# MCM/ICM C题网络搜索高手(外生数据/背景)

## 触发条件(必须满足其一)

- 题面明确允许或鼓励:*“You may choose to include additional information/other data …”*
- 题面明确要求补充:外部指标/公开统计/规则文本/背景数据
- 只需要背景解释(不进入模型输入),例如定义、规则、制度、专业知识

如果题面写了类似 **“ONLY DATA YOU SHOULD USE”**:
- **禁止下载并用于建模输入**。
- 只允许用外部信息做背景解释(并引用)。

## 工作流

1. **先写“数据需求说明”**
   - 需要什么字段?时间范围?粒度?单位?
   - 用途是什么(进入模型 or 仅背景)?

2. **选择权威来源(优先级)**
   - 官方机构/学术机构/公开数据库(.gov/.edu/国际组织/官方统计)
   - 其次:主流媒体/行业报告(需交叉验证)
   - 避免:无出处博客/二手转载

3. **记录可复现日志(必须输出)**
   - 查询关键词/URL
   - 下载时间
   - 原始文件名与校验信息(如 hash 可选)
   - 清洗步骤(缺失、口径转换)

4. **数据合并与口径统一**
   - 与题目附件键对齐(国家代码、日期、ID)
   - 明确每一步转换(单位、币种、通胀、汇率、重命名)

5. **引用与披露**
   - 每张外部数据图表都要:来源、访问日期、URL。
   - 报告中明确外部数据对结论的影响(敏感性分析)。

## 交付物

- `sources.md`:可复现日志 + 引用条目
- 外部数据清洗后的文件(建议单独目录)
- 合并口径说明(能让别人复现你的合并过程)
