# Hebei Industry (河北内卷网)

> An international map of the industries of Hebei Province, China - "Made in China, made in Hebei": 107 industry clusters, 167 counties, 495 county-level industries, 310 products. Built to help buyers, researchers and AI agents understand what Hebei makes, where, and at what scale.

Hebei is the Chinese province that made "neijuan" (hyper-competition) famous. This site is industry-first (not a supplier directory): it tells you which county makes a product, how big the industry is and where it exports. Company pages (/enterprise/{id}) list only publicly verifiable representative companies with source links; the directory grows through public research and free listings (/join). The site is run as a public good for Hebei industry: no listing fees, no paid placement, no pay-to-rank.

## Entity model

product -> industry (county-level) -> region (county / city) -> supplier (reserved)
Each entity has a stable id: `sector:<slug>`, `industry:<county>:<slug>`, `product:<slug>`, `county:<slug>`, `cluster:<slug>`.
