海绵城市是中国近年来城市建设与更新中被大力倡导的新概念，能够提高生态建设水平、缓解城市洪涝灾害问题和促进水的循环利用。海绵城市建设带来了人居环境的提升，提高了人们对住宅的支付意愿。该文以四川省遂宁市为例，定量分析了海绵城市建设对住房市场价格的影响。分析结果显示：建设海绵设施会使小区房价上涨年均385.2元/m2（即5.48%）；溢价出现的时点与遂宁市雨季出现时间一致；遂宁市通过建设海绵城市在房地产市场溢价方面带来的总经济效益为39.85亿元，考虑各方面贡献后整体效益为63.02亿元，超过了建设成本。
The sponge city method is a new concept that has been vigorously advocated in recent years in China's urban construction and renewal. This method improves the construction ecology, reduces urban flood risks and promotes water recycling. Thus, sponge city construction improves the living environment and enhances people's willingness to pay for housing. This study analyzes Suining city in Sichuan Province as an example to study the impact of sponge city construction on the housing market price. The analysis shows that sponge city construction increases the average community housing price per year by 385.2 Yuan/m2 (or 5.48%) with the pricing premium appearing from the rainy season in Suining. The sponge city construction increases the local economic benefit of Suining by 3.985 billion Yuan from housing price premium. The overall benefit is 6.302 billion Yuan considering all the contributions, which exceeds the construction cost.
