基于资本投资决策理论的工程方案决策与比选方法

研究目的：在基础工程项目建设的准备阶段，较为准确地预测工程方案的工程费用，选择出对不同主体（投资公司和社会）均较经济、合理的方案；真实地反应项目所消耗的“土地资源资产”的价值，为防止国有资产的流失提供合理依据。 研究方法：引入投资决策理论和机会成本分析理论，采用动态的工程费用计算方法，考虑工程方案整个比选期限内的全部费用。 研究结论：由于费用计算存在失真，所以同一个方案对于不同的主体而言，其经济性的评价结果是不一致的；引入投资决策理论，可以较为准确地预测工程方案的工程费用现值；利用机会成本分析理论，可以真实地反应项目所消耗的“土地资源资产”的价值；必须考虑工程方案整个比选期限内的全部费用，并采用动态的费用计算方法，才能较为全面、真实地反映工程的实际造价。

Decision-making and Alternative Method of Engineering Proposal Based on Capital Investment Decision-making Theory

Research purposes: In the construction preparation stage of basic engineering projects,the expenses of engineering projects are predicted accurately and the economical and reasonable proposal can be chosen for different principal parts(Investment Company and society).The value of "the land resources assets" consumed in the project can be reflected really and the reasonable basis is provided to prevent the state-owned assets from running off.Research methods:Based on the investment decision and opportunity cost analysis theories,the dynamic engineering cost calculation method is used for considering the total cost of project during the whole alternative period.Research conclusions:Because of the distortion of cost calculation,the economical estimate results of same proposal are inconsistent with different principal parts.Introduction of the investment decision-marking theory can forecast truly the present value of engineering cost in the engineering proposal.The opportunity cost analysis theory is used for reflecting really the value of "the land resources assets" consumed in the project.The total expenses of engineering proposal during the whole alternative period must be considered and the dynamic engineering cost calculation method is adopted to accurately reflect the real cost of engineering.
