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.

A coal mine closed in 2003 and ecologically restored in 2016 still sat idle because of overlapping tenure and an outdated mining land use.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.
