摘要: 综合考虑经济和环境效率,采用DEA?Tobit 两阶段法对浦东新区的生活垃圾转运效率及其影响因素进行研究。第1 阶段,运用DEA 方法中的SBM?undesirable 模型分析上海市浦东新区13 个生活垃圾转运单元的综合效率,结果发现浦东新区生活垃圾转运的平均效率为0。668,普遍存在投入冗余和非期望产出过多等问题,且呈现北高南低的空间分布特征;第2 阶段,采用Tobit 模型对转运效率的外部影响因素进行研究,结果表明收集密度、垃圾分类和中转站的设备水平对生活垃圾转运效率有显著影响。

关键词: 垃圾转运效率, DEA?Tobit 两阶段法, 影响因素, 浦东新区

Abstract: By taking into account ecomic and environmental efficiencies comprehensively,the DEA-Tobit two-phase method was used to investigate transfer efficiency of municipal solid waste(MSW)and its affecting factors in the Pudong New District.In Phase One, the SBM-Model of the DEA method was used to analyze overall efficiency of the 13 MSW transferring units in the Pudong New District, and it was found that the mean MSW transfer efficiency was 0.668. Problems, like input redundancy, excessive undesirable outputs, etc. existed quite extensively in the district, and the spatial distribution of MSW transfer efficiency was characterized by being higher in the north and lower in the south. In Phase Two, the Tobit Model was applied to exploring external influencing factors. It was found that the collection density and sorting of MSW and equipment of the staging stations were the main factors affecting MSW transfer efficiency.

Key words: MSW transfer efficiency, DEA-Tobit two-phase method, influencing factor, Pudong District
