Blue carbon has been recently recognized worldwide as one of the various carbon reduction measures. There are three types of blue carbon in the South Korean Ocean: salt marsh, seagrass meadow, and tidal flat. This article strives to assess the economic value of blue carbon judged by the public by the use of a choice experiment (CE). Chosen attributes for the CE application were the area of salt marsh, the area of seagrass meadow, and the number of tidal flats. A CE survey of 1000 households was successfully implemented throughout the country. All the estimates for the three attributes and price held statistical significance. The yearly household economic values arising from one unit (1 km²) increase in each attribute were computed to be KRW 202 (USD 0.18), KRW 238 (USD 0.21), and KRW 331 (USD 0.30), respectively. This quantitative information can be used in calculating the economic benefits of a blue carbon restoration project and performing cost-benefits analysis on the project. The results demonstrate that for all three types of blue carbon, the economic benefit of restoring 1 km² of each blue carbon type was at least five times greater than the cost of restoring it. In other words, the restoration of blue carbon is socially profitable.

蓝碳最近已在世界范围内被公认为各种减碳措施之一。韩国海洋中存在三种蓝碳：盐沼、海草草甸和潮滩。本文力求通过选择实验 (CE) 来评估公众判断的蓝碳的经济价值。CE 应用程序选择的属性是盐沼面积、海草草甸面积和潮滩数量。在全国范围内成功开展了对 1000 户家庭的 CE 调查。对这三个属性和价格的所有估计都具有统计意义。一个单位（1 km ²) 每个属性的增加分别计算为 202 韩元（0.18 美元）、238 韩元（0.21 美元）和 331 韩元（0.30 美元）。该定量信息可用于计算蓝碳恢复项目的经济效益并对项目进行成本效益分析。结果表明，对于所有三种类型的蓝碳，恢复每种蓝碳类型 1 km ²的经济效益至少是恢复成本的五倍。换句话说，蓝碳的恢复是有社会效益的。
