Abstract: | The aim of this article is to analyse the nexus of integration and disintegration processes in the post-Soviet space. On the one hand it considers ‘formal’ regionalism projects and the reasons for their inefficiency, and explores the real impetus behind the repeated attempts at top-down regional integration by post-Soviet elites. On the other hand, it analyses the bottom-up regionalisation of the post-Soviet space through the investment activity of Russian corporations, and demonstrates possible effects of this process for institutional development. |
