Research of Project Investment Control Based on Life Cycle Theory

Project Investment Control runs through the whole process of project construction, and after the future decision-making stage, the design, tendering, construction, and the final account of the cost-control effect determine the final results of project investment control. In this paper, reference to relevant examples of actual projects, not only discusses the factors that affect the project investment during each stage of project implementation, but also suggests some corresponding control measures in use of life cycle theory, designed to provide reference for investment control of project construction.
