At the present stage of economic policy in Ukraine, the problem of attracting new investments, especially foreign ones, is particularly important for increasing country’s potential. Promotion of enterprise’s economic activity is possible due to the effective attraction of external and internal investment resources for the implementation of investments projects. It is important to provide a comprehensive approach to assessing the investment attractiveness of investment projects in the context of the main stages of their life cycle, especially their pre-investment phase, in order to make the optimal management decisions. This stage involves the following steps: analysis and evaluation of investment intentions and their compliance with investment opportunities; choice of project’s ideas and goals, definition of its tasks, which ensure the implementation of strategic plans; development of a detailed business plan and feasibility study of the project; conducting analysis and independent examination of the project; identifying alternative investment opportunities to achieve strategic goals; prospective analysis of future income and expenses during the project operation phase; investment risk analysis; examination of institutional compliance of the project implementation opportunities in the given political and legal platform. At this stage, it is necessary to ensure a secure solution for the following analytical problems: substantiation of alternative investment choices; assessing the potential effectiveness of the project; the payback period; compliance with environmental legislation, etc. If it is found out during the complex analytical evaluation of the project that the proposed project cannot be fully financed from internal and external financing sources at this stage, then it is no longer advisable to carry out further analysis of their performance indicators and to accept the proposed investment project for implementation.
