摘　　要：2019年起,我国在地级及以上城市全面启动生活垃圾分类,但目前尚缺乏其针对大中城市生活垃圾分类的经济效益分析。采用成本-收益法研究了湛江市生活垃圾分类的经济效益。对于收益单元,可回收物纳入政府监管体系后的经济效益最高(22119~34225万元/a),然后为假设进入末端处理设施的可回收物在前端回收带来的经济效益(4947万元/a)。厨余垃圾不同资源化路径的经济效益差异较大,具体为100%厌氧消化(2033万元/a)>50%堆肥和50%昆虫饲养(1742~1900万元/a)>100%堆肥(473~789万元/a)。此外,基于成本-收益法,参考《湛江市区生活垃圾分类专项规划(2020—2035年)》中的具体指标计算得出,湛江市生活垃圾分类工作可在第2次固定投资后的第5年(2040年)实现净收益。本研究填补了湛江市生活垃圾分类工作经济效益研究的空白,并可为其他大中城市核算生活垃圾分类的经济效益提供参考。Since 2019,China has fully launched municipal solid waste(MSW)classification in cities at the prefecture level and above,but there is still a lack of economic benefit analysis for MSW classification in large and medium-sized cities.Economic benefits of MSW classification in Zhanjiang city by using the cost-benefit methods were evaluated.For the revenue unit,the economic benefit of recyclables after being included in the government supervision system were the highest(221.19-342.25 million yuan/a).Followed by the economic benefit(49.47 million yuan/a)from front-end recovery of recyclables which were assumed entering the end-treatment facility.The economic benefit of different recycling paths of food waste were quite different,specifically,100%anaerobic digestion(20.33 million yuan/a)>50%composting+50%insect rearing(17.42-19.00 million yuan/a)>100%composting(4.73-7.89 million yuan/a).Furthermore,based on the costbenefit method and referring to the specific indicators in Zhanjiang Urban Solid Waste Classification Special Plan(2020—2035),it was indicated that Zhanjiang MSW classification work could achieve net income in the fifth year(2040)after the second fixed investment.This study filled the gap in economic benefit analysis for Zhanjiang city’s MSW classification and could provide a reference for other large and medium-sized cities to calculate the economic benefit of MSW classification.
