In this paper, the capital risk management of international construction by means of risk analysis is described. First, the traditional theories of capital risk analysis are discussed in detail. Then, possible capital risks in international construction contracting are analyzed and assessed systematically.Third,a series of mathematical models of assessing capital risks are established after analyzing the cash flow of the project. Based on the analysis mentioned above, computer simulation programs are developed.
