The Europe 2020 Strategy occupies a prominent place in the European Union's (EU) cohesion policy as a long-term programme for social and economic advancement. The main objective of the strategy is to implement the idea of smart, sustainable and inclusive development. An important priority implemented by EU countries in the context of implementing the assumptions of the Europe 2020 strategy is smart growth, i.e., the development of an economy based on knowledge and innovation. This requires significant spending on research and development and the use of mechanisms that enable the rapid transfer of theoretical knowledge into economic practice. The Europe 2020 strategy has set new targets for increasing competitiveness and accelerating the development of EU regions and countries. For all regions, including the economically weakest ones, the implementation of the Europe 2020 Strategy goals has been an important stimulus for the development and increase in competitiveness of EU regions. The decade just ending justifies carrying out assessments that must be intricately linked to the analysis of indicators set by the European Commission within the framework of the strategy's three priorities, i.e., smart, sustainable and inclusive development. The aim of the article is to assess the degree of implementation of the assumptions of the Europe 2020 Strategy in EU Member States. With the use of a synthetic indicator calculated using a multidimensional comparative analysis based on the Hellwig method, a ranking of EU countries, in terms of implementing the Europe 2020 Strategy assumptions, was established. The main indicators proposed by Eurostat for monitoring the Europe 2020 Strategy were applied for the assessment. As a result of the conducted research, conclusions were formulated regarding the importance of the Europe 2020 Strategy in the implementation of the cohesion policy principles in EU Member States. The research results show that the countries that have achieved the best results in the implementation of the assumptions of the Europe 2020 Strategy are also leaders in the ranking of competitiveness taking GDP per capita into account published by the European Commission.
