屋上温室ビル(RGB)の普及は経済的需要と制度的準備の相互作用による土地利用転換として捉えられる。7都市の比較分析から、高強度の商業用RGBは富裕度の閾値を超えた場合にのみ出現し、法的永続性と行政的敏捷性が商業化のゲートを形成する。韓国は技術は優れているが規制が阻害する制度的パラドックスとして浮かび上がる。段階に応じた土地利用政策フレームワークを提案する。
English
This study reframes rooftop greenhouse building (RGB) diffusion as a land-use transition shaped by economic demand and institutional readiness. Comparing seven cities, it finds commercial RGBs emerge only above wealth thresholds, with legal permanence and administrative agility forming a commercialization gate. South Korea exemplifies a paradox of advanced technology but blocked regulation. A stage-differentiated policy framework is proposed.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の都市部では屋上緑化や農業が注目されるが、商業用RGBの普及は限定的。本論文の制度的準備の概念は、日本の規制や補助金制度を考える上で示唆に富む。ただし、GX政策との直接的な関連は薄い。
In the global GX context
Globally, urban agriculture is gaining attention for food security and sustainability, but commercial RGBs remain niche. This paper's typology and policy framework offer transferable insights for cities aiming to integrate agriculture into urban infrastructure, though its direct GX relevance is limited.
👥 読者別の含意
🔬研究者:都市農業と土地利用転換の理論的枠組みとして参考になる。
🏢実務担当者:屋上緑化や都市農業プロジェクトの事業化を検討する際の制度的条件の理解に有用。
🏛政策担当者:都市計画や農業政策において、経済的・制度的要因を考慮した政策設計の示唆を得られる。
📄 Abstract(原文)
Although rooftop greenhouse buildings (RGBs) have become multifunctional urban infrastructures that turn roofs into productive land, their commercial spread across cities remains highly uneven. This study examines that unevenness by reframing RGB diffusion as a land-use transition pathway shaped by the interplay of economic demand pull and institutional readiness. It develops this account as a proposition-generating typology rather than a statistical test. Methodologically, the study combines a qualitative thematic synthesis of the RGB literature with a comparative narrative analysis of seven cities across high- and middle-income tiers: New York, Paris, Singapore, Barcelona, Seoul, Bangkok, and Dhaka. The analysis describes an urban-agriculture intensification ladder on which high-intensity commercial RGBs emerge only above specific wealth thresholds. Linking this economic axis to two institutional channels—legal permanence and administrative agility—we construct a land-use typology in which a commercialization gate separates commercialized from research-stage RGBs. It also reveals South Korea as an institutional paradox, where world-class technology coexists with blocked regulatory channels. We conclude with a development-stage-differentiated, transferable land-use policy framework that helps planning authorities align institutional readiness with economic capacity while proactively mitigating green-equity risks.
