A-Share Theme Supply Chain Penetration

Problem

When researching A-share themes, the main gap is connecting end demand, leading companies, upstream suppliers, and listed targets across annual reports, prospectuses, and brokerage notes. This skill turns a theme into a traceable supply chain instead of relying on a single company or a conceptual narrative.

How It Works

• Five-level penetration: start from terminal demand, then identify core companies, top suppliers, listing status, and supply ratios layer by layer.
• Dual market-share view: record overall industry share and the share under a specific main line, such as the supplier’s share of a major customer’s procurement.
• Source priority: prefer prospectus, annual report, brokerage research, and industry association data, and cross-check customer-supplier relationships.
• Structured output: produce a layered penetration diagram, a Tier S/A/B beneficiary ranking table, and a one-sentence core thesis for each listed target.

Limits

Useful for industry-chain mapping and information organization, not for real-time trading signals. Depth depends on public data quality; prefer 2024-2025 data, flag older prospectus figures, and include a “not investment advice” disclaimer.
