Mainland disclosures: prepare comparable source documents

Use official disclosure entries to locate source documents, then process permitted local copies in your own environment. This is a source guide, not a bulk-data adapter. Checked 2026-10-30.

Choose the source and document

SSE disclosures and SZSE company announcements are starting points. For other boards, use their own official entries. Confirm issuer and listing venue rather than searching by a short name alone.

Field	Preparation example	Failure to avoid
Identity	Full name, code, venue	Similar-name company
Report	Full report, amendment if any	Summary as complete evidence
Period	January–September, not “Q3” alone	Cumulative/quarter confusion
Scope	Consolidated and same unit	Parent-only mixed with group
Version	Original or restated comparative	Silent replacement

Download only through permitted access. Record title, URL, publication date, reporting start/end, unit and file digest. An announcement landing page may change; preserve the identity of the selected document.

Worked check

In our synthetic example, nine-month revenue is 1,120 and half-year revenue is 700, both RMB millions on the same basis. The derived third quarter is 420. If the comparative year’s analogous figures are 1,000 and 650, its quarter is 350: quarter growth 20%, cumulative growth 12%. Keep both labels. Balance-sheet receivables are dated balances and cannot be treated as cumulative flows.

If a correction changes the half-year scope, do not subtract until reconciled. If only a screenshot is readable, obtain a transcription with original locations and verify every amount; OCR success is not accounting comparability.

Rights, costs and credential boundary

Public reading does not automatically authorize automated harvesting, caching or commercial redistribution. Read the source’s current notices and obtain specific permission when needed. This guide supplies no bulk redistribution entitlement and does not repackage exchange PDFs. If using an account-based vendor, check its agreement independently; configure credentials in that vendor or your host, never on this website.

The initial workflow uses user-provided or publicly readable documents, with no new paid-data purchase. Your model or optional parser may still cost money. Source coverage and historical availability vary; no all-A-share completeness or strict point-in-time dataset is promised.

Recovery and verification

Blocked downloads remain failed; do not bypass controls or substitute another company’s report. Missing comparatives produce needs-input. Check each calculated row against two source locations, then retain a period bridge for the next report. No source in this directory is labeled already connected solely because its webpage opens.

Continue with the quarterly case and period-bridge preparation.
