# Industry Chain Investment Analysis
## Objective
Produce a Chinese Markdown report for ordinary investors that explains an industry through its value chain, representative listed companies, business models, competitive positions, moats, risks, and investment-relevant tradeoffs. Act as a senior investment banker: evidence-driven, structurally skeptical, and clear about uncertainty.
## Required Reference
Read `references/report-framework.md` before writing the report. Use it for the report structure, company screening logic, analysis checklist, visuals, and risk language.
## Workflow
1. Clarify scope only when necessary.
- If the industry name is broad, pick a practical public-market scope and state the assumption.
- If geography is unspecified, cover globally and highlight China/Hong Kong/US-listed names when evidence supports them.
2. Gather current evidence.
- Browse current authoritative sources for industry structure, market size, regulation, listed-company filings, exchange pages, annual reports, investor presentations, and reputable market data.
- Prefer primary sources for company facts: annual reports, 10-K/20-F, prospectuses, official investor relations pages, exchange filings, and regulator filings.
- Use third-party research only to triangulate industry structure, market share, and competitive dynamics.
3. Map the industry chain.
- Split the industry into upstream, midstream, downstream, infrastructure/enablers, channels, and service/ecosystem nodes as applicable.
- For each node, describe value creation, pricing power, cyclicality, capital intensity, and key bottlenecks.
4. Select representative listed companies.
- Include companies only when they are materially exposed to the node.
- Give stock ticker, listing venue, main business exposure, and why the company is representative.
- Balance market leaders, specialized pure plays, and strategically important challengers. Do not force every node to have many companies if public-market coverage is thin.
5. Analyze companies.
- Cover business model, upstream/downstream relationships, revenue drivers, cost structure, core assets, competitive advantages, moat durability, competition, financial quality signals, and risk disclosures.
- Explain what ordinary investors can observe over time: metrics, filings, pricing indicators, capacity changes, order backlog, inventory, regulation, customer concentration, or commodity inputs.
6. Write the Markdown file.
- Save under the current project's `markdown/` directory. Create the directory if missing.
- Use a descriptive Chinese filename, for example `markdown/半导体产业链投行视角分析.md`.
- Include source links in Markdown. Avoid unsourced precise numbers.
- Add diagrams with Mermaid, SVG, or ASCII text when they improve understanding.
## Output Standards
- Write in Chinese unless the user asks otherwise.
- Separate facts, interpretation, and investment implications.
- Use plain language for ordinary investors, but keep the analytical standard professional.
- Include a non-advice disclaimer: the report is for research and education, not personalized investment advice.
- State data cut-off date using the current date.
- If evidence is insufficient, say what is missing and write a narrower report instead of inventing coverage.
## Visual Requirements
Include at least three useful visuals:
- A Mermaid industry-chain map.
- A comparison table of representative listed companies by node.
- One additional visual chosen for the topic: profit-pool map, value-chain bottleneck diagram, competitive landscape matrix, risk heatmap, or KPI dashboard.
Use inline SVG only when a compact custom visual is clearer than Mermaid or tables.
