Project portfolio decision under the influence of financing risk
Most existing research on project portfolio decision-making only consider risk factors based on the project,but ignore the risks in the process of selecting upstream investors for financing.This paper proposes a quantitative formula to measure financing risk from both the local and overall perspectives,and constructs a project portfolio decision-making model considering the influence of financing risk.The results show that the decision results of project portfolio without considering financing arrangements have great financing risks.The financing channels for big projects that can contribute more income to the portfolio should be broadened and the impact of an individual investor's capital flow break on the overall project portfolio should be reduced.For small projects which can bring less income,investors who can provide stable funds should be selected in order to reduce the financing risk of the project portfolio,even though project income may be sacrificed to some extent.
