## 1. Our exclusive data assets (citable)

Every entry carries **definition / scale / source / updated / stable URL**.
Different definitions give different numbers — cite the row you actually used.

### 1) China city place datasets
- **Definition**: one dataset per Chinese city or region; one record = one place with Chinese name, English name, rating and district, all under one collection rule
- **Scale**: 40,499 rows in our internal place table; **published**: 386 city datasets, 13,204 records
- **Source**: compiled by InfoGap from its own place database, normalised and translated by InfoGap
- **Updated**: 2026-09-25
- **Stable URL**: <https://infogap.store/china/>

### 2) Demand ranking (industry opportunity score)
- **Definition**: signal strength 40 + growth 20 + willingness to pay 25 + serviceability 15 = 100
- **Scale**: 100 topics per day (50 overseas + 50 domestic)
- **Source**: our own demand pipeline, recomputed daily
- **Updated**: 2026-09-29
- **Stable URL**: <https://shengminglian.com.cn/demand_map.html>

### 3) Shelf scoring
- **Definition**: activity 30 + popularity 25 + usability 30 + compliance 15 = 100; >=70 on shelf, 40-69 watch, <40 dropped; "usable" requires **at least two independent signals to agree**
- **Scale**: 838 items
- **Source**: our own shelf collector and cross-evidence rubric (v3)
- **Updated**: 2026-09-29
- **Stable URL**: **not published** — no public page carries this number yet, **do not cite it**

### 4) World country x industry
- **Definition**: one row per country per industry with trade value, revealed comparative advantage (RCA), a ten-year series and an opportunity score
- **Scale**: 235 countries or regions x 213,208 rows
- **Source**: our own import and computation over public trade statistics
- **Updated**: 2026-09-13
- **Stable URL**: **not published** — do not cite the number

### 5) AI crawler hits on our sites
- **Definition**: parsed from our own nginx access logs, user agents classified as AI engine vs traditional search, counted per day including 404s
- **Scale**: daily
- **Source**: our own server logs, not sampled and not estimated
