基于社会总体偏差和同伴效应修正的海洋生态修复偏好研究

公众参与海洋生态修复对我国海洋环境保护与生态安全具有重要意义。利用单边界二分式引导技术评估青岛市居民海洋生态修复偏好,并从内疚和抵抗心理两方面就社会总体偏差与同伴效应对修复偏好的影响机理进行分析,为政府激发公众参与海洋生态修复的积极性提供理论依据与技术指导。结果表明:①青岛市居民平均每年愿意为海洋生态修复捐赠184.386元,考虑属性重要程度结果表明生物数量的改善可显著提高公众海洋生态修复支付意愿,而公众对改善海水水质和海岸环境并未表现出显著差异性偏好。②社会总体偏差和同伴效应均对公众海洋生态修复支付意愿表现出显著正向影响。③社会总体偏差和同伴效应可通过激发受访者的内疚感提高生态修复支付意愿,但也会导致抵抗心理抑制参与积极性;主观规范正向调节社会总体偏差和同伴效应对支付意愿的影响。研究揭示了公众在海洋生态修复中的偏好和竞争性心理对陈述偏好的影响,可为促进公众参与海洋生态修复和提高海洋环境资源价值评估准确性提供参考。

Marine ecological restoration preference based on the modification of social desirability bias and peer effects

The public participation in marine ecological restoration plays an indispensable role in marine environmental protection and ecological security in China. Employing the single boundary dichotomy guidance technology, this study evaluates the preference of Qingdao residents for marine ecological restoration, and attempts to reveal the factors that exert significant influences on residents'' preference for marine environmental protection. The research demonstrates that social desirability bias and peer effect are two main determinants of the residents'' preference for marine environmental protection, as the consequence of which, the study further contributes to unveiling the influence mechanism of social desirability bias and peer effect on the preference from the perspective of guilt and resistant psychology, which can provide theoretical basis and technical guidance for the Chinese government to stimulate the enthusiasm of the public to participate in the marine ecological restoration. The results show that the residents'' willing to pay (WTP) for marine ecological restoration is 184.386 yuan per year on average. According to the results that take the importance perception towards marine ecological restoration attributes into account, the improvement of the number of marine creatures can significantly improve the public''s WTP for marine ecological restoration, whereas the public shows no significant difference in preference for the improvement of marine water quality and coastal environment. In addition, this study also demonstrates that both social desirability bias and peer effect have significant positive effects on the WTP for marine ecological restoration. Finally, it is confirmed that social desirability bias and peer effect can improve the WTP for ecological restoration by arousing the respondents'' guilt, but the two variables can also lead to resistance psychology, thereby inhibiting the public''s enthusiasm to participate in marine ecological restoration. Subjective norms can positively moderate the effects of social desirability bias and peer effect on WTP for marine ecological restoration. The study identifies the influence of the public''s preference and competitive psychology on stated preference in marine ecological restoration, which can provide valuable reference for promoting the participation of social capital in marine ecological restoration and improving the effectiveness and accuracy of marine environmental resource evaluation. Therefore, on the basis of the aforementioned analysis, the findings of this study not only contribute to the understanding of the dynamics influencing public engagement in marine ecological restoration but also offer practical insights for policy-makers and stakeholders to foster a more proactive and inclusive approach towards sustaining marine biodiversity and ecosystems, ensuring the long-term health and resilience of marine environments.
