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

摘要

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 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"or"regulating policy."
