国产算力需求持续强劲。

3月13日早盘，AI方向全线逆市上扬，通信、传媒、计算机、电子等板块均逆市走强。概念方面，GPU题材领涨，涨幅超3%。

消息面上，隔夜美股全球AI龙头英伟达股价飙升超7%；另外，国产GPU龙头景嘉微昨日晚间发布公告，公司景宏系列高性能智算模块及整机产品研发成功，将尽快面向市场推广。早盘该股股价一度飙升近20%。

国产GPU龙头发布

重磅AI算力产品

景嘉微在公告中称，景宏系列是公司推出的面向AI训练、AI推理、科学计算等应用领域的高性能智算模块及整机产品，支持INT8、FP16、FP32、FP64等混合精度运算，支持全新的多卡互联技术进行算力扩展，适配国内外主流CPU、操作系统及服务器厂商，能够支持当前主流的计算生态、深度学习框架和算法模型库，大幅缩短用户适配验证周期。

公司表示，本次推出的新产品可以丰富公司面向计算领域的高性能智算产品线，拓宽公司AI推理、AI训练及科学计算等应用领域的市场业务，有利于增强公司核心竞争力，巩固公司在相关领域的市场竞争力与市场占有率，对公司长期发展战略的实施具有推动意义。

方正证券对此事件的评论是：AI里程碑，彰显重大意义。在此消息影响下，早盘该股高开高走，盘中一度逼近20cm涨停。景嘉微堪称本轮AI行情的龙头股，2月5日股价一度低至42.31元，早盘摸高至93.4元，短短22天暴涨121%。

国产算力需求持续强劲

我国重视AI发展，国内产业链有望受益。过去半年，国资委频频发布政策支持AI发展，2月再次强调央企将AI发展列入全局谋划，以运营商为主的央企持续加大算力投入；比如电信已在上海规划布局15000卡（总算力超4500P），其中单池新建国产算力达万卡。以华为昇腾AI为代表的国产AI芯片已具备较强竞争力，昇腾910B算力是英伟达H20（对华特供版3月接受预定）的1倍。国信证券认为，在国产AI芯片有力支持下，我国智算中心部署将得到保障，同时智算中心中的通信设备厂商有望持续受益。

产业发展和政策支持带动国产算力需求持续强劲。随着AI技术进一步发展，通用人工智能及其应用将产生更大算力需求。当前国内智能算力基础设施步入加速建设阶段，包括互联网、政府、运营商等智能算力主要需求方加大相关投入。据不完全统计，目前共有超30个城市建设或规划建设智算中心，已建成并投产的智能算力规模超10EFLOPs（每秒浮点运算次数）。中国电信首次独立招标AI服务器，规模达84亿元；互联网厂商布局自建智算中心，海外及国产AI芯片均供不应求。

国产芯片整体渗透率低，互联网厂商加大国产算力采购力度，有望带来广阔市场空间。

据 IDC 统计，我国2023年上半年AI服务器中采用国产芯片的比例约10%，仍处较低水平。国产芯片主要采购方来自政府、央企等，大多数地方智算中心采用华为昇腾、海光深算、寒武纪思元等国产芯片；中国电信最新AI服务器采购国产比例为 47%。

智能计算芯片下游的最主要客户互联网企业此前使用国产芯片较少，目前正积极探索国产芯片服务器的应用落地。随着国产芯片后续新品发布以及产能提升，互联网厂商大规模采购国产芯片将显著推动其市场占有率提升。

从远期看，根据IDC报告，国内AI服务器市场规模在2027年预计达到164亿美元，五年复合增速26.8%。若未来互联网厂商芯片采购国产化比例提升，带动整体国产芯片占比达到当前运营商采购同等水平，国内国产芯片的AI服务器市场有望达到80亿美元，约为当前市场规模的近10倍。

国产AI产业链细分龙头揭晓

据了解，国产AI产业链主要包括上游芯片/器件领域，A股代表性企业有海光信息、寒武纪、龙芯中科、景嘉微等国产芯片厂商；服务器领域代表企业有神州数码、浪潮信息、紫光股份、中科曙光等。

PCB企业有沪电股份、深南电路、胜宏科技等；交换机领域主要企业有中兴通讯、锐捷网络、菲菱科思等。

光模块领域主要企业有天孚通信、光迅科技、中际旭创等；存储芯片分别为江波龙、佰维存储、兆易创新等；数据中心有润泽科技、润建股份、奥飞数据等。

中游算力网络与平台以电信服务商及互联网企业布局较多，包括三大运营商、云计算厂商、数据提供商、数据安全维护等。

数据宝梳理出各个细分行业的龙头股票，合计共有40只。这些个股年内平均涨幅超过12%，大幅跑赢大盘同期表现。

从成长性角度来看，易华录、中国长城、江波龙、兆易创新、佰维存储等个股机构一致预测今年净利增速均超100%。
