--- name: a-share-sector-d0bf6f1012bb description: A股行业研究/板块分析。当用户说"行业研究"、"板块分析"、"行业全景"、"sector overview"、"XX行业怎么样"、"XX板块前景"、"行业对比"、"产业链分析"时触发。通过 cn-stock-data 获取行业内主要公司数据，结合 web 搜索获取行业政策、市场规模、竞争格局等信息，生成结构化行业研究报告。支持券商行业报告风格（formal）和个人行业笔记风格（brief）。不适用于个股深度分析（用 a-share-earnings-analysis）或个股估值对标（用 a-share-comps）。 --- # A股行业研究 (a-share-sector) ## 数据源 ```bash SCRIPTS="$SKILLS_ROOT/cn-stock-data/scripts" # 行业内主要公司行情（市值、PE、PB 等） python "$SCRIPTS/cn_stock_data.py" quote --code [CODE1],[CODE2],... # 各公司财务指标 python "$SCRIPTS/cn_stock_data.py" finance --code [CODE] # 各公司近 1 年日线（行业趋势对比） python "$SCRIPTS/cn_stock_data.py" kline --code [CODE] --freq daily --start [1年前日期] # 北向资金（行业层面资金偏好） python "$SCRIPTS/cn_stock_data.py" north_flow ``` 补充：通过 web 搜索获取行业政策、市场规模、产业链结构、行业新闻。 ## Workflow ### Step 1: 明确研究范围 - 确定行业/板块（用户指定或通过 web 搜索确认申万/中信行业分类） - 选取行业内代表性上市公司（龙头 + 二线，通常 8-15 家） - 选择标准：市值排名靠前、业务代表性强、避免 ST 公司 ### Step 2: 行业全景 通过 web 搜索获取： - 市场规模与增速（TAM、近 3 年 CAGR） - 行业生命周期位置（导入期/成长期/成熟期/衰退期） - 产业链结构（上游原材料 → 中游制造 → 下游应用/消费） - 政策环境（近期重大政策、监管动向） - 行业核心驱动力（需求端 vs 供给端） ### Step 3: 竞争格局 通过 cn-stock-data 获取各公司数据，构建竞争格局表： | 公司 | 市值(亿) | 收入(亿) | 市占率(%) | 毛利率(%) | ROE(%) | 核心优势 | |------|---------|---------|----------|----------|--------|---------| | ... | ... | ... | ... | ... | ... | ... | 分析要点： - 行业集中度（CR3/CR5/HHI） - 竞争壁垒（品牌/规模/技术/渠道/牌照） - 近年格局变化趋势 ### Step 4: 财务对比 从 cn-stock-data 获取并对比行业内公司的关键财务指标： 核心对比表： | 公司 | 营收增速(%) | 净利润增速(%) | 毛利率(%) | 净利率(%) | ROE(%) | 资产负债率(%) | PE(TTM) | PB | |------|-----------|-------------|----------|----------|--------|-------------|---------|-----| | ... | ... | ... | ... | ... | ... | ... | ... | ... | | **行业中位数** | ... | ... | ... | ... | ... | ... | ... | ... | 标注行业中位数，识别优于/弱于中位数的公司。 ### Step 5: 估值分析 - 行业整体估值水平（PE/PB 中位数、分位数） - 估值历史分位（当前处于近 3/5 年的什么位置 — 需 web 搜索） - 个股估值分散度 - 行业 vs 大盘估值溢价/折价 ### Step 6: 输出 根据风格要求输出（默认 formal）。参考 `references/sector-template.md` 中的模板。 ## 风格说明 | 维度 | formal（券商行业报告） | brief（个人行业笔记） | |------|-------------------|-------------------| | 篇幅 | 5-10 页 | 1-2 页 | | 行业全景 | 完整（市场规模+产业链+政策+驱动力） | 精简（1-2 段核心逻辑） | | 竞争格局表 | 完整（10+ 公司，含市占率） | 精简（Top 5 龙头） | | 财务对比 | 10+ 列指标 | 5-6 列核心指标 | | 估值 | 详细（含历史分位） | 当前水平 + 一句判断 | | 投资建议 | 客观描述机会与风险 | 可加个人观点 | | 免责声明 | 需要 | 不需要 | ## 关键规则 1. **数据+逻辑驱动**：所有观点必须有数据支撑，不做空泛定性判断 2. **行业分类标准**：优先使用申万行业分类（一级→二级→三级），web 搜索确认 3. **时效性标注**：标注数据截止日期，行业数据标注来源 4. **不给具体买卖建议**：formal 模式只分析行业趋势和估值位置，不推荐个股 5. **与其他 skill 联动**：报告末尾可建议用 a-share-comps 做更细致的估值对标，或用 a-share-stock-screen 在该行业内筛选 --- Source attribution: aifinlab Original project: https://github.com/aifinlab/FinClaw/blob/9e62862d1412157fa03ffd1f0b74969dcf0ed66c/skills/a-share-sector/SKILL.md License: Apache-2.0 License information: https://www.apache.org/licenses/LICENSE-2.0 Original upstream instructions; downloaded from Dave AI. ## Upstream license notice Apache License Version 2.0, January 2004 http://www.apache.org/licenses/ TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 1.
