This study applies Value-Belief-Norm (VBN) theory to investigate fishers' pro-environmental behavioral intention and their support for policies to reduce marine litter. While pro-environmental behavioral intention is often associated with personal environmental intention at the household level, policy support represents their support for government action at the political level. Therefore, we examine whether fishers are willing to engage in both of these dimensions. Data from 369 Vietnamese fishers are analyzed using structural equation modeling with FIMIX-PLS and PLS-POS. The results show that the sequence of values, beliefs, and personal norms can explain the fishers' pro-environmental behavioral intention and their support for policies addressing marine litter. Two segments of the fishers are detected from the sample with different perspectives of engagement intention. Fishers in segment 1 placed great emphasis on the consequences of marine litter on fishing activities as a motivator for their responsible actions. Meanwhile, fishers in segment 2 express pro-environmental engagement intention driven by the concern about responsibility and moral obligation. A binary logistic regression indicates that the risks of marine litter on fishing activity can provide the explanations for the differences between them. Our findings highlight both fishers' pro-environmental behavior and policy support as important strategies for dealing with marine litter in fisheries. If implemented simultaneously, they hold promise to alleviate the environmental and economic impact of marine litter in Vietnam.
本研究运用价值-信念-规范（VBN）理论来调查渔民的亲环境行为意图以及他们对减少海洋垃圾政策的支持。虽然亲环境行为意图通常与家庭层面的个人环境意图相关，但政策支持代表了他们在政治层面上对政府行动的支持。因此，我们研究渔民是否愿意在这两个方面都采取行动。利用带有有限混合偏最小二乘法（FIMIX-PLS）和偏最小二乘路径模型（PLS-POS）的结构方程模型，对来自369名越南渔民的数据进行了分析。结果表明，价值观、信念和个人规范的序列可以解释渔民的亲环境行为意图以及他们对解决海洋垃圾政策的支持。从样本中检测出两类具有不同参与意图视角的渔民。第一类渔民非常强调海洋垃圾对渔业活动的影响，以此作为他们采取负责行动的动机。与此同时，第二类渔民表达出的亲环境参与意图是由对责任和道德义务的关注所驱动的。二元逻辑回归表明，海洋垃圾对渔业活动的风险可以解释他们之间的差异。我们的研究结果强调，渔民的亲环境行为和政策支持都是应对渔业中海洋垃圾问题的重要策略。如果同时实施，它们有望减轻越南海洋垃圾对环境和经济的影响。
