How Chinese cities are reusing
inefficient land

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.

9 cases

Paojiang, Shaoxing Binhai New Area, Shaoxing, Zhejiang · 6,988 mu · 465.9 ha

Urban Renewal of "Shaoxin Valley", Shaoxing

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.

Gongshu District, Hangzhou, Zhejiang · 547 mu · 36.5 ha

Transformation of the Hangzhou Iron & Steel Banshan Base, Hangzhou

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

Xialu District, Huangshi, Hubei · 10 mu · 0.67 ha

"Workers' Teahouse + Happiness Canteen" — Reusing an Idle Warehouse, Huangshi

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.

Jing'an District, Shanghai · 31 mu · 2.07 ha

Urban Renewal of the Shenlin Timber Site, Jiangchang West Road, Shanghai

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

Bagongshan District, Huainan, Anhui · 346 mu · 23.1 ha

Repurposing the Bijiagang Coal Mine Site as a Green Food Industrial Park, Huainan

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

Central urban area, Changchun, Jilin · 439 mu · 29.3 ha

Integrated Redevelopment of the Water Culture Ecological Park, Changchun

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.

Gusu District, Suzhou, Jiangsu · 61.5 mu · 4.1 ha

Self-redevelopment of the No. 1 Silk Factory — Conservation Through Use, Suzhou

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.

Binhai New Area, Tianjin · 1,545 mu · 103 ha

Transforming a Logistics Park into the Tianjin International Agricultural Products Trading Centre

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

Qinhuai District, Nanjing, Jiangsu · 19.5 mu · 1.3 ha

Urban Renewal of Jinling Changlefang, Nanjing

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.
