To restore and protect the ecosystem service function of coastal zones, some farmers have changed their certain original production methods and lifestyles and some have even relinquished a portion of the economic benefits that could be obtained directly. What impacts do the coastal zone ecological protection policies bring to the livelihoods of coastal farmers? The strict coastline protection of Beibu Gulf, Hepu County, Beihai City, Guangxi Zhuang Autonomous Region, China, is taken as an example. Combined with the sustainable livelihood framework (SLF), this paper set up an evaluation index system for the livelihood capital of farmers in the Beibu Gulf coastal zone, obtaining 568 valid questionnaires through a field survey, and use the propensity score matching and difference-in-difference (PSM-DID) method to study the impacts of a coastal ecological protection policy on the livelihood capital of coastal farmers from the perspective of farmer participation. The results show that (1) the coastal ecological protection policy had a significant impact on the natural capital and social capital of coastal farmers that actively participated in coastal ecological protection, which increased by 0.181 and 0.052, respectively. (2) However, it did not have a significant impact on the total livelihood capital, human capital, physical capital or financial capital. Therefore, this paper presents policy suggestions for constructing coastal ecological compensation mechanisms and for promoting active participation by coastal farmers in coastal ecological protection efforts.

沿海地区保护政策对农民生计资本有什么影响？农民参与视角的实证分析

为了恢复和保护沿海地区的生态系统服务功能，一些农民改变了其原有的某些生产方式和生活方式，甚至放弃了可直接获得的部分经济利益。沿海地区的生态保护政策对沿海农民的生计有什么影响？以广西壮族自治区北海市合浦县北部湾的严格海岸线保护为例。结合可持续生计框架（SLF），本文建立了北部湾沿岸地区农民生计资本的评价指标体系，通过实地调查获得了568张有效问卷，并运用倾向性得分匹配和差异化（PSM-DID）方法，从农民参与的角度研究了沿海生态保护政策对沿海农民生计资本的影响。结果表明：（1）沿海生态保护政策对积极参与沿海生态保护的沿海农民的自然资本和社会资本产生了显着影响，分别增加了0.181和0.052。（2）但是，它对民生总资本，人力资本，实物资本或金融资本没有重大影响。因此，本文为建立沿海生态补偿机制，促进沿海农民积极参与沿海生态保护工作提供了政策建议。
