Impact of Land Subsidence on Housing Sale Values
研究加州圣华金谷地面沉降对住房销售价值的影响，发现沉降导致房价下降2.4%至5.8%，对地下水管理政策有参考价值。
<h3>Abstract</h3> This study assesses the impact of land subsidence on housing sale values in the San Joaquin Valley, California. The study utilizes home sale transactions and vertical land-surface displacement data from Interferometric Synthetic Aperture Radar techniques. Using fine-scale fixed effects, matching, as well as a repeat-sales approach, our results indicate that land subsidence resulted in a 2.4% to 5.8% reduction in housing sale values, with the largest reductions occurring in areas where substantial subsidence occurred. Such findings may have implications for groundwater management and can potentially help inform policy design to help mitigate the causes and impacts of land subsidence.
