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.

规划引领片区统筹，空间重构园区提质
Cities replan whole districts and parks at once — consolidating land, raising densities and mixing uses — instead of redeveloping plot by plot.
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
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
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.

弹性管控便捷许可，用途转换复合利用
Vacant schools, hotels, offices and warehouses are given new uses through rezoning, transition-period rules and faster permits.
沈阳市医大附属口腔医院盘活利用
Three vacant office buildings on allocated land in central Shenyang were rezoned for healthcare and sold on the secondary land market — Liaoning's first online public listing with timed bidding for allocated land — to a neighbouring dental hospital, which converted them into a second campus without demolition.
Floor space brought back into use 0 → 19,078 m²
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.
盐城市 8 号新生·数字科技创新园功能重塑
The vacant old campus of Yancheng No. 8 Middle School was rezoned from education to business office use and sold by public listing — with its buildings and a design scheme attached — to the district's urban investment company. A specialist operator turned classrooms into offices and labs and dormitories into talent apartments; 35 digital-technology firms now occupy 95% of the space.
Occupancy 0% → 95%
烟台市山东港口国际交流中心迭代更新
A disused 1980s seafront hotel owned by Yantai Port Group was demolished and rebuilt by the owner itself as an international conference and training centre. Without changing the land use or site area, the floor area ratio rose from 0.27 to 0.75 and about 9,400 m² of basement space was added.
Floor area ratio 0.27 → 0.75
黄石市“工友茶馆+幸福食堂”功能提升
An empty steelworks-company warehouse beside an old workers' housing estate was turned into a retro teahouse and subsidized community canteen for older residents. Using a five-year transition policy that keeps the original owner and land use unchanged, the subdistrict office avoided any transfer of title and paid for the hard renovation, while an operator fitted it out and runs it.

多元收储整合提效，规划优化空间盘活
Governments and state platforms acquire, consolidate and replan fragmented or constrained land — next to oilfields, on old mines, in self-built workshop clusters.
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

功能赋权资产增益，运营赋能历史记忆
Industrial and historic sites are reused for culture, retail and tourism, with land pricing and supply tools that make conservation pay.
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.
苏州市第一丝厂自主更新以用促保
China's oldest silk-reeling mill, on the moat at the southern gate of Suzhou's old city, was redeveloped by its own company as a culture, retail and hotel quarter for its 2026 centenary. Land use changed from industrial to commercial; the land premium of nearly CNY 70 million was assessed net of the high cost of building a basement car park around protected trees and heritage buildings.
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

明晰产权激活动能，分类处置降本增效
Complex or mismatched tenure — mixed allocated and sold land, unpermitted buildings, mismatched lease terms, surplus land — is sorted out so redevelopment can proceed.
天津市国际农产品交易中心转型升级
Half-empty warehouse land in Tianjin's port area was rezoned for a wholesale agricultural market. Because national logistics policy lets wholesale-market land be valued at industrial rates, no land premium was payable on the change of use — saving the operator nearly CNY 600 million — and the remaining lease term carried over to 2061.
Floor space 100,000 → 770,000 m²
南京市金陵长乐坊城市更新
A former knitwear factory turned Walmart, vacant since 2020 and next to the Confucius Temple area, had mixed allocated and sold land and 29,000 m² of unpermitted buildings. After penalties were imposed, the buildings were regularized, the owner paid CNY 233 million to convert allocated industrial land to commercial use, and the complex reopened as a culture-and-retail destination.
Floor space brought back into use 0 → about 40,000 m²
宁波市胜山创新园区联合改造
Three neighbouring bicycle-parts makers merged six small industrial parcels into one, rebuilt them together as multi-storey factories and shared roads, fire lanes and green space. Lease terms were aligned to a single expiry date, and after completion each building received its own title with shared land apportioned by floor area.
Floor area ratio 0.8 → 2.72
泉州市安踏（中国）有限公司并宗开发
Sportswear maker Anta merged five adjacent industrial parcels bought between 2005 and 2024. A Jinjiang rule let the merged site take the longest remaining term (to 2074) rather than the shortest, for a top-up premium of CNY 6.4 million, and planning indicators were balanced across the merged site, raising the floor area ratio from 1.4 to 4.0.
Floor area ratio 1.4 → 4.0
昆明市七彩云南庆沣祥分割转让
A tea company that no longer needed 72.5 mu of its 163.8-mu industrial site had the surplus split off as a separate parcel and sold it on the secondary market to a developer of standard factories. Because the law requires 25% of investment to be completed before land can be transferred, the buyer was allowed to register the transfer in advance and start building, with final title issued once the threshold was met.
Original parcel 163.8 → 91.3 mu
拉萨市龙腾大厦有机更新
Two run-down plots with incomplete land records — allocated government land and an old start-up centre of unclear title — were merged, rezoned commercial and transferred to a district-owned company together with the buildings on them. A minimum investment of CNY 250 million was written into the land contract; the new mixed office, retail and talent-housing complex opened in 2024.
Floor space under 15,000 → 52,307 m²

多措并举路径创新，资产重组司法衔接
Bankrupt or court-frozen sites and scattered rural plots are unlocked through debt purchase, auctions, restructuring and land contributed as equity.
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
临沂市科鲁特片区腾退整备
A bankrupt steel pipe plant's 199-mu site was frozen by repeated court seizures. A county state-owned company bought the bank debt, had the court auction the land, won it, then subdivided it for four new manufacturers — all in production within 18 months of launch.
Floor area ratio 0.3 → above 1.2
德州市卓越高新材料产业园拆改结合
A new-materials company bought all the assets of a bankrupt packaging firm by negotiation, then had a court confirm the sale and lift encumbrances so title could be transferred. Existing buildings were assessed one by one — some kept and refitted, most rebuilt — and the project started construction 45 days after obtaining the land.
Floor area ratio below 0.3 → 1.02
长沙市湖南广电“七彩盒子”整合盘活
One TV production campus sat on three plots — allocated land held by the broadcaster and sold land split between the broadcaster and its media group — so it could not be planned, permitted or mortgaged as one. The allocated land was injected into the group as a capital contribution instead of paying a CNY 123 million land premium, and the other plot's owner name was simply changed, unifying all 123 mu under one company.
湘潭市泰富重工整备焕新
A 1,510-mu heavy-machinery plant left empty by bankruptcy was taken over through court-supervised restructuring by Zoomlion, a firm whose products could use the existing sheds. Missing drawings and approvals were retro-fitted, and indicators were balanced across the area so a noisy test track could be moved away from homes — saving 300 mu of new land.
