Миграция молодежи в региональные центры России в конце XX - начале XXI веков
On the basis of data for the 1989—2002 and 2003—2010 years, the migration of young people at the level of cities and areas of 19 Russian regions is analyzed. Migration is estimated by the “age-group shift” for the corresponding periods between censuses which provides more accurate estimates in comparison with the data of current statistics. Migration of young people has an expressed centripetal nature everywhere; their migration rate from the province is higher the farther one goes from regional centers. All regional capitals attracted young people in the period under review which has a positive effect on the age structure of their population, and only large cities could retain young people among their population. Migration of young people from the periphery is sustainable; it depends on the common migration attractiveness of regions and reaches the greatest extent in the East and in the depressed areas of the Center. In small and medium-sized cities on the periphery of regions, the outflow of young people almost always reaches the same intensity as in the countryside.
The article, based on current accounting data migration, analyzed the age characteristics of internal migration in Russia. The degree of influence of migration on the age structure of the population of 4 groups regions. On the example of the Central Federal District of the distributions increase (decrease) of population and intra-regional capitals periphery by age groups. More detailed analysis of migration age profile in Moscow and Moscow region.
Basing on the data of migrant population surplus/decline in Russian cities for the period 1991-2009 the attempt is made to evaluate the impact of the population size of a city as well as the city position in the system of central-peripheral relations on its migration balance. The author also explains the existing migration mobility pattern through hierarchy of cities within a region.
Subject Pursuing the socio-economic policy in regions requires understanding the processes of concentration of resources, population, enterprises in certain territories, mostly, in cities. Recent studies show increasing interest of economists in the Zipf's Law manifestation in the regional system, and cities distribution under the rank-size principle.
Objectives The aims are to test the Zipf's Law in Russian cities, to support or reject the hypothesis that in Russia the Zipf coefficient depends on the size of the geographical territory of the federal district.
Methods We used the least square method to analyze the Zipf's Law in Russian cities in general, and in each federal district, in particular. The sampling includes 1,123 Russian cities with population over 1,000 people in 2014. Results The Zipf's Law manifests in the entire territory of the Russian Federation. In federal districts, the Zipf coefficient ranges from -0.65 (the Far Eastern Federal District) to -0.9 (the Ural and North Caucasian Federal Districts). The analysis of the sampling of cities with population over 100 thousand people demonstrated -1.13 Zipf’s coefficient.
Conclusions The test of the Zipf's Law for Russian cities shows that it is valid for small (8,600-15,300 people) and large cities (66,700-331,000 people). The Zipf's Law fails for cities with population exceeding one million people (except for the city of St. Petersburg). The study supports the hypothesis on dependence of the Zipf coefficient on the size of a federal district.
On the example of advocacy support of National Population Census in 2010, some specifics features of public information projects under the existing regime of public procurement are considered.
We consider certain spaces of functions on the circle, which naturally appear in harmonic analysis, and superposition operators on these spaces. We study the following question: which functions have the property that each their superposition with a homeomorphism of the circle belongs to a given space? We also study the multidimensional case.
We consider the spaces of functions on the m-dimensional torus, whose Fourier transform is p -summable. We obtain estimates for the norms of the exponential functions deformed by a C1 -smooth phase. The results generalize to the multidimensional case the one-dimensional results obtained by the author earlier in “Quantitative estimates in the Beurling—Helson theorem”, Sbornik: Mathematics, 201:12 (2010), 1811 – 1836.
