Special tools for the development of regions of Russia as a resource of interregional integration

The diversity of regional situations in Russia requires a differentiated approach to building regional policies for different types of regions. Under this approach, a number of instruments have been developed to promote regional development, however they are based on the separation of regions and the strengthening of their vertical linkages. At the same time, the resource of synergistic development through interregional interaction remains virtually unused. In this regard, the purpose of the article was to inventorythe existing special regimes of regional development (special economic zones, clusters, regions of a special type, territories of advanced development and others), identify legislative opportunities for implementing interregional cooperation within their framework, and analyze actual results of such instruments in Russia. Based on the analysis of the legislative framework and the practice of using the special instruments under consideration, a range of measures has been formulated to accelerate their effectiveness in the methodological and institutional sphere. A range of mechanisms that will allow the inclusion of the criterion of interregional cooperation in the structure of relevant instruments is proposed. At the same time, the fact ofdifferentiation of possible additional (involving interregional ties) mechanisms depending on the type of region and the purpose of the implemented special development formats is taken into account.
