Case library · Unofficial English translation · Glossary
Twenty-nine case studies from the 2026 national collection on revitalizing existing and inefficiently used land — from aerospace parks on old textile sites to a soy sauce brewery that bought out its neighbours. Each case is translated in full, with its location, key figures and the land and planning tools it used.
Geographic spread
Province-level administrative boundaries come from the site's local China boundary dataset; points show the case cities.
Points mark the city of each case, not the exact site. The boundary geometry is loaded locally; no third-party basemap tiles are used.
Allowing several uses on one plot, e.g. industrial land with a share of commercial use.

无锡市扬名空天产业园产业升级
A 3,735-mu traditional industrial cluster in central Wuxi was consolidated by the district government and rebuilt by a state-owned platform as an "industrial community" for commercial aerospace. Multi-storey "skyscraper factories" raised the park-wide floor area ratio from under 0.8 to over 2.5, while tax revenue per mu tripled.
Park-wide floor area ratio below 0.8 → above 2.5
杭州市杭钢半山基地转型发展
After its steel lines closed in 2016, Hangzhou Iron & Steel Group redeveloped 547 mu of its retained land into a computing and data-centre cluster. Fragmented allocated and leased parcels were re-plotted and transferred back to the group by agreement under new planning conditions, ending what the case calls an "institutional freeze" on the land.
Floor area ratio, IT innovation centre 0.7 → 1.5
西安市未央区团结片区城市更新
A 13-square-kilometre area of northern Xi'an with fragmented tenure — approved-but-unsupplied land, land awaiting recovery and urban-village plots — was renewed under a city-funded, district-implemented joint land reserve. A railway park was opened up to surrounding streets, and TOD development was planned around metro stations.
唐山市青龙湖数据生态中心改造升级
Land next to an oilfield production area, hemmed in by well sites and pipelines and left undeveloped, was taken back into the government reserve and rezoned as new-type industrial land combining research and manufacturing. Multi-storey factories cut the building footprint by about 77% compared with conventional single-storey layouts; more than 40 firms have moved in.
Factory footprint vs. conventional layout 73,736 → 16,936 m²
郑州市亳都新象历史文化街区活化利用
A vacant former college campus inside the protected core of the Shang dynasty capital site was acquired, rezoned for mixed commercial and cultural use, and sold with heritage obligations — height limits, street pattern and a performance bond — written into the land contract. The courtyard-style district opened in 2025 and drew over 500,000 visitors in its first holiday week.
泸州市先市酱油厂升级焕新
A heritage-listed soy sauce brewery in a Sichuan market town expanded by buying out neighbouring vacant houses and a disused state grain depot, and by acquiring small leftover plots by agreement. Residential and public-service land was rezoned to industrial land with 30% commercial use allowed, linking brewing, a museum, homestays and an old-street tourism district.
Phase 1 output 1,000 → 2,000 tonnes per year
