Development of methods for assessing the effectiveness of innovation and investment projects for sustainable development of the national economy

The article analyzes the methods of evaluating the effectiveness of innovation and investment projects for the sustainable development of the national economy. Today, the innovative potential of the state is one of the most important criteria for the country's competitiveness on the world stage.

It is necessary to present them to an external investor in order to prove the feasibility of investments in a separate project. The future of the business entity will depend on the correct calculation of the project's effectiveness. Evaluation of investment projects is carried out using a significant number of methods and indicators.
