Institutional Analysis Of Interregional Socio-Economic Convergence In The Context Of European Integration: Interdisciplinary Methodological Approach Development

Relevance. The problem of interregional convergence within EU-countries has been of great interest among scholars. Such an interest is explained by the fact that joining the European Union may cause deepening interregional disparities among EU-members. As a result, there is a need to develop a model of interregional convergence in socio-economic development that would help countries to face the challenges of regional development during the process of European integration. The multidimensional nature of issues relating to interregional disparities implies the usage of an institutional approach that allows an analysis combining economic and non-economic factors. The purpose of this paper is to develop an interdisciplinary methodological approach to the analysis of interregional socio-economic convergence in the context of European integration from the institutional perspective. Methodological basis. Valuable and very interesting studies along this research line have been undertaken by a number of scholars who have used different methodological approaches that include neoclassical analysis, "core-periphery" theory, institutionalism, "resource abundance curse" phenomenon. The outcomes of their studies serve as a solid ground for in-depth research on interregional convergence that allows analysing this phenomenon from different perspectives. However, the issues regarding the regional dimension of institutional influence on the socio-economic development in the context of European integration have not been thoroughly covered in the economic studies. Results. Based on analysis of theoretical and empirical studies in the areas of interregional disparities and institutional economics, the interdisciplinary methodological approach has been developed, which implies reaching the following objectives: 1) to analyse interregional disparities in EU-members within the framework of neo-classical growth theory, 2) to examine regional dynamics using methodology of "core-periphery" theory ("New Economic Geography"); 3) to research the presence of "resource abundance curse" phenomenon in the regional development in the EU-countries; 4) to examine the institutional dimension of interregional disparities; 5) to analyse position papers on the EU Cohesion Policy implementation to outline the institutional challenges of the latter. Therefore, the research output allows developing an interdisciplinary approach to the analysis of the institutional aspect of socio-economic convergence that combines a quantitative (empirical) and qualitative analysis.
