In the conditions of deepening of transformational processes of development and formation of market relations in the system of world economy all branches of economy of Ukraine undergo significant transformations and reorientation. Under the influence of internal and external factors, the market environment changes. Despite the great resource potential, Ukraine fails to gain a leading position compared to economically developed countries. Therefore, it is advisable to study the current state of Ukraine's economy, analyze the dynamics of key indicators, assess the place in the world economy and find possible ways to improve the situation. As a result of the study, the main indicators characterizing the economic development of Ukraine for 2010-2020 were considered. Among them, the index of global competitiveness, the index of investment attractiveness occupy a special place. The analysis of the dynamics of these indicators revealed negative trends due to the aggravation of economic crises, hostilities in the east, the annexation of the Autonomous Republic of Crimea, destabilization of social and political life, the COVID-19 pandemic. It is determined that the main reason for this situation is the bankruptcy of domestic enterprises due to the low level of competitiveness and the inability to adapt to changing conditions of the external and internal environment and attract investment. The study proposed methodological approaches to assessing the level of investment attractiveness of the country and proved the importance of the ability not only to create new competitive advantages, but also to keep existing ones under the influence of a number of factors; Ukraine's ranking positions in comparison with other countries of the world according to the index of business conditions, the index of economic freedom, the index of global competitiveness, world competitiveness and world digital competitiveness are determined. It is established that the deterioration of rating places on these indicators requires the immediate development of new regulations, the choice of a new strategy for attracting investment, as well as the effective use of levers of influence on the economy.
