The Role of Technological Structures in the Formation of Agglomerations

Abstract


 The article on the example of the city of Yekaterinburg and a number of other industrial cities of the Middle Urals shows the role and influence of the technological structures of different generations on the formation of the planning structure of large and largest industrial cities. The development of Ekaterinburg's planning has been shown, since the 18th century, the process of the formation of agglomeration around it since the 30s of the XX century has been considered.
 
 The article also considered the agglomeration effect, which develops in the planning of industrial cities when they create enterprises of III and IV technoLogicaL structures. Under his action, the planning system of the "city-agglomeration" is formed, as a specific form of development of the largest city. The authors for the first time proposed this new concept in urban planning theory, which makes it possible to characterize the development of a spatially distributed city with a set of reLativeLy isoLated parts, which in this particuLar case is manifested through the so-called system of socialist cities. The role of these socialist cities in the formation of a "city- agglomeration" is considered, the phenomenon of local self­identification of their inhabitants is shown, which consider their isolated region as a territorial entity existing separately from the central planning area, which is identified by the inhabitants of the "metropolitan city" with the notion of "city".
 The phenomenon of the withdrawal of industrial sites mainly from the central planning zones of the largest industrial cities is considered. The conditions for the development of the agglomeration effect for thelargest cities are determined, this effect was classified in the Scheme of the appearance of agglomeration effect in city planning. The final conclusion is made that the phenomenon of formation of a "city-agglomeration" should be taken into account in the development of master plans of industrial cities as a potential opportunity for the development of their planning structures, which affects the development of transport and social infrastructures.
