摘要
以2011年全国31个省市建筑企业的数据为基础,运用三阶段DEA模型,对剔除外部环境因素和随机干扰因素影响前后的建筑企业效率进行测算、分析及实证研究。指出地区发展水平与产品的需求能力对建筑企业效率存在显著影响;在剥离环境因素与随机误差影响后,我国建筑企业技术效率整体不高,地区差异较大,主要原因是规模效率较低、投入产出配置不合理造成的。
Based on 31 provinces and cities in 2011 of our country construction enterprises' related data,using the three-stage DEA model,the article calculates,analyzes and empirically studies the construction enterprise efficiency in our country before and after the elimination of the external environment factors and the random disturbance factors.The analysis results show that:on the one hand,regional development and regional demand for the product capacity have significant influence on the efficiency of construction enterprises;on the other hand,after stripping environment factor and the random error influence,our country construction enterprise technical efficiency as a whole is not high and the regional differences,mainly because of the scale inefficiency and unreasonable input-output configuration.
