Reviewing Transition Economies (1989-2021): Sustainable Reform Outcomes in Post-Socialist Countries

The article is devoted to the assessment of the results of reforms in transition economies for 1989-2021 using cluster analysis. The article allocates 27 indicators characterizing the main parameters of the transformations of 25 post-socialist countries of CEE, SEE, Baltic, South East Asia, former CIS countries, etc. Using the methods of elbow, silhouette and gap analysis, the optimal number of clusters for transition countries is determined. The Ward method was used to cluster the transition countries into two groups and to draw a diagram with the boundaries of the clusters. The first group includes countries that are less successful in reforming, and the second group includes countries that have achieved significant results in reforming. Based on the analysis, conclusions and recommendations are drawn towards social entrepreneurship development as a driving force of social innovative dissemination.
