结合某铁路建设工程实例,从项目前期、工程设计等不同阶段投资控制存在的问题入手,提出限额设计、加强细部分析等有效投资控制的措施和方法;并提出在实际工作中还应该加强主动控制与被动控制的科学结合,从而保证项目投资的有效控制。 Combined with an example of a railway construction project, this paper starts with the problems in investment control in different stages such as pre-project and project design, and puts forward measures and methods for effective investment control such as quota design and detailed analysis. It also proposes that in actual work, active control should be strengthened Combined with the passive control of science, so as to ensure the effective control of the project investment.
