工程项目成本除直接成本和间接成本外,还有体制成本,机制成本和素质成本。后三项隐性成本加大了显性成本,并通过显性成本反映项目管理的效益水平。为此,简要介绍了体制成本、机制成本和素质成本,并就如何降低工程成本,提高经济效益提出了几条具体建议。 Project costs in addition to direct costs and indirect costs, there are institutional costs, the cost of machinery and quality costs. The latter three hidden costs increase the explicit cost, and reflect the benefit level of project management through explicit cost. Therefore, the system cost, mechanism cost and quality cost are briefly introduced, and some concrete suggestions are put forward on how to reduce the project cost and increase the economic benefit.
