Analyze an industry or sector from a senior investment-banking perspective for ordinary investors by mapping the industry chain, identifying representative listed companies at each node, and writing a source-backed Markdown report. Use when the user provides an industry/sector/产业 name and asks for 产业链分析, 行业上市公司梳理, 投资银行视角分析, 商业模式/上下游/核心竞争力/护城河/竞争格局/风险揭露, or a visual Markdown investment reference saved under the current project's markdown directory.

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.
