AbstractIn the present study, phylogenetic relationships of European and Far Eastern representatives of the genus Aspidogaster Baer, 1827 were analysed: A. conchicola Baer, 1827, A. limacoides Diesing, 1834, A. ijimai Kawamura, 1915 and A. chongqingensis Wei, Huang & Dai, 2001. Based on ITS1–5.8S–ITS2 rDNA sequence data, an obvious differentiation was seen between specimens of A. limacoides sensu stricto from the European part of Russia and A. limacoides sensu Chen et al., 2010 from China (13.7%); the latter parasites were recognized as A. chongqingensis. Aspidogaster chongqingensis was more closely related to A. ijimai than to A. limacoides s. str. Specimens of A. ijimai from the Amur River, Khanka Lake (Russian Far East) and China were grouped into a single clade with low intra specific molecular differentiation (d = 0–0.3%). Specimens of A. conchicola from the European part of Russia, the Russian Far East and China also formed a single distinct clade. Genetic differentiation between European and Chinese samples of this species was two times lower (d = 0.45%) than between Russian Far East and European or Chinese samples (d = 0.96%), suggesting a long-term separate existence of A. conchicola in the Russian Far East.

For the Russians, Siberia has always been “Other” and, as a result, it has often been imagined as something other than what it is. As Mark Bassin argues in this richly detailed book, this habit of the Russian imaginaire was on full display during the mid-1800s when hopeful Russian observers and statesmen envisioned the Russian Empire's latest territorial acquisition—the Amur river in far eastern Siberia—as a new Mississippi and the region around it as a potential second America. Ultimately, of course, these geographical analogies proved well off the mark. The region of the Amur never went on to experience the prosperity of the United States and the Amur river never even remotely rivaled the importance of the Mississippi as an artery of trade and settlement. And what is so interesting about all this is that the Russians themselves began to have their doubts about the Amur within just a few years of annexing it. Bassin's work, in fact, concentrates on explaining this strange shift. It is a study of why the Russian vision of the Amur that began so hot ended up turning so cold so quickly and what the vision itself seems to reveal about the content of Russian national identity.

Subject. The article addresses the tax liabilities of taxpayers registered in the subjects of the Far Eastern Federal District, which should be paid to the consolidated budget of the Russian Federation, as well as the factors of the said debt growth. Objectives. Our aim is to assess the level of tax debt of regions of the Russian Far East and identify the correlation between the factors and the amount of tax debt. Methods. The study rests on methods of analysis, generalization, grouping, systematization, and the correlation and regression analysis. Results. We analyzed the level of tax debt for the entire Far Eastern Federal District and by region, identified factors affecting the growth of tax debt therein. The paper assesses the structure of tax debt by type of taxes and activity of debtors. The unveiled factors may help control changes in the size of tax debt in the Russian Far East and develop effective measures to improve the debt collection. Conclusions. The study shows that there is an increase in the tax debt in the regions of the Russian Far East, in the VAT in particular. The factor analysis revealed that the volume of sales of wholesale enterprises, investment in fixed capital, the consumer price index have the largest impact on the amount of tax debt.

The monograph presents the search for solutions to the problems of the Far Eastern region. The proximity of China and the remoteness from the center of Russia make us look for effective measures to overcome the problems of settling the Far East in the context of sustainable economic development of modern Russia. The paper analyzes the problems of the Far East: in industry, agriculture, forestry, energy problems, environmental problems, and provides recommendations for their solution. Considerable attention is paid to migration problems. The experience of China is studied through the prism of bilateral cooperation with Russia. It is intended for students, masters, postgraduates, researchers dealing with issues of macroeconomic regulation and forecasting.

The present paper analyses migration policy measures implemented in the Russian Far East, namely, State Programme to Assist the Voluntary Resettlement of Compatriots Living Abroad to the Russian Federation, the Far-Eastern Hectare Programme, establishment of Priority Development Areas (PDAs) and territories with a special regime of economic activity. The synthetic control method was applied to quantitatively assess how the adopted measures affect the migration outflow from regions of the Far Eastern Federal District. According to this method and relevant statistics, constituent entities of the Far Eastern Federal District were compared with control regions of the Siberian Federal District, where these policy tools have not been introduced. Comparable areas had similar socio-economic development trends and migration flows in the period preceding the implementation of the state programmes. To analyse the impact of migration policy changes in 2011–2018, the difference between outflow values of the Far Eastern and synthetic control regions was calculated. The results showed that the average estimated values are negative and significantly different from zero. This indicates a positive effect of new migration mitigation measures on reducing the outflow from the Russian Far East. Future research will separately assess the effectiveness of each migration policy tool implemented in the Far Eastern Federal District.

The earliest pottery from the Russian Far East, Osipovka and Gromatukha cultural complexes, was radiocarbon-dated to c. 13 300–12 300 BP. In Siberia, the earliest pottery is known from the Ust-Karenga complex, dated to c. 11 200–10 800 BP. The Osipovka and Gromatukha complexes belong to the Initial Neolithic, and they are contemporaneous with the earliest Neolithic cultures in southern China and Japan. In spite of the very early emergence of pottery in the Russian Far East, there is no evidence of agriculture at the beginning of the Neolithic, and subsistence remains based on hunting and fishing, including anadromous salmonids in the Amur River and its tributaries.

This study aims to measure the effectiveness of Russia’s Turn to the East Policy, addressed by the federal government in 2012, on the economic development of the underdeveloped Far Eastern regions, in terms of foreign direct investment (FDI) inflows data. To do so, this paper analyzed the results of the representative policy mechanisms - designed to promote the Far Eastern investments - of the Turn to the East Policy, comprised of the Eastern Economic Forum (EEC), Advanced Special Economic Zones (ASEZs), and Vladivostok Free Ports (VFPs), based on the secondary data from the governmental organizations. From the study, in spite of the previous contentions on those policy mechanisms amongst policymakers, we elucidate the incremental growing FDI - majorly contributed by the East Asian countries: China, Japan, and South Korea - propensity in the Far East. The three Eastern Asian countries promote investments in the Russian Far East for different eco-political purposes. And it further analyzed that for Russia, despite the remarkable magnitude of Chinese and Japanese FDI compared to South Korea, South Korea is still the most attractive partner, in terms of lack of threats: The Chinese expansionism, and the Kuril Island dispute with Japan.

In the current geopolitical conditions and fierce competition in world markets from such dy-namically developing countries of the Asia-Pacific region as China, Vietnam, Thailand, Singapore and a number of others, the preservation and increase of human capital in the regions of the Far Eastern Federal District is of a strategic nature. To ensure the national security and integrity of the country, to strengthen Russia's position in the Asia-Pacific area, the role of the Far East regions comes to the fore. However, the pronounced processes of depopulation of the population of the Far East regions and the stable migration outflow of the working-age population to other regions of Russia and abroad call into question the implementation of many tasks for the sustainable socio-economic development of this macro-region. The regions of the Far Eastern Federal District are already experiencing a shortage of qualified personnel in several industries. This deficit, in the absence of a governmental long-term strategy in the field of human capital formation, will not allow Russia to compete with the fast-growing economies of Asia-Pacific countries in the future. In this article, we analyze the opportunities and potential risks of human capital development through the prism of demographic processes occurring in the regions of the Russian Far East. Based on modern data on fertility, mortality, age-sex structure of the population, trends in interregional and international migration we conclude that for the growth of human capital and sustainable economic growth, the necessary conditions are: the development of transport and social infrastructure of the macro-region, the development of programs of labor mobility of the popu-lation, attracting young people through the educational migration channel, attracting international migrants from the CIS countries as well as from Asia-Pacific countries with a level of education and qualifications corresponding to the economic specialization of the regions of the Far Eastern Federal District.
