中文摘要:
      [目的]研究铁路弃渣场施工"资源效率-环境效率-经济效率"的"三位一体动态施工综合效益率",为"四节一环保"应用于铁道弃渣场施工带来的水土保持及长远效益提供依据。[方法]基于绿色施工理念和最大化水土保持带来的多维效益,以传统Malmquist模型为基础,以弃渣场施工为研究主体,引入施工所致的非期望产出,充分考虑资源的投入利用率以及动态投入的长远效应,构建铁路弃渣场施工Malmquist模型(QMPI)。[结果]QMPI模型充分解释了铁路弃渣场"资源效率-环境效率-经济效率"三位一体的动态施工综合效益。基于DEA-SOLVER PRO软件平台进行了QMPI施工全要素生产率及其分解效率的测算,得出了各要素的冗余率。[结论]施工综合效益率与资效效率(REC)和环效效率(EEC)呈整体正相关,即绿色施工会促进施工综合效益率。同时,提升"四节"会促进"一环保",从而共同作用提高施工效益。
英文摘要:
      [Objective] To study the trinity dynamic construction comprehensive efficiency rate of "resource efficiency-environment efficiency-economic efficiency" in the construction of railway dregs field, in order to provide the basis for the study of soil and water conservation and long-term benefit brought by the application of "four sections and one environmental protection" in the construction of railway dregs field. [Methods] The green construction concept and the multidimensional benefits of soil and water conservation was considered. The traditional Malmquist model was employed as a foundation. The construction of dregs field was taken as the research subject, the Malmquist model (QMPI) for construction of railway dregs field was established by introducing the unexpected production caused by construction, with the fully consideration of the utilization of resources and the long-term effects of dynamic investment. [Results] QMPI fully explained the dynamic construction comprehensive benefits of the "resource efficiency-environmental efficiency-economic efficiency" of the railway dregs field. The construction total factor productivity and decomposition efficiency of QMPI were calculated based on the DEA-SOLVER PRO software platform. Meanwhile, the redundancy rate of each element was analyzed. [Conclusion] The construction comprehensive efficiency rate is positively correlated with resource efficiency change (REC)and environment efficiency change(EEC), that is, green construction will promote the comprehensive benefit rate of construction. At the same time, the promotion of the "four savings" will promote "one environmental protection" and thus work together for higher construction benefits.
