The dynamic development of integration processes in the global economy determines the relevance of assessing the effectiveness of international economic integration and examines the mechanisms of cumulative effect formation. Currently, there are no methodological approaches for a comprehensive assessment of countries economic integration effectiveness. However, there are theoretical issues representing the consequences of integration processes development. The research concerns with the effects of international economic integration and their quantitative assessment. The conducted analysis corresponds to the current stage of research. The purpose of the research is to provide a general assessment of international economic integration effectiveness based on the theoretical analysis of integration effects. This research considers the following aspects: systematisation of the types of effects generated by integration; analysis of quantitatively assessing direct integration effects; conditions for achieving a positive effect from a country's participation in integration; indicators of integration effectiveness; a general assessment of integration effectiveness based on indicators of economic dynamics for a number of integration associations; substantiation of promising areas of analytical research based on trends in the development of integration processes. The methodological basis is a systematisation of theoretically substantiated integration effects. However, the interrelationships between them determine the feasibility of using the method of summary indicators to assess the effectiveness of international economic integration. The research considers the practical aspects of analysing integration effectiveness. It aligns with national macroeconomic development goals and economic integration objectives: GDP per capita growth rates, comparative analysis of GDP and export dynamics, export quota dynamics. The basic research methods involve comparative analysis, retrospective analysis, summary indicators, and statistical methodology. The method of summary indicators has a theoretically substantiation and supported by an accessible information base. It is necessary to assess the effectiveness of international economic integration at several levels, assessment criteria, and methods. We performed a comparative analysis of the world's most significant integration associations. As a result, integration has a positive effect based on economic dynamics indicators. However, assessments of effectiveness as a factor in economic growth vary significantly across integration associations. Therefore, to assess the effectiveness of international economic integration there is a need in the additional research on the impact of integration processes on the global economy.
