摘要:

城市土地利用格局是城市空间功能演变的结果和空间表现,对两者间关系的探讨是地理学经典研究领域。本文基于2003-2010年工业、商服、住宅用地微观出让数据,运用样带分析方法,研究南京市不同用途土地出让的时空演化及作用机制,着重探析“退二进三”和旧城改造、开发区建设、新城发展等城市空间重构行为对土地出让区位、规模与土地投标租金的影响。研究表明:总体上,南京市土地出让的空间用途结构和地价分布符合Alonso经典竞租模式,但也呈现多中心城市的特征;主城区地价水平较高,以小宗、密集的商服与住宅用地出让为主,旧城改造对提升老城区地价具有明显作用;郊区开发区为工业用地出让的主要区域,由于地价受行政影响较强,工业用地地价被压低,在同一工业园区空间范围内投标租金曲线呈现扁平化特征;新城通过改善生活生产服务设施,引致大量土地出让和土地价值提升,呈现一定的产城融合发展态势。

Abstract:

Urban land use structure is the result and spatial expression of the evolution of urban space functions. In geography, there is a classic field of study that dedicates to the relationship between these two aspects. Based on the industrial, commercial, and residential land leasing data during 2003-2010, this study examines the spatiotemporal evolution of different types of land use in Nanjing. By using the belt transect method, this study demonstrates especially the influence of urban spatial restructuring, such as the old city reconstruction, industrial upgrading, development zone construction, and new city development, on land grant location, scale, and bid-rent. The results show that the spatial structure of land market and land price tend to fit the Alonso bid-renting patterns, but there also exist multicenter characteristics. With higher land price, the remised land in the center of the city is usually small and of high density. Reconstruction of the old city increases land price significantly. Development zones have become a concentrated area for the transfer of industrial land, meanwhile industrial land price is artificially depressed because of strong administrative influences, which lowers the bid-rent curve slope within each industrial development zone. Moreover, new central business districts and university parks led to numerous land transactions and land value increased due to the improvement of peripheral conditions and supporting services. New cities with comprehensive functions may be formed in these places over a short time period.
