Hangzhou Data Open Platform

Hangzhou's open-data portal (data.hangzhou.gov.cn) has published catalogues from 48 departments and 11 districts since being consolidated under China's first dedicated municipal data bureau, founded in 2017. Access is tiered: some datasets are free to view and download after registration, others need a formal application to unlock.

📊 Impact

As of September 2020 the portal's own user guide listed 613 open-data catalogues across 48 departments and 11 districts; a 2025 municipal work report set a target of roughly 100 additional catalogues for the year. Fudan University's independent 2024 China Open Data Index ranked Hangzhou first among China's sub-provincial cities for public data openness, its top tier.

🎓 Lesson

The catalogue is real and growing, but "open" here means free browsing plus a registration wall for downloads and a separate approval process for anything sensitive — a narrower kind of open than the no-strings catalogues this atlas tracks in Zurich or Montreal.
