2022年半导体还有上涨空间吗

2022年半导体还有上涨空间吗,第1张

有上涨空间。

1、当前,边缘基础设施领域半导体规模尚小,但成长迅速,221预计增速344.1%,222增速预计45.5%。此外,SSD、汽车、数据中心领域是预计222增速最快的领域,预计将分别增长22.%,14.9%,13.2%(据Gartner数据)。

2、221存储增速耀眼,222年仍将延续高增。超级景气周期的延续,看222年半导体将实现第三年连续增长。受汽车、服务器、物联网、5G等数字经济智能应用驱动,半导体市场自219年开启的超级景气周期有望持续三年,根据SEMI收集的各机构对222年全球半导体市场规模及增速预测,222年市场规模预测均值为57亿美元,平均的预测增速为1%,最高预测增速超过15%,来自SIMI。
