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.
The government acquires land into its reserve, prepares it and resupplies it.

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
绍兴市“绍芯谷”城市更新
Shaoxing relocated dozens of dyeing and chemical plants across county boundaries to dedicated industrial zones, then redeveloped the vacated 6,988-mu Mahai area as "Shaoxin Valley" for semiconductor-related industries. A menu of "four categories, ten methods" let each landowner choose self-redevelopment, joint development, buy-out or exit instead of blanket government acquisition.
Average floor area ratio after self-redevelopment below 1.0 → above 2.0
福州市福兴经济开发区提质增效
A 30-year-old development zone in central Fuzhou, 80% built out, revitalized 1,100 mu of inefficient land without new construction-land quotas. Tools included a parcel-by-parcel data base, property-for-property swaps for expropriated warehouse owners, tiered 20–50-year industrial land leases and a much faster approval process.
Industrial output per mu 3.67 → 4.73 CNY million
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.
佳木斯市纺织厂家属楼保护利用
Four 1952 Soviet-style workers' housing blocks, listed as historic buildings but rated structurally unsafe, were bought out from 217 households and converted into 189 affordable rental homes. The case presents this as China's first conversion of a listed historic building into affordable rental housing, with rents funding upkeep.
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
上海市江场西路申林木业城市更新
Two state-owned groups — the land's owner Bailian and the Shibei industrial-park company — formed a joint venture to redevelop an old timber-yard site. The land was taken into the reserve, rezoned for R&D at a floor area ratio of 3.5 and won back by the joint venture as Jing'an District's first "standard land" sale, with a contractual tax target of CNY 165 million a year.
Floor area ratio 0.32 → 3.5
淮南市毕家岗矿区业态重塑
A coal mine closed in 2003 and ecologically restored in 2016 still sat idle because of overlapping tenure and an outdated mining land use. The district government recovered the land from the mining group, rezoned it, bundled factory land with utilities in a single supply package, and offers standard factories on a "lease first, transfer later" basis.
Floor area ratio 0.3 → above 1.5
赣州市南康区老旧家具产业集聚区集约提质
Three self-built furniture workshop clusters of tin sheds on 5–10-mu plots were re-plotted from 66 scattered holdings into 60 regular parcels. A transparent "land-share ratio" formula gave each firm net land in proportion to what it originally occupied, after deducting roads and fire lanes, so that firms could rebuild multi-storey factories themselves.
Average floor area ratio 0.5 → 2.0
长春市水文化生态园一体化改造
Changchun's first waterworks (1932), closed in 2015, had become an informal public park but its land was still zoned industrial. The city took it into the reserve, allocated 25.95 ha back to the owner as parkland, and sold 3.33 ha of commercial and parking land as a bundle together with tourism and parking operating rights — a "combined supply" of land and concessions.
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.
常州市金坛区乡村产业“串珠成链”
A long, narrow crab-farming town with scattered small plots outside the urban development boundary revived about 500 mu of old village-enterprise land through 16 projects. Five industrial nodes along roads and rivers link processing, cold chain and logistics to the crab ponds; some collective land was contributed as equity, giving villages a share of rents.
Investment intensity 1.5 → 3.0 CNY million per mu
