Digital video content is primarily accessed through two sources, namely OTT and Pay TV. These platforms are major sources of entertainment for users worldwide. Pay TV is a subscription-based TV service that delivers digital video content through analog, digital, and satellite connections. The OTT industry includes third-party service providers that deliver video content to users through the Internet.

A document scanner is a device that scans a paper document and converts it into a digital format, which can be stored on digital devices. The process of document scanning is also referred to as document imaging.

The global education personal computer (PC) and tablet market is the part of the technology industry that focuses on providing personal computers (PCs) and tablets specifically designed for use in educational settings, such as schools, colleges, universities, and other learning environments. These devices are tailored to meet the unique requirements of educational institutions and students, including durability, compatibility with educational software, ease of use, and affordability.

Drones are pilotless aircraft or flying robots, which are also referred to as UAVs. Drones fly autonomously or are controlled by an onboard computer. They can also be operated using a remote control from the ground. Commercial drones are drones that are used in commercial sectors such as industrial, terrestrial imagery and mapping precision agriculture, inspection and monitoring, and others.

Edge computing is the practice of processing data near the logical extremes (edge) of the network (i.e., near the source where data is generated). It depends on distributed computing device nodes for data processing and analysis instead of a centralized data-processing warehouse in a cloud computing environment.

The market by value in this report is defined as the revenues that enterprises gain from goods and/or services sold within the specified market and geography.

检测服务伴生于半导体产业的全链条，胜科纳米 2023 年主营营收中 49.0%来自芯片设计环节、20.8%来自晶圆代工、8.0%来自于材料与设备；且主要服务于客户研发环节，在胜科营收中占比 80%-90%。在中美贸易摩擦加剧的背景下，实现产业链自主可控的需求愈加迫切；长江行 业分类中半导体细分领域的整体研发费用率为 9.1%（2024 年前三季度），仍有较大提升潜力。我们测算 2025 年国内半导体检测市场规模将达到约 68.5 亿元，考虑到先进制程、第三代半导 体、5G、高性能计算（HPC）、智能汽车、AI 等新兴领域的需求逐渐释放，预计 2030 年市场规模可达到约 139 亿元，“十五五”期间市场规模复合增速达到 15.2%。

从 3 月以来，中美关税持续博弈，在此背景下，国内半导体产业链自主可控预期持续强化；同时，部分厂商发布 25Q1 业绩预告，细分环节边际复苏趋势明 显。建议关注受益于国产替代进程的模拟/代工/设备等板块、景气周期边际复苏叠加创新加速的存储/SoC 板块、受益于国内 AI 生态发展的国产算力芯片等环 节，同时建议关注各科创指数和半导体指数核心成分股。

著名的“301调查”是基于美国1974年贸易法第301条，是美国政府为平衡进出口贸易的顺逆差，透过美国国会立法授权美国总统实 施保护措施，以避免国内产业遭受国外竞争压力影响。美国政府往往会提高关税以作为对贸易对手国的报复性惩罚。在此基础上又衍 生出聚焦知识产权的“特别301条款”和不针对特定产品而针对国家的“超级301条款”

行业要闻及简评： 1）4月2日，美国总统特朗普在白宫签署两项关于所谓“对等关税”的行政令，宣布美国对所有贸易 伙伴设立10%的“最低基准关税”，并对多个贸易伙伴征收更高关税；2）杜邦中国涉嫌垄断被国家市场监督管理总局立 案调查 ； 3 ） 2025年3月31日，2025雷神科技AI智能眼镜产品正式发布，产品搭载了高通AR1芯片和索尼光学镜头，支持 1080P视频录制和沉浸式音效，重量仅39g，深度整合火山引擎，并且接入DeepSeek架构。
