RADAR评估166国AI服务可描述性与可触达性，发现描述优于触达且差距不随财富缩小，提出改进网络存在度以提升智能体可操作性的具体议程。
AI 中文摘要
政府越来越多地通过AI系统而非网站来接待公民。RADAR（面向AI发现与智能体触达的准备度）衡量该系统是否有效，覆盖166个国家，并基于两项任务：聊天机器人能否就公共服务提供正确、有官方来源、针对特定国家的回答（信息可读性），以及自动化智能体能否触达该服务并对其采取行动（智能体可操作性）。核心发现是，AI描述公共服务的能力远优于其触达服务的能力。在全部166个国家中，信息可读性得分均超过RADAR相应衡量标准下的平均智能体可操作性得分，且这一差距并不随国家财富而缩小。收入和语言仅能解释部分模式，若干政府的表现远好于或差于其资源所预测的水平。这两种失败具有不同的相关因素和不同的解决方案。AI能否描述一项服务与该国主要行政语言在网络规模语料库中的代表性相关，这是政府无法迅速改变的。智能体能否触达服务则与该国的国家网络存在度相关，而政府现在就可以改变这一点。传统的数字政府排名完全忽略了第二个问题。RADAR使任何收入水平的政府都能看到这一问题，并提供具体的解决议程，从而使公共服务不仅被AI描述，而且能通过AI实际触达。
英文摘要
Governments increasingly meet citizens through an AI system rather than a website. RADAR (Readiness for AI Discovery and Agentic Reach) measures whether that system works, across 166 countries and on two tasks: whether a chatbot can give a correct, officially sourced, country-specific answer about a public service (informational legibility), and whether an automated agent can reach the service to act on it (agent operability). The central finding is that AI can describe public services far better than it can reach them. In every one of the 166 countries, informational legibility scores exceed average agent operability scores under RADAR's respective measures, and the gap does not shrink with national wealth. Income and language explain only part of the pattern, and several governments perform far better or worse than their resources predict. The two failures have different correlates and different fixes. Whether AI can describe a service is associated with how well a country's main administrative language is represented in web-scale corpora, which a government cannot change quickly. Whether an agent can reach it is associated with the country's national web presence, which a government can change now. Traditional digital-government rankings miss the second problem entirely. RADAR lets governments at any income level see it and offers a concrete agenda to fix it, so that public services are not only described by AI but actually reachable through it.
