Abstract：Abstract ： Research purposes ： The engineering economic risl^ is systematically analyzed and studied from project， feasibility study，design，bidding and construction stage. This paper makes the risk analysis of engineering economy extend to the project proposal，feasibility study and project stage，studies the occurrence rules of engineering economic risks and risk control technology，and puts forward precautionary measures and suggestions，in order to provide reference for engineering project and engineering economic risk management. Research conclusions:( 1 ) In the project proposal， feasibility study and project stage， we should make decisions effectively and prudently，and strengthen engineering economic risk prevention and control of project decision - making stage，which can effectively eliminate 11 unfinished projec 11 unsustainable investment" and other major risk. (2) In the process of design，bidding and construction， risk control in every link is an important means of risk prevention of the implementation stage and attaining the project economic purpose. (3) We should formulate engineering economic risk management plan， perfect the mechanism of risk control system， and prevent risks from the whole process and all factors，to achieve the purpose and benefit of investment.
