Abstract Gomsoman Tidal Flat (GTF) in South Korea has been designated as a marine protected area in 2007, a Ramsar wetland in 2010, and a UNESCO Biosphere Reserve in 2013. However, as some area of it had been destroyed the Government plans to restore the destroyed area of the GTF. The objective of this article is, therefore, to investigate the public value of accomplishing the plan applying the contingent valuation (CV), a technique that asks randomly chosen people about their willingness to pay (WTP) for the accomplishment. For this purpose, a CV survey of 1000 households was conducted using a one-and-one-half-bounded dichotomous choice question format for a method of WTP elicitation and yearly household income tax for a payment vehicle. Since a number of interviewees (60.5%) reported zero WTP values, a spike model was adopted to analyze the gathered CV data with zero WTP observations. The mean household WTP was statistically significantly estimated to be KRW 3170 (USD 2.7) per year. The yearly national value is worth KRW 63.3 billion (USD 53.9 million). The benefits ensuing from the accomplishment are much greater than the costs involved in it.

韩国人愿意为恢复戈姆索曼滩涂付出代价

摘要 韩国的 Gomsoman 滩涂 (GTF) 已于 2007 年被指定为海洋保护区，2010 年被指定为拉姆萨尔湿地，并于 2013 年被指定为联合国教科文组织生物圈保护区。然而，由于部分地区已被摧毁，政府计划恢复GTF 被摧毁的区域。因此，本文的目的是调查应用或有估值 (CV) 来完成计划的公共价值，CV 是一种询问随机选择的人为完成该计划而支付的意愿 (WTP) 的技术。为此，对 1000 户家庭进行了 CV 调查，使用一个二分之一边界的二分选择问题格式，用于 WTP 获取方法和支付工具的年度家庭所得税。由于许多受访者 (60.5%) 报告了零支付意愿值，采用尖峰模型来分析收集的 CV 数据，其中 WTP 观察为零。平均家庭支付意愿的统计显着估计为每年 3170 韩元（2.7 美元）。每年的国民价值为 633 亿韩元（5390 万美元）。成就所带来的收益远大于其所涉及的成本。
