算力体现网络价值，AIDC 成为基建先锋。IDC 利用已有的互联网通信线路和带宽资源，建立标准化的电信专业级机房环境，为企业和政府提供服务器托管、租用以及相关增值等方面的全方位服务。我国 IDC 行业快速发展，数据中心机架总规模由 2019 年的 315 万架增长至 2023 年的 810 万架，但也造成了短期市场供给过剩的问题，其中一线城市机房上架率仍处在高位，但中西部以及东北地区算力需求有限，机房上架率较低，在供需失衡的背景下，部分公司 IDC 租金出现不同幅度下滑。

我们在 2025 年 2 月 19 日发布的《白银行业深度Ⅰ：全球白银供给将进入刚性低速增长新阶段》中，对白银行业的供给进行了系统性的梳理及分析，发现2024-2027年全球白银总供应将维持较低增速，全球白银年度供应量将由31915吨增长至33039吨，期间 CAGR 或为 1.2%，主因回收银产量的提升短期内难以抵消矿端供应增速缓慢的影响。本文我们将从白银的需求角度对全球白银消费的韧性、弹性及变化趋势进行分拆追踪，从而对全球白银供需平衡状态做出有效拟合。通过供需的定性及定量分析，我们发现全球白银的供需状态将延续偏紧状态，供需缺口在 2025-2027 年间或持续放大。

• Autonomous vehicle makers are working hard to address the issue of autonomous vehicle safety when they are deployed on public roads. These players believe that autonomous vehicles will be far safer drivers than human drivers. This standard necessitates a large increase in existing testing installations.

A drone navigation system is an equipment designed to control and guide unmanned aerial vehicles (UAVs) during their flight operations. It encompasses various components and algorithms that enable the drone to autonomously navigate through its surroundings, avoiding obstacles and efficiently reaching its destination. The system typically includes a Global Positioning System (GPS) for accurate positioning, sensors such as accelerometers and gyroscopes for stability and orientation, and advanced flight control software. It also incorporates obstacle detection and avoidance mechanisms, mapping capabilities, and communication protocols to ensure seamless operation and safe navigation. The drone navigation system plays a crucial role in enabling autonomous and efficient drone operations across various industries and applications.

The global e-cigarette market is defined by the industry engaged in the production, distribution, and sale of electronic cigarettes, also known as e-cigarettes or vapes. These are battery-powered devices that deliver nicotine, flavorings, and other chemicals to users through an aerosol, commonly referred to as vapor, without involving the combustion that characterizes traditional tobacco products.
