摘要：以深圳市为例，采用双重差分法和空间杜宾模型实证研究城市更新对周边住房价格的时空异质影响。研究发现：城市更新具有显著的空间正溢出效应，带动周边住房价格上涨。城市更新项目计划立项和开工建设后分别使周边住房价格提升了14.3%和13.4%，对房价的推升作用存在预期效应。城市更新对住房价格的影响具有空间异质性，对周边房价的推升作用随着中心距离增加而显著降低。城市更新对高中低价位住房的影响不同，随着住房价位提高推升作用逐渐减弱。

Abstract：Taking Shenzhen as a case，this paper studies the spatio-temporal heterogeneous effects of urban renewal on the surrounding housing prices by the difference-in-difference method and spatial econometric model.The results show that：urban renewal has a significant positive spatial spillover effect，which drives up the surrounding housing prices. The surrounding housing prices increase by 14.3% and 13.2% after the planning and construction time of urban renewal projects，urban renewal has an obvious expectation effect on housing prices. Urban renewal has spatial heterogeneity in the impact of housing prices，and the effect of pushing up surrounding housing prices decreases significantly as the center distance increases. Urban renewal has different impacts on housing at different price levels，and the effect of pushing up housing prices gradually weakens as housing prices increase.
Keywords：urban renewal；housing price；spatio-temporal heterogeneous effect；difference-in-differences；spatial econometric model
