With the new normal of social and economic development, all industries are facing the upgrading and innovation of business models, and are also under tremendous pressure from the “survival of the fittest” system of the external market. However, the investment management level of engineering projects plays a decisive role in the core competitiveness of the industry. Engineering projects are projects based on engineering construction and are one-time engineering construction tasks that are managed. Investment management is a basic link in engineering projects and determines the efficiency of the project. In recent years, many unfavorable factors in engineering projects have affected the improvement of the efficiency of the entire construction industry, such as the imperfect investment management system and the incomplete knowledge system of professionals, which will result in low project investment returns and constrain the development of the industry. Therefore, enterprises should optimize the allocation of existing resources as soon as possible and continuously improve investment returns. First, the basic effective content of engineering projects and the investment management theory of engineering projects are explained. Secondly, the existing problems in the investment management of the Energy Project are analyzed ways are proposed to address these problems. The purpose is to improve the investment management level and improve the investment efficiency of engineering projects.
