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.
