基于DEA模型的建筑业环境行为效率评价研究

Research on Environmental Behavior Efficiency Evaluation of Construction Industry Based on DEA Model

对建筑企业进行环境行为效率评价是促进我国建筑行业健康可持续发展的重要手段。根据建筑行业特点及我国现有的企业环境信用标准,构建了建筑企业环境行为评价的投入产出指标体系,将改进的数据包络分析方法模型运用到企业环境行为效率评价领域,解决了现有企业评价研究主观性突出的问题,得出建筑企业评价分析方法。在此基础上对某代表性建筑企业2010-2017年环境行为数据进行了评价分析。分析结果表明该企业环境行为总体效率良好,但鉴于出现了奇数年和偶数年的效率波动情况,仍需提高环境行为效率。

Evaluating the efficiency of environmental behavior of construction enterprises is an important means to promote the healthy and sustainable development of China's construction industry.According to the characteristics of the construction industry and the existing environmental credit standards of enterprises in China,the input-output index system of environmental behavior evaluation of construction enterprises is constructed.The improved DEA model is innovatively applied to the field of environmental behavior efficiency evaluation of enterprises,which solves the outstanding subjectivity of existing enterprise evaluation research,and obtains the evaluation and analysis method of construction enterprises.On this basis,the environmental behavior datas of representative construction enterprises from 2010 to 2017 is evaluated and analyzed.The results show that the overall efficiency of environmental behavior is good,but in view of the fluctuation of efficiency in odd and even years,it is still necessary to improve the efficiency of environmental behavior.
