Beijing E-Town emerges as AI investment hotspot_我的网站

一 |

跑完一场马拉松，打开社交媒体，满屏都是“破三成功！”你低头看看自己的成绩——4小时20分。

二 | 明明跑完了42.195公里，却觉得成绩"不够好"，甚至有些丢人，不好意思发朋友圈。 (ECNS) -- The Beijing Economic-Technological Development Area, also known as Beijing E-Town, has emerged as a major destination for AI investment, with several companies securing funding worth billions of yuan this year. In the first half of the year, eight leading AI companies based in Beijing E-Town raised more than 15 billion yuan ($2.1 billion), spanning fields including world models, AI chips and AI-generated content, the official data released by the E-Town shows. AI video and world-model developer AIsphere recently completed its Series C funding round, raising a total of 2.98 billion yuan ($414 million). The funding will support the development of its video-generation foundation models, real-time world models and industrial applications, according to news released by the E-Town. Automotive chipmaker SemiDrive Technology completed a Series C funding round worth nearly $100 million in May. World-model company VAST secured more than 1 billion yuan ($139 million) in strategic investment in July, bringing the total raised in its Series A funding rounds to nearly 3 billion yuan ($417 million). During the 14th Five-Year Plan period (2021–2025), Beijing E-Town established government-guided funds totaling about 20 billion yuan ($2.8 billion). It has also recently launched four new industrial investment funds with a combined value of 20 billion yuan, including an 8-billion-yuan fund focused on AI and integrated circuits. Beijing E-Town said during the 15th Five-Year Plan period (2026–2030) it will continue to expand support for AI development across the entire industry chain, from computing infrastructure and algorithms to models and applications. （By Helen Mo, intern Liu Shuangjing) 。

三 | 就算有跑友问你成绩，你只是敷衍一句“安全完赛”。这种焦虑，你熟悉吗？其实"破三"从来不是大多数人的赛道，它只是极少数跑友的竞速游戏。数据不会骗人2025年中国田径协会发布的数据显示：全国马拉松跑进3小时的跑友一共只有21997人。同年全马完赛总人次是74.09万。算下来，破三的比例不到3%。换个更扎心的说法：每100个能跑完全马的人里，只有不到3个人能跑进3小时。而这100个人，已经是十几亿人里敢于站上起跑线的极少数了。如果把所有跑过步的人都算上，男性破三跑者占整个跑步人群的比例大约只有0.5%，女性更是低到0.05%。一千个跑步的人里，只有5个男性能破三；一万个女跑者里，只有5个能做到。再看看平均成绩：2025年全马总体平均完赛成绩是4小时06分。大多数人的真实水平，离3小时还差着一个小时。其实能跑四个多小时，不算慢，属于正常的水平。

四 | 破三到底有多难？很多跑友觉得："我只要足够努力，早晚能破三。"但现实没那么简单。破三意味着要以平均每公里4分15秒的速度，连续跑42.195公里。这个配速，很多人跑3公里都坚持不下来。有统计显示，70%的破三跑者月跑量在300公里以上。普通跑友月跑量100-200公里已经算勤奋了，300公里意味着每天平均跑10公里、几乎不休息。如果没有任何专业基础，普通跑者想破三，通常需要1到3年的系统训练。过了45岁，身体恢复能力下降，破三难度成倍增加。如果你没有破三，不是你不够努力，是这件事本来就不简单。

五 | 焦虑从哪来？为什么现在人人都焦虑"破三"？因为社交媒体上晒出来的，永远是那些"大神"——北马4700人破三、无锡马破三率15.5%……但你忽略了一个事实：这些马拉松在挑选参赛选手的时候，基本都是破三优先！就算这样，北马4700人破三，占比也不过14.7%。站在北马赛道上的3.2万人里，依然有超过85%的人没跑进3小时。而那些跑4小时、5小时的人，他们不发朋友圈，不晒成绩。

六 | 沉默的大多数被忽略了。于是你看到满屏的"破三"，却看不到背后更多没破三的人。

七 | 这种错觉，让你觉得"人人都在破三，只有我不行"。写在最后回到最开始的问题：你为什么要跑步？是为了健康？是为了快乐？还是仅仅为了一个"3小时"的数字？如果跑步让你焦虑、让你觉得自己"不够好"，那它已经背离了初衷。跑不进3小时又怎样？你依然完成了42.195公里，依然比那些从未站上起跑线的人勇敢得多。
