SIBERIA AS A MEGAREGION FROM THE ECONOMIC POINT OF VIEW
Vladimir KlistorinThe paper analyzes issues of how regional studies and allied disciplines react upon each other, and what are the main objectives and principles of economic zoning and classifying regions of various sizes accepted in economic science. From the economic point of view, regions are classified mostly proceeding from the purposes of management and analytics. The paper discusses the reasons of economic imperialism, i.e. invasion of economists into the adjacent fields of science. The major feature of an economic approach in historical - economic studies and regional ones is application of economic models, quantitative methods, and their own definitions. The paper presents a brief analysis of the studies concerning Siberia and its regions made by the Institute of Economics and Industrial Engineering of the Siberian Branch of the Russian Academy of Science in the Soviet and post-Soviet time. Siberia has been an object of cross-disciplinary research at least for two hundred years. The paper also compares the key ideas and approaches of the recent Siberia case-studies carried out by specialists of various sciences. The concept of megaregion from the point of view of economical science is discussed, and the corresponding directions of further research of Siberia are set.
