| Along with the deepening of China’s reform and opening up, the market economic system has been constantly improved; economic growth achieved sustained rapid development. Especially the project investment of municipal government is very important for city development. Our country government investment project management system and management weaknesses still exist, resulting in many problems such as low efficiency, serious waste of resources, corruption and so. Therefore, to further deepen the reform of investment control of government invested municipal engineering project. People’s awareness of the investment control, is with the progress of the era development, productivity and management science theory and gradually establish and deepen, from the initial Home Furnishing construction investment control, investment control of large project development up to now for the subway, rail, overpass, such, experienced a long time summary, investment control of government investment projects mainly in decision-making phase of investment control, the investment control in the design phase, bidding and investment control, investment control of construction bidding stage and the completion acceptance stage investment control. Investment control is a system project, investment control in each stage of work between runs through the entire process of project implementation, only the owners, design, supervision and construction unit to participate in the joint efforts of all parties, in order to effectively control the project investment scale, can make more effective use of manpower, material resources, financial resources, so as to achieve maximum investment benefits, to achieve the ultimate goal of investment control.For a long time, due to factors such as system, mechanism of our country, often ignore the investment decision-making stage and design stage, is not fully pre work, insufficient scientific basis for project decision, serious phenomenon, causing great waste of investment. Along with the deepening of China’s reform and opening up, for the promotion of economic and social development, a large number of national investment projects have been put into the construction of large-scale construction is in urgent need of a set of advanced scientific theories and methods as the investment control basis, to avoid the phenomenon of super three, in order to improve China’s investment and the economic benefits of the construction project.
