Hangzhou has drafted an AI industry promotion ordinance aimed at becoming China’s leading AI innovation city. The draft makes open source a standalone chapter — a national first — and seeks to build a full‑chain system covering open‑source community development, talent evaluation, foundation setup, licensing and compliance certification. It designs new institutional measures across compute, models, data, applications, talent, industry and industry‑academia‑research collaboration. The draft for the first time introduces the token concept and provisions to promote token production, allocation and use; proposes an open‑data liability exemption mechanism, incentives to commercialize open‑source technology and an open‑source security grading assessment; and proposes a flexible regulatory mechanism to modestly widen fair‑use boundaries for copyrighted training data while safeguarding lawful rights.
