在社会主义市场经济环境下,企业存在的根本目的就是获取效益(或利润),而效益是由收入和成本之差决定的。工程项目的效益产生很大一部分都体现在工程项目的成本上,而工程项目的成本是指在这个项目施工的全过程中的全部生产费用的总计。提高工程项目管理效益水平的一个重大突破就是恰到好处的缩减节省这些直接成本和隐性成本。 Under the socialist market economy, the fundamental purpose of the existence of an enterprise is to obtain benefits (or profits), while benefits are determined by the difference between income and cost. A large part of the benefits of the project are reflected in the cost of the project, and the cost of the project is the total cost of production in the entire process of construction of the project. A major breakthrough in improving the efficiency of project management is the reduction of these direct costs and hidden costs.
