9月预购季收官（Day4）， 苹果iPho ne 17系列 交出了一份"交付周期拉长"的成绩单。 根 据高盛9月15日发布的研报，无论是全球市场还是中国、美国等核心区域，iPhone 17的交付 周期普遍比去年的iPhone16更长。 基础版（base）周期多8天，Pro Max更是多8天，就连定位中端的Air型号（替代去年的 Plus）也多等3天。更值得关注的是，中国大陆市场的交付周期领跑全球，base/Pro/Pro Max型号要等足足5周，而iPhone Air还因eSIM政策延迟上市。 对普通消费者来说，等手机的时间变长或许只是"小烦恼"；但对投资者、产业链厂商乃至整个 消费电子行业而言，这组数据藏着三重关键信号：需求是否真的"爆棚"？供应链能否接住增量 订单？让我们来抽丝剥茧现象下的本质。 01 交付周期拉长：是需求"真旺"还是供给"拖后腿"？ 要判断交付周期拉长的原因，最直接的方法就是"对比需求和供给"。 需求端：周期拉长不是"首日狂欢"，而是"持续放量" 高盛特意追踪了预购Day1（9月12日）和Day4（9月15日）的周期变化，结果很能说明问 题： Day1数据：全球范围内，iPhone 17 ...
