摘　　要：互斥项目备选方案间具有排他性,只能在备选方案之间选择其一。原始投资额相等且项目计算期相等的互斥项目比较决策,可选择净现值或内部收益率大的方案为最优方案;原始投资额不相等而项目计算期相等的互斥项目比较决策,可采用差额净现值法或差额内部收益率法来评判方案的优劣;项目计算期不相等的互斥项目比较决策,可选择方案重复法或最短计算期法来评判方案的优劣;原始投资额与项目计算期都不相等的互斥项目比较决策,可采用等值年金法。Between mutually exclusive alternatives, one of them can only be chosen. If the original investment amount and the period of the project are equal, the largest net present value or internal rate of return should be chosen for the optimal solution; if the period of the project is equal but the original investment amount is not, we can use differential net present value approach or differential internal rate of return approach to evaluate the scheme;if the period of the project is not equal, we can use scheme repeat approach or the shortest life expectancy approach to evaluate the scheme; if the original investment amount and the period of the project are not equal, we may use the equivalent annual annuity approach.
