基于硬件投入产出效益分析的上海市生活垃圾分类政策评价

本研究基于垃圾车、分类投放点、回收服务点、垃圾中转站4类硬件投入要素，以上海市垃圾分类政策实施效果作为研究对象，利用数据包络DEA分析方法，针对2020年1月~2021年6月上海市强制性垃圾分类具体的实施效果逐月展开分析和评测.结果表明，条例颁布后，上海市生活垃圾分类总体实施成效较为良好，综合效率、纯技术效率和规模效率平均值分别为0.957、0.993、0.963，均处于相对有效状态，但部分月份存在投入冗余及产出不足情况，仍有很大的进步空间.建议将投入要素均衡地作用到可回收物、干垃圾、湿垃圾以及有害垃圾的城市生活垃圾处理方面，进而提升上海市可回收物、干垃圾、湿垃圾以及有害垃圾的处理水平，提高政策实施效率.

Evaluation of municipal solid waste classification policy in Shanghai based on hardware input-output benefit analysis

Based on the four kinds of hardware input elements:waste truck, classified delivery point, recycling service point and waste transfer station, this study takes the implementation effect of Shanghai municipal solid waste classification policy as the research object, and analyzes and evaluates the specific implementation effect of Shanghai municipal solid waste compulsory classification from January 2020 to June 2021by using DEA method. It can be seen from the data analysis results that after the promulgation of the regulations, the overall implementation effect of domestic waste classification in Shanghai is relatively good. The average values of comprehensive efficiency, pure technical efficiency and scale efficiency are 0.957, 0.993 and 0.963 respectively, which are all in a relatively effective state. However, there are redundant inputs and insufficient outputs in some months, and there is still much room for improvement It is suggested that the input factors should be applied to the municipal solid waste treatment of recyclables, dry waste, wet waste and hazardous waste in a balanced manner, so as to improve the treatment level of recyclables, dry waste, wet waste and hazardous waste in Shanghai and improve the efficiency of policy implementation.
