市场对电力超级周期的理解局限。多数投资者执着于"建更多电厂"的蛮力扩张逻辑，却忽略了破解电力短缺的最优解：在 不增加发电容量的前提下，通过技术创新提升电力效率。 电力超级周期的核心矛盾，已从 "如何增加发电产能" 转向 "如何提升电力使用效率"。 伯恩斯坦研报指出，800伏数据中心架构和765千伏输电线路这两项高电压技术，每项都能将电力效率提升高达5%。这一数字看似温和，却能 在不新增发电容量的情况下，有效填补供需缺口。 随着电力周期从"产能扩张"的第一阶段进入"效率提升"的第二阶段，此前被低估的配电及电力管理企业有望收复失地，重塑市场格局。 需求爆发与供给瓶颈下的认知偏差 电力超级周期的驱动逻辑，本质是需求爆炸与供给瓶 ...
