单因素分析法是经济决策中常用的敏感性分析方法，存在与实际情况不完全相符的局限性，为此提出了财务净现值的多因素敏感性分析方法。首先分析财务净现值对各因素敏感性系数及多因素变动的临界条件，然后通过具体实例对财务净现值多因素变动的不确定性进行理论计算和探讨，从而为投资主体进行投资决策提供参考，并给出风险防范措施。

Single factor analysis method has been commonly used for sensitivity analysis in economic decision, which is not completely correspondent with the actual situation, so multi-factor sensitivity analysis is proposed for financial net present value (FNPV). In this paper, sensitivity coefficients and boundary conditions of FNPV to various factors are analyzed firstly, and then the uncertainty of FNPV under multivariate changes is calculated and discussed with specific examples, which could provide references to investment decision and present measures for risk prevention.
