## Purpose

Create comprehensive **A股行业/板块深度报告** covering market dynamics, competitive positioning, regulatory environment, key players, trading multiples, and thematic trends.

## Data Sources

### Primary: iFind MCP (Tier-1 付费) / AkShare MCP (Tier-2 免费备选)

```python
get_industry_stocks(industry="白酒")     → 板块成分股
get_quote(ticker)                        → 个股行情、估值
get_financials(ticker, "income")         → 财务数据对比
get_index_data("000001")                 → 大盘基准
# News (china-news MCP — separate server)
get_stock_news(ticker="{{TICKER}}")          → 行业新闻
get_market_overview()                    → 涨幅榜/成交额榜
```

### Secondary Sources

| Source | Use |
|--------|-----|
| 东方财富行业板块 | Industry classification, sector indices |
| 巨潮资讯 | Company filings for competitive analysis |
| 国家统计局 / 海关总署 | Macro data (industry output, trade) |
| 行业协会 (中汽协, 硅业分会, etc.) | Sector-specific statistics |
| Wind / Choice / 同花顺 | Comprehensive sector data |
| 券商研报 | Analyst consensus and frameworks |

## Workflow

### Step 1: Define Scope & Angle

**Clarify:**
- Sector / industry focus (e.g., 白酒, 半导体, 新能源汽车)
- Angle (e.g., investment theme, competitive analysis, turnaround story)
- Geographic scope (A-share only, or include HK-listed / US-listed Chinese)
- Time horizon (cyclical analysis, secular trends, near-term trade)

### Step 2: Market Size & Structure

**Industry overview:**

| Metric | Data | Source |
|--------|------|--------|
| Total market size | 市场规模 (亿元/亿元) | 国家统计局, 行业协会 |
| Growth rate | 同比增速 / CAGR | Historical data |
| Market share | CR5, CR10 concentration | Company filings |
| Penetration rate | For new industries | Industry reports |
| Export/import | 进出口数据 | 海关总署 |

**A-share representation:**
- Number of listed companies in sector
- Total market cap (总市值 / 流通市值)
- Average PE / PB multiples
- Liquidity (average daily turnover)

### Step 3: Competitive Landscape

**Peer mapping:**

```python
# Get all stocks in an industry
get_industry_stocks(industry="白酒")
```

**For each major player, pull:**
```python
get_quote(ticker)           → Price, market cap, multiples
get_financials(ticker)      → Revenue, margins, growth
get_stock_info(ticker)      → Business description
```

**Competitive analysis table:**

| Company | Ticker | Market Cap (亿) | Revenue (亿) | YoY Growth | Gross Margin | Net Margin | PE (TTM) | Market Share |
|---------|--------|----------------|-------------|------------|-------------|------------|----------|-------------|
| | | | | | | | | |

**Competitive positioning:**
- Market share trends (gaining or losing)
- Product positioning (premium, mid-tier, mass market)
- Geographic footprint (national vs regional)
- Distribution strength (渠道能力)
- Brand equity (品牌力)

### Step 4: Trading Multiples & Valuation

**Sector multiples:**

| Metric | Current | 1Y High | 1Y Low | 5Y Average | Historical High | Historical Low |
|--------|---------|---------|--------|------------|----------------|----------------|
| Average PE | | | | | | |
| Average PB | | | | | | |
| Average PS | | | | | | |
| EV/EBITDA | | | | | | |

**Multiple dispersion:**
- Premium names (high multiple vs sector)
- Value names (low multiple vs sector)
- Historical range and where we are in cycle

### Step 5: Policy Environment

**China-specific policy analysis:**

| Policy Area | Current Status | Impact |
|-------------|---------------|--------|
| 产业政策 | 支持/限制/中性 | Direct sector impact |
| 环保政策 | 双碳目标 | Cost structure impact |
| 监管政策 | 集采/反垄断 | Margin / market share impact |
| 补贴政策 | 新能源/半导体补贴 | Competitiveness impact |
| 货币政策 | 宽松/中性/紧缩 | Financing cost impact |

**Key regulatory bodies:**
- 发改委 (NDRC) — industrial policy, pricing
- 工信部 (MIIT) — manufacturing, tech, telecom
- 生态环境部 (MEE) — environmental compliance
- 卫健委 (NHC) — healthcare, pharmaceuticals
- 证监会 (CSRC) — capital markets
- 央行 (PBoC) — monetary policy

### Step 6: Key Drivers & Trends

**Secular trends (3-5 year):**
- Technology adoption (技术替代)
- Consumption upgrade/downgrade (消费升级/降级)
- Demographic shifts (人口结构)
- Supply chain localization (供应链国产化)
- Environmental transition (双碳/ESG)

**Cyclical factors:**
- Inventory cycles (库存周期)
- Capacity utilization (产能利用率)
- Pricing trends (价格趋势)
- Demand momentum (需求 momentum)

### Step 7: Investment Themes

**Thematic angles:**

1. **Policy-driven**: 国产替代, 新基建, 乡村振兴
2. **Demand-driven**: 消费升级, 老龄化, 出海
3. **Supply-driven**: 产能出清, 行业整合, 龙头集中
4. **Technology-driven**: AI应用, 新能源, 生物医药创新

**For each theme:**
- Investment thesis
- Key names to express the theme
- Timeline and catalysts
- Risks and headwinds

### Step 8: Trading Ideas

**Ideas shortlist (from sector overview):**

| Idea | Ticker | Direction | Thesis | Catalyst | Risk |
|------|--------|-----------|--------|----------|------|
| | | Long / Short | | | |

### Step 9: Report Structure

**Standard A-share sector overview format:**
