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。%By taking into account economic 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⁃undesirable 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 spa⁃tial 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 explore external influencing factors. It was found that the collection density and sor⁃ting of MSW and equipment of the staging stations were the main factors affecting MSW transfer efficiency.
