Research findings

Comparative structure study

The largest recorded reporting jurisdiction, Jiangsu, contains 36 records (20.5% of this 176-record cohort). The remaining cohort contains 140 records. The comparison concerns archive composition.

The recorded reporting jurisdiction label Beijing accounts for 14.2% here (25/176), compared with 8.1% in the parent set (56/693), an absolute gap of 6.1 percentage points.

57/176 companies link to pages with existing source-supported excerpts (32.4% of the cohort). The other 119 records remain usable for archive composition, but do not support new operating case studies.
