基于DEA的建设工程项目技术创新效率动态评价方法

DEA Based Dynamic Evaluation Method of Technology Innovation Efficiency of Construction Projects

现有文献主要从区域、产业和企业等层面探讨技术创新效率评价方法。本文针对建设工程项目独特性和创新性特点,分别从工程过程管理和组织行为视角分析技术创新影响因素,确定效率评价的构成要素,运用系统动力学构建技术创新能力动态模型。同时,将动态模型与DEA算法结合,完整给出建设工程项目的技术创新效率评价方法。同时,以8个项目进行案例分析,得到各项目技术创新效率值及排序;并选取3个关键要素进行敏感性分析,结果表明提高专利工法申请量是提升效率的最有效途径。研究成果将为管理者提升项目管理绩效提供方法依据。

The existing findings focus on evaluation methods of technology innovation efficiency mostly in the fields of region,industry and enterprise.Considering the unique and innovative features of construction projects,the influencing factors from perspectives of engineering process management and organizational behaviors are given and analyzed. First,a factor framework for evaluation of project efficiency is presented,and then a dynamic model of technology innovation capability is provided by using System Dynamics. Secondly,based on the model combined with DEA,the dynamic evaluation method of technology innovation efficiency for construction project is proposed completely. Finally,a practical example is illustrated for eight construction projects to obtain technical innovation efficiency values and prioritize the projects. And sensitivity analysis of three key elements is carried out to show that the most effective way to improve efficiency is to increase the amount of patent application.The presented methods are useful for project managers to facilitate management performance improved.
