Theoretical approaches to territorial-sectoral differentiation of Russian regions: sectoral aspect

Russian economy is characterized by significant heterogeneity of the economic environment. The ongoing structural and institutional transformations at the global and national levels reinforce the differentiation of the starting conditions for the territorial development in the social and economic level and the quality of life. Despite sufficient knowledge and maturity of theory and methodology of regional economics and its interdisciplinary nature, there are still some unsolved problems. These problems are connected with identifying the essence of territorial-sectoral differentiation which determines the need for the study in hand. It is based on the research conducted by the foreign and domestic authors who have contributed to the development of the theory of regional economy. The methods of the research mainly include the general scientific research methods, such as analysis, synthesis, abstraction, comparison, classification. To accomplish the tasks the authors use semantic analysis of literary sources. The analysis conducted and the classification of theoretical approaches to the description of territorial-sectoral differentiation made it possible to define the key features of the category. The authors tried to define the term of “territorial-sectoral differentiation†and thus, they expanded the area of the study and actualized the research within the framework of the problem under study. The definition of the territorial-sectoral differentiation allows making certain contribution into development of the theory of regional economics, expand the area of the research and point out the interdisciplinary nature of the area under study.
