Abstract：Controlling marine litter isacritical necesityforthe developmentofamaritime powerandastrategic approach to marine ecological civilization.Employing a randomized controlled trial framework，this study constructs diferent scenarios for long-termand short-term treatment of marine liter.Thecontingent valuation method and multiple bounded discrete choice technology are used to investigate 1063 residents’wilingness to pay inllcoastalregionofChina.Furthermore，the normactivationmodel isused toempiricallyexplore theresident’s preference and heterogeneity for marine liter treatment.The results indicate that：residents in coastal region express a stronger preference for short-term marine liter 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 afect 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 economicand environmental indicators，residents in region with higher total GDP and more marine liter prefer short-term treatment，while diferences in resident's preference for treatment of marine liter control is not significant between region withlower total GDP and region with less marineliter.The studyreveals the public's policypreferences and influencing factorsfor marine liter control，which can provide empirical reference for the formulationand cost-benefit analysis of marine liter control policy.
