存量工业用地更新与政策演进的时空响应研究——以天津市中心城区为例

存量空间更新已经成为我国城市发展用地供给的主要途径之一。为应对存量空间中土地产权与交易成本的固有复杂性,相关城市政策需起到必要的导控作用。以天津市中心城区为例,探讨了存量工业用地的空间更新与政策演进之间的相互作用关系。首先,通过全途径调研构建空间更新数据库,对1995年以来存量工业用地的时空演变历程进行量化描述;其次,梳理1979年以来的相关城市政策,并对政策变迁的规律进行测度指标评价与分析;最后,通过比较研究,证实存量工业用地更新的进程受到政策演进的阶段性影响,而政策产生影响的反馈速度则受制于政策自身“引导型”或“规制型”的内在特性。

SPATIOTEMPORAL RESPONSES BETWEEN URBAN REGENERATION AND POLICY CHANGE OF STOCK INDUSTRIAL LAND: A CASE STUDY OF TIANJIN DOWNTOWN AREA

The regeneration of stock land has gradually occupied the mainstream of China’s urban development.In order to cope with the inherent complexity of land property rights and transaction costs in the stock land regeneration,relevant urban policies need to play a necessary guiding role.Taking the downtown area of Tianjin as an example,this paper discusses the interaction between spatial regeneration and policy change of stock industrial land.Firstly,a spatial database is constructed through multi-party research to quantitatively describe the spatial and temporal evolution of the stock industrial land since 1995.Secondly,the relevant urban policies since 1979 are sorted out,and the characteristics of policy changes are evaluated and analyzed.Finally,through comparative studies,it is confirmed that the regeneration rate of stock industrial land is affected by policy change,and the speed of policy impact is subject to the policies’ inherent characteristics,namely,"Guiding Policy" and "Regulating Policy".
