芯片短缺,本田停产
半导体芯闻· 2025-12-18 10:24
本田此前曾表示预计从11月底开始恢复正常生产,但此次停产无疑是一次挫折。最新的停产措施 表明,供应限制问题依然存在,这使得恢复产量和稳定库存的努力更加复杂。 然而,这些停产也可能促使人们重新审视潜在的需求状况。在亚洲部分地区,由于借贷成本上升、 消费者支出谨慎以及经济增长势头不平衡,汽车需求有所疲软。在此背景下,暂时停产可以起到双 重作用:既能帮助制造商管理库存,又能使产量更贴近销售趋势。虽然本田并未明确指出需求疲 软,但持续存在的供应问题与更具挑战性的需求环境之间的重叠表明,此次停产可能反映的是更广 泛的调整,而不仅仅是物流中断。 该消息令投资者情绪承压,媒体报道后,本田股价在东京交易时段下跌约1.5%。市场反应反映 出,人们担心持续的供应限制——加上需求疲软——可能会在新的一年里继续抑制盈利增长势头。 中国市场对本田而言依然至关重要,无论从销量还是生产规模来看都是如此,因此其合资工厂的停 产尤其引人注目。更广泛地说,这一事件凸显了全球汽车制造商即便在通过优先生产高利润车型和 调整生产组合来适应市场变化的同时,仍然面临着供应瓶颈和周期性需求风险的双重挑战。 针对多个地区工厂临时停产的情况,本田方面此前回应称 ...
