中文摘要：

在分析特大型工程项目多元主体多目标效用函数的基础上,构建特大型工程项目可持续均衡价值指数模型,分别提出经济、社会、环境生态分类价值指数和组合性均衡价值指数的计算原理和方法,并结合“三峡工程”进行了算例分析.研究表明：特大型工程项目可持续均衡价值指数的大小反映了项目内在价值的高低,它随主体信念和时空环境的改变而变化,据此可以判别项目的可行性和优劣性.

英文摘要：

Based on the analysis of multi-objective utility function of multiple main bodies of super-huge type projects, this paper builds sustainable balanced value index model of super-huge type projects, points out the calculating principle and method for classified value index of economy, society and environmental ecology and combinational balanced value index, and makes calcula- tion case analysis based on ＂Three Gorges Project＂. Research shows that the size of sustainable balanced value index of super- huge type projects reflects the internal value magnitude of the projects and changes with the change of main body intention and time-space environment, based on this, the feasibility, advantage and disadvantage of the projects can be determined.
