What this page decides

Owner
01

This page owns AT06. Dominance is a market-definition and position analysis, not a brand slogan. Conduct (refusal to deal, discrimination, tying, unfair pricing, platform ranking or data access) is a second question. Platforms need side-specific analysis. Supporting screen: /china-antitrust-platform-dominance-screen. Private claims can run without a SAMR decision — Private enforcement L4.

Common failure points

Where files usually break

  1. Calling a successful app ‘dominant’ in a press release.

  2. Changing ranking to punish a discounter without an antitrust review (also RPM).

FAQ

Narrow follow-ups owned by this page

Do we need SAMR’s finding to be dominant?

SAMR is not the only path. Private cases can run on their own record. See Private enforcement.

Counsel hand-off

What to bring when you instruct

Instruct antitrust counsel. Bring: product description, any share work, the challenged rule, and SAMR contact if any.

Local context

Add the city only when it changes implementation.

Local SAMR practice can matter after the national question is identified.
