| 海洋垃圾治理是实现海洋强国和海洋生态文明建设战略的必经之路。研究基于随机对照实 验构建差异化海洋垃圾治理政策情景，运用条件价值评估法和多边界离散选择引导技术调查我国 沿海 11 个省（自治区、直辖市）1 063 位公众支付意愿，结合规范激活理论实证探究公众对海洋垃圾治理政策的偏好及其异质性。结果表明：沿海省（自治区、直辖市）居民更加偏好海洋垃圾 治理短期政策。短期政策组、长期政策组和短长期混合政策组的支付意愿中位数分别为 235.15 元、
224.76 元和 206.91 元。道德规范会直接影响居民支付意愿，责任归属和结果意识会通过道德规范产生间接影响。并且道德规范较高的居民对于长期政策的偏好增强，对短期政策的偏好显著减弱。按照经济指标和环境指标分类，GDP 总量较高的地区和海洋垃圾较多的地区公众更偏好短期政策，GDP 总量较低的地区和海洋垃圾较少的地区公众对政策偏好差异不明显。研究揭示了公众对海洋垃圾治理的政策偏好及其影响因素，可为海洋垃圾治理政策制定和成本效益分析提供实证参考。 |

| Abstract: |
| Controlling marine litter is a critical necessity for the development of a maritime power and a strategic approach to marine ecological civilization．Employing a randomized controlled trial framework，this study constructs different scenarios for long-term and short-term treatment of marine litter．The contingent valuation method and multiple bounded discrete choice technology are used to investigate 1063 residents’willingness to pay in 11 coastal region of China. Furthermore，the norm activation model is used to empirically explore the resident’s preference and heterogeneity for marine litter treatment. The results indicate that: residents in coastal region express a stronger preference for short-term marine litter treatment．The median willingness to pay in the shortterm treatment group，long-term treatment group，and mixed treatment group are 235.15 CNY，224.76 CNY， and 206.91 CNY，respectively．Moral norms directly affect residents’willingness to pay，while awareness of consequence and ascription of responsibility have an indirect impact through moral norms. Residents with high moral norms have strong preference for long-term treatment，while their preference for short-term treatment is significantly weakened. According to the classification of economic and environmental indicators，residents in region with higher total GDP and more marine litter prefer short-term treatment，while differences in resident’s preference for treatment of marine litter control is not significant between region with lower total GDP and region with less marine litter．The study reveals the public’s policy preferences and influencing factors for marine litter control，which can provide empirical reference for the formulation and cost-benefit analysis of marine litter control policy. |
