| Abstract: | A variety of approaches used in Soviet economic geography to define and measure the productive specialization of an economic region are reviewed. In the author's view, a regional activity qualifies as regional specialization if it helps shape the basic character of the regional economy. It is not sufficient for a regional activity merely to represent a major portion of a particular national sector of the economy. For example, the asbestos industry in the Urals represents the major portion of Soviet asbestos output, but asbestos does not shape the basic character of the Urals economy and is therefore not a principal specialization sector. Regional specialization derives from relationships among the various sectors of the regional economy, not from the significance of any particular commodity. A classification of economic sectors is proposed as an aid in analyzing the functioning of a regional economy: (1) the principal specialization sectors; (2) basic raw-material sectors; (3) associated sectors using the wastes and by-products of the principal sectors; (4) complementary specialization sectors, such as asbestos in the Urals; (5) auxiliary sectors, such as metallurgical fluxes for the iron and steel industry; (6) service sectors, including utilities, transportation, construction, trade; (7) local sectors, working for local consumption. |
