The feasibility study report is the foundational document for initiating large-scale infrastructure projects. The Development and Reform Commission uses the feasibility study report to approve, file, or give the green light to a project, deciding whether it should proceed. Companies also need to prepare feasibility study reports when applying for relevant certifications.

Feasibility studies are critical in determining the viability of construction projects before investment decisions are made. It involves a scientific justification through a technical and economic analysis of the proposed project. In investment management, a feasibility study entails research, analysis, comparison, and forecasting of the social and economic benefits after the completion of the project, including natural, social, economic, and technological aspects related to the proposed project.

On this basis, a comprehensive argument is made for the necessity of the project's construction, its financial profitability, economic rationality, technological advancement and adaptability, as well as the possibility and feasibility of the construction conditions, thereby providing a scientific basis for investment decisions.
