The study aims at valuing mangrove ecosystem services in Xuan Thuy National Park, Red River Delta, Vietnam. A discrete choice experiment was employed to elicit household willingness to pay (WTP) for a community project to protect mangroves against climate change. A conditional logit model and a random parameter logit model were estimated to identify the relationships between WTP and the different attributes of the mangrove conservation project. The results suggested that local households exhibited strong preferences for mangrove coverage area and storm-prevention capacity, whereas most respondents did not perceive biodiversity benefits. A high level of heterogeneity in household preferences was found for high mangrove coverage and high management level of biodiversity. Furthermore, marginal household WTPs were computed given a change in each attribute level. Hence, the findings will aid in the development of a comprehensive payment for mangrove preservation policy in Vietnam.

评估越南红河三角洲的红树林保护属性：一种选择实验方法

该研究旨在评估越南红河三角洲春水国家公园的红树林生态系统服务。采用离散选择实验来激发家庭为保护红树林免受气候变化影响的社区项目的支付意愿（WTP）。估计条件 logit 模型和随机参数 logit 模型来确定 WTP 与红树林保护项目的不同属性之间的关系。结果表明，当地家庭对红树林覆盖面积和防风暴能力表现出强烈的偏好，而大多数受访者并未意识到生物多样性的好处。由于红树林覆盖率高和生物多样性管理水平高，家庭偏好存在高度异质性。此外，考虑到每个属性级别的变化，计算了边际家庭 WTP。因此，研究结果将有助于制定越南红树林保护综合支付政策。
