【摘要】：传统三阶段DEA方法的模型选取仅限于径向或非径向测度方法,且通常从技术、规模和纯技术效率的视角出发,不考虑非期望产出。本文使用环境DEA技术将非期望产出考虑在内,并基于环境、经济和技术效率视角构建了改进的EBM-DEA三阶段模型,有效克服了仅用径向或非径向方法的不足。最后,使用该模型测算了我国2012年省际物流业的环境、经济与技术效率,结果表明:物流业环境效率整体偏低,经济效率呈现由东部沿海向西部内陆递减的趋势,加强环境管制可以提高经济效率,修正外部环境因素及随机误差后,东、中、西部的技术效率差异仍然很大。
[Abstract]:The selection of traditional three stage DEA method is limited to radial or non radial measurement methods, and usually does not consider undesirable outputs from the perspective of technology, scale and pure technical efficiency. In this paper, the environmental DEA technology is used to take the undesirable outputs into account. Based on the view of environment, economy and technology efficiency, an improved EBM-DEA three stage model is constructed, which effectively overcomes the shortcomings of radial or non radial methods. Finally, using the model of environment, economy and technical efficiency, China's logistics industry in 2012 provincial estimates the results show that the overall low efficiency of logistics industry environment, economic efficiency has decreased from the east coast to the inland west trend, strengthen environmental regulation can improve economic efficiency, external environmental factors and random error correction, difference technology the efficiency of the East and the west is still great.
