Beach erosion, which is one of the significant marine environmental problems since it would negatively affect the beach environment, economy, and safety of areas near the beach. Then, this study examined the public perception and their willingness to pay (WTP) for the prevention of beach erosion. This study conducted a nationwide household survey for applying the contingent valuation method with one-and-one-half-bound dichotomous choice model. a nationwide household survey; in order to estimate mean WTP, the spike model was applied. As results, this study found that Korean households are positive to prevent beach erosion and the related policies should focus on ensuring the safety of the local areas. The mean WTP per household was KRW 2718.6 (USD 2.5) per year and total WTP of the Korean households was KRW 53.9 billion (USD 49.0 million) per year. Further, compared to the results of other marine protected areas, WTP of Korean households for the prevention of beach erosion is comparable with that of other marine protected areas.

海滩侵蚀，这是重大的海洋环境问题之一，因为它会对海滩附近地区的海滩环境、经济和安全产生负面影响。然后，这项研究调查了公众的看法和他们为防止海滩侵蚀而支付的意愿 (WTP)。本研究使用条件估值法和二分法选择模型进行了一项全国性的入户调查。全国家庭调查；为了估计平均 WTP，应用了尖峰模型。结果，本研究发现韩国家庭对防止海滩侵蚀持积极态度，相关政策应侧重于确保当地的安全。每个家庭的平均支付意愿为每年 2718.6 韩元（2.5 美元），韩国家庭的支付意愿总额为每年 539 亿韩元（4900 万美元）。
