In order to explore the key factors and management strategies of project cost control, this article adopts literature analysis method to deeply analyze various factors that affect project costs, including decision-making in project planning phase, management in construction phase, and changes in external environment. Research has shown that scope determination and design scheme selection in project planning have a significant impact on cost control, and technology and human resource management in the construction process cannot be ignored. In addition, market price fluctuations and changes in policies and regulations also have a significant impact on project costs. Based on these analyses, a series of effective management strategies have been proposed, including strengthening project planning management, implementing dynamic cost monitoring, and enhancing the ability to respond to external environmental changes.
