摘要: 当前，我国正处于海绵城市建设的关键时期，但公众参与度不足、参与体制不健全等问题都不利于海绵城市建设的试点推广和长效运营。通过调查公众降低洪涝风险支付意愿来量化评估公众对海绵城市建设试点的支持程度和参与意愿。以江苏省3个省级试点城市（南京、苏州、连云港）为例，构建基于洪涝风险和海绵城市认知的支付决策框架，通过结构方程模型检验影响因子及其作用机制。结果显示，虽然公众对海绵城市关注度较低但支付意愿较高；海绵城市认知和洪涝风险认知是支付意愿的主要影响因子，不同城市的公众支付意愿及其影响因素有所差异。
Abstract: Nowadays, China is in a critical period of sponge city construction, but the lack of public participation and unsound participation mechanism impede sponge city construction in the long run. This study aims at analyzing the extent of public support and participate desire for sponge city via estimating public willingness to pay (WTP) for reducing flood risk. Public WTP is estimated in three pilot cities (Nanjing, Suzhou, Lianyungang) in Jiangsu province, and a decision-making framework based on flood risk perception and sponge city perception is constructed, and the impact factors and its interaction mechanism are examined through structural equation modeling. This study indicates that most people are willing to pay though they are unfamiliar with the sponge city initiative. Sponge city perception and flood risk perception are the major determinants of WTP, but WTP and influencing factors varies in different cities.
