(Xinhua/Sun Suying)Beijing's blue skies have become a visible sign of the city's progress in tackling air pollution, and behind that progress, digital technologies are playing an increasingly important role.
In 2025, Beijing recorded 311 days with good air quality and only one heavily polluted day, compared with 58 heavily polluted days in 2013, when the city officially began releasing PM2.5 monitoring data. The annual average PM2.5 concentration, a key indicator of air quality, fell from 89.5 micrograms per cubic meter in 2013 to 27 micrograms per cubic meter in 2025, a decline of nearly 70 percent.
The progress has drawn international attention. The United Nations Environment Programme has highlighted Beijing's experience in improving air quality as a model for other cities.
According to experts at the Beijing Municipal Ecological and Environmental Monitoring Center, the cleaner air is the result of a comprehensive system integrating environmental monitoring, scientific analysis, policymaking, regional cooperation and law enforcement -- with digital technologies now woven into every link of that chain.
MORE TARGETED APPROACH
Effective governance begins with accurate monitoring. Beijing has established a multi-level air-quality monitoring network. Figures show 35 standard monitoring stations across the city continuously measure six major pollutants, while more than 1,000 compact sensors deployed across communities and townships provide more detailed information on local air-quality variations.
The monitoring system was gradually built by the Beijing Municipal Ecological and Environmental Monitoring Center, one of China's earliest ecological and environmental monitoring institutions, responsible for monitoring Beijing's air, water, noise, soil environments and ecosystems.
The center has developed an analytical system that can identify around 125 components of PM2.5, covering most of its composition and helping researchers trace pollution sources.
"Source analysis helps us identify the major contributors to pollution at different stages, providing a scientific basis for policymakers to target key emission sources," said Li Yunting, technical director at the center.
Coordinated by the Beijing Municipal Ecology and Environment Bureau, the center has conducted four rounds of PM2.5 source analysis studies with other institutions, with results released in 2014, 2018, 2021 and 2025.
The latest analysis showed that regional transport contributed 57 percent of Beijing's PM2.5 pollution. Among local sources that accounted for the remaining 43 percent, vehicle emissions and residential sources represented the largest share of pollution, a distinctive characteristic of a major international metropolis.
The monitoring results have provided scientific support for a series of pollution-control measures. For example, Beijing has promoted new-energy vehicles to reduce transport emissions and adopted advanced techniques, including air-supported membrane structures, to control dust emissions. Meanwhile, coal combustion pollution, once a major contributor, has almost been eliminated and is no longer listed among the main sources, reflecting broader national efforts to reduce coal consumption, promote clean energy and upgrade heavily polluting industries.
With PM2.5 concentrations now at relatively low levels, further gains in air quality will depend on more targeted, science-driven approaches.

SMARTER ENVIRONMENTAL GOVERNANCE
Beyond monitoring pollution, Beijing has built a data-driven environmental governance system that links monitoring, regulation and enforcement in a closed loop from detection to action and follow-up evaluation.
Developed by the center and known as the innovative regulation-monitoring-inspection linkage model, the system integrates artificial intelligence, the Internet of Things, satellite remote sensing and vehicle-mounted monitoring technologies to pull together environmental data from multiple sources onto a unified platform.
"The system brings information that was once scattered across different departments onto a single platform," said Zhang Likun, director of the smart system division at the center, adding that this enables off-site enforcement and joint cross-sector actions involving housing, water resources and transportation, significantly improving the efficiency and precision of environmental management.
Using more than 30 intelligent algorithms, the platform automatically analyzes data and identifies potential pollution risks, based on which monitoring staff identify the most pressing problems and forward them to enforcement departments.
The approach has already drawn international attention. Clean Air Asia, an international nongovernmental organization focused on improving air quality across Asia, featured the system as a representative case study in its "China Air 2025" report. The model was also presented at the 2026 Better Air Quality Conference and recognized with the Certificate for Clean Air Best Practice Sharing.
China has integrated ecological conservation into its modernization drive. As the country speeds up efforts under the Beautiful China Initiative, Beijing's experience demonstrates how technology can support more precise, coordinated and sustainable environmental governance.

　　本周，金融市场将迎来经济数据、财报和地缘局势等一系列重磅事件的扰动。其中，美联储主席凯文·沃什将于8月28日（周五）在杰克逊霍尔全球央行年会上发表讲话。美联储最青睐的通胀指标—7月PCE物价指数将于8月26日（周三）公布，或将直接影响市场对美联储的加息预期。尽管美联储9月加息的紧迫性有所降低，但目前市场仍预期美联储可能会在2026年年底前进行一次加息。　　另外，美股财报季也将迎来重头戏，全球“AI总龙头”英伟达将于北京时间8月27日凌晨披露财报，其业绩指引被视为AI资本开支周期的“终极验证”，全球“AI交易”可能会遭遇剧烈波动。　　沃什本周将发表重要讲话　　根据日程安排，2026年杰克逊霍尔全球央行年会将于8月27日至29日在美国怀俄明州举行，会议主题为“金融创新：对支付与政策的影响”。

B | 　　沃什将于北京时间8月28日晚上10点在年会上发表重要讲话。沃什此前表示，他希望利用这次演讲来界定美联储面临的“重大问题”——包括对通胀目标、生产力、人口结构变化以及全球经济冲击的担忧。　　投资者期待沃什阐明美联储未来将如何应对顽固通胀，但目前尚不确定他是否会给出明确表态。

C | 迄今为止，沃什一直回避给出任何前瞻性政策指引。　　道明证券策略师表示，从理念上，沃什本就不愿给出政策指引，预计沃什不会改变其解读经济前景的表态方式。市场将寻找有关其政策反应函数的线索，同时期待他重申美联储对抗通胀的立场。　　彭博经济学家预计，沃什更可能重点讨论其美联储改革的理念框架，强调前瞻指引可能降低政策灵活性，并干扰市场信号。　　而在此之前，美国国债市场遭遇猛烈抛售，美国30年期国债收益率一度升至5.337%，创下2007年6月以来新高。随后，美国财政部紧急宣布，将10年至30年期美债的流动性支持回购操作规模至少提高一倍。　　有分析人士指出，近期美债抛售潮的原因之一，是沃什上任后坚决不给货币政策的前瞻指引，甚至还扬言“美债收益率上升已经帮美联储完成部分工作”。　　在全球央行年会召开前，美联储“最青睐的通胀指标”美国7月PCE通胀数据将于北京时间8月26日20:30公布，若该数据超出市场预期，市场对9月美联储的加息预期或将再度升温，进而引发美债收益率与全球风险资产联动波动。此外，美国二季度实际GDP修正值也将于当天20:30公布。　　财报季的重头戏　　美股财报方面，根据日程安排，英伟达将于北京时间8月27日凌晨发布截至7月的季度财报，全球AI资本开支周期将迎来“终极验证”，或将引发市场巨震。　　据杰富瑞最新发布的报告，预计英伟达本财季收入将达到950亿美元，高于市场一致预期的约919亿美元；下一财季收入指引有望达到1080亿美元，也高于市场预期的约1037亿美元。　　另有分析指出，真正决定英伟达股价弹性的是三个更长期的问题：Rubin能否顺利接棒Blackwell、AI需求是否仍显著大于供给，以及英伟达为锁定未来需求需要承担多大的融资和资产负债表责任。

D | 　　杰富瑞认为，英伟达Rubin的爬坡速度可能显著快于Blackwell初期。

E | 原因在于Rubin延续72-GPU Oberon NVL72机架形态，能够复用GB200、GB300积累下来的液冷数据中心部署和制造基础。　　摩根士丹利指出，融资、市场份额和毛利率是投资者当前最关注的三大争议点。英伟达管理层大概率会强调这些结构有助于加速AI基础设施建设，但投资者需要看到更清晰的会计披露，包括或有义务、租赁和电力支付支持、残值承诺等细节。

F | 　　另外，中东局势依然是重要且不可控的场外因素。

G | 　　根据此前预告，美国财长贝森特将于当地时间周一美股盘中（北京时间周二凌晨）举行新闻发布会，披露美国对伊朗实施“前所未有的经济孤立”措施的细节。　　目前市场尚不理解美国如何在军事打击都未能奏效的情况下，通过加码经济制裁逼迫伊朗妥协。　　伊朗最高国家安全委员会秘书雷扎伊8月22日公开表示，任何参与对伊朗实施经济限制的国家，都被伊朗视为敌人。
