某个投资项目实施前,往往利用可研报告做投资可行性研究,通过项目投产后的经济评价结果判断是否符合投资要求,这就涉及NPV、IRR值的计算结果是否符合预期。在投资项目的经济评价中,这两个值是用EXCEL模板自带公式计算的,若抛开自带公式研究,这两个值是如何来的?有什么区别和联系? Before the implementation of an investment project, feasibility studies are often used to conduct feasibility studies on investment. The economic evaluation results after the project is put into production are used to determine whether the investment requirements are met. This involves NPV. Does the calculated IRR value meet the expectations? In the economic evaluation of investment projects, these two values ​​are calculated using EXCEL template own formula, if we put aside the formula study, these two values ​​come from? What is the difference and contact?
