摘要

人工智能搜索引擎（如ChatGPT）兴起，用户无需访问原始网站即可获取信息，导致网络流量普遍下滑。整体流量减少15%，部分领域受损尤甚：科教类网站下降10%，医疗健康类骤减31%，旅游平台Tripadvisor流失33%，健康资讯站WebMD更是腰斩50%。访客锐减直接冲击广告收益，内容创作与网络社区生存堪忧。具体表现为：维基百科编辑贡献减少，技术问答社区Stack Overflow提问量走低，社交论坛Reddit股价下挫。为求生存，网络转向付费墙、邮件订阅、社交媒体及音视频内容等多元路径。业界呼吁建立新型商业模式，建议方案含AI爬虫按量计费机制与内容溯源体系。若优质内容持续流失，恐将陷入公地悲剧困境，届时需监管力量介入。值得警惕的是，依赖外部数据训练的AI企业，一旦内容源头枯竭，自身发展亦将受阻。

AI-powered search engines (e.g., ChatGPT) reduce need to visit websites, cutting traffic. Web traffic down 15% overall; specific sites hit harder: science/education -10%, health -31%, Tripadvisor -33%, WebMD -50%. Loss of visitors means lost ad revenue, endangering content creation and online communities. Examples: Wikipedia contributions drop, Stack Overflow questions decline, Reddit share price falls. Web adapts with paywalls, email newsletters, social media, audio/video content. Need new business model: proposals include pay-as-you-crawl for AI bots and attribution systems. Risk of tragedy of the commons if web content exhausts; regulators may need to step in. AI companies reliant on external content could suffer if creation stops.
