SYSTEMATIZATION OF APPROACHES TO QUANTITATIVE ASSESSMENT OF INTERREGIONAL INTERACTION OF ECONOMIC ENTITIES
The interaction of economic entities is the basic condition for the functioning of the system of interregional relations, ensuring the uniform development of the country based on the free movement of economic resources. At the same time, despite the obvious successes in the field of research on the advantages and prospects of interregional cooperation, scientific achievements related to the quantitative assessment of the interaction of business entities operating in various regions remain quite fragmentary. The practical value of such an assessment is the objective substantiation of the mechanisms, incentives and tools to enhance interregional cooperation in the context of limited budgetary resources. The systematization of approaches to the quantitative assessment of interregional interaction of business entities conducted in the article revealed that the authors of most of the scientific works devoted to the problem of studying the intensity of interregional interaction are based on assessing the dynamics of interregional import and export of goods. Pointing to the narrowness of this approach, covering only one of the directions of regional development - economic, and only one target group - business, the article proves that the interaction cannot be complete if it does not cover such basic institutional structures as power, science and business cooperating with each other in order to achieve a high level of economic, social and innovative development of the territory. Given these shortcomings, the work argues the need for system modeling of the behavior of various actors, taking into account four basic approaches: structural modeling, game approach, neural network approach, statistical approach.
