Diversification versus concentration trends in the housing construction and stock across Siberian regions

Relevance. The processes of regionalization and localization are currently intensifying in the Siberian macro-region, where local markets act as drivers of socio-economic development. We associate their development with the diversification of the sectoral structure. Nevertheless, the demographic conditions contribute to the growth of spatial concentration, which affects the sustainability of the housing construction structure and negatively affects the housing market.Research objective. This study aims to analyze the economic consequences of the diversification-related processes and the degree of the spatial concentration of these effects in Siberian regions. Data and methods. The study relies on official databases for the calculation of the Herfindahl-Hirschmann and Gini-Struck coefficients. Econometric analysis was conducted with the help of E-Views software.Results. The concentration phenomenon in housing construction becomes indirectly dependent on regional diversification of the urban and rural housing stock, with an intense and natural correlation for the urban housing stock, which is stronger than in the case of the rural housing stock. The multifactorial model of concentration in housing construction indirectly depends on the combined regional diversification of incomes and population and the urban or rural stock. Conclusions. The evolution of the Siberian macro-region is shaped by the increasing urbanization and localization processes, which exacerbate the insufficient level of diversification. These factors are detrimental to the development of the local markets of resources; they have a negative effect on the rate of housing construction and on the supply in the housing market.

Diversification versus concentration analysis in specific economic activities for assessing spatial differentiation within local markets

Diversification and concentration represent essential two opposite trends in many economic phenomena. Monopoly and monopsony are the natural limits in any market's analysis and describe together the range or the amplitude of offer and demand in economics. A lot of statistical indicators or coefficients, quantifying the diversification versus concentration phenomenon (D vs. C), can reveal a market, optimal or not, full or empty, etc. The paper sheds the light on the relatively little explored concept of economic evolution from concentration to diversification across local markets, providing novel evidence on underlining the dominance of diversification process within regions. This paper has applied statistical structure variable-based methods for assessing spatial differentiation degree within housing construction economic activity in macroregion Siberia for the sample period from 2000:Q1 to 2020:Q4. We present empirical elasticities using the multivariate OLS model that summarize the diversification economic response to the increasing processes of urbanization and localization across the Siberian regions. Some final remarks offer a distinct profile of this Russian macroregion under the influence of demographical variability

Impact local markets on development single-industry towns of mining regions: exploring the case of Khakassia

It is well-known that the life quality of monoprophilic territories is largely influenced by city-forming enterprises. The article considers the degree of influence of the city-forming enterprises of the coal industry on the development of agriculture of the industry of mono-profile territories in the region. In particular, the direction of the social vector in the activities of coal mining enterprises with regard to support of the corresponding the life quality in single towns has been revealed. Therefore, the material obtained as a result of the study can be used in the development of social development programs of monoprophilic territories with city-forming enterprises of the coal mining industry

Concept of intelligent system for controlling regenerative braking and using recovery energy

The issue of increasing the level of electrical energy recovered by the electric rolling stock and the efficiency of its use at the electrified sections of railways of JSC “Russian Railways” is still topical at present. This issue is considered today in the context of increasing the efficiency of the use of traction rolling stock. Increasing the energy efficiency of the transportation process by increasing the efficiency of recovery can be achieved both by the implementation of organizational decisions and through the introduction of additional equipment in the traction power supply system, for example, installation of reversible converters at traction substations or power storage devices on electric rolling stock and in the system of traction power supply, as well as other technical means, changing the parameters of the operation of sections with mandatory provision of the operability of the regenerative braking systems in the electric rolling stock. To assist in the reasoned adoption of similar and other managerial decisions, it is advisable to create an intelligent system for controlling the processes of applying regenerative braking and using recovery energy. This paper briefly reviews the main results of scientific research on the efficiency of recovery, suggests a mechanism for adapting the methods developed earlier to the system for controlling energy efficiency of recovery processes at the sections of railways

Determinants of regional agroindustry and spillovers between Siberian local markets

This paper investigates the relationship between spatial distribution of economic activity and local markets of primary sector in panel of Siberian regions over the period 2005-2018, using measure of localization that is Theil index considering two hierarchical levels. Section 2 describes the data and method using geospatial toolset that we have proposed, discusses the construction model for study spatial concentration spillovers between local markets. In Section 3 we study how the processes of urbanization and growth of population density in cities and agricultural development in rural areas affect the formation of local housing markets, and as a consequence, the associated local markets for goods and resources; and the last section concludes. Keywords: economic growth, regional economics, agricultural industry, local markets, spillovers, housing marke
