TL;DR: In this article, the influence of digital technologies on the configuration of value chains and on the spacial location of production links of these chains is considered and an approach based on the analysis of real situations in individual industries is used to identify the changes under study.
Abstract: The transition to digital technologies is associated with an increase in consumer requirements in a saturated market. The influence of these technologies on the configuration of value chains and on the spacial location of production links of these chains is considered. An approach based on the analysis of real situations in individual industries is used to identify the changes under study. It is shown that the popular concept of the “smiling curve”, which characterizes the distribution of added value between the chain participants, needs to be adjusted when the supplier has unique competencies. The relatively high return on assets of such suppliers is demonstrated by examples. It is shown that firms that form global value chains strive to possess their own competencies that are most important for these chains. The risks faced by value chains in a downturn in the global economy and measures to improve the sustainability of such chains are considered.

TL;DR: The performance evaluation showed better bandwidth usage when deploying the proposed PS-PC method with ITTP protocol in comparison to the traditional ITTP Protocol without the PS- PC method.
Abstract: Voice over IP (VoIP) wastes a valuable amount of bandwidth because of its large packet header size compared to its small packet payload. The main objective of this paper is to reduce the amount of this wasted bandwidth, by proposing a new packets coalescence method, called Payload Shrinking and Packets Coalesce (PS-PC). The proposed PS-PC method reduces the amount of the wasted bandwidth by i) coalesces a group of VoIP packets in one header instead of a separate header to each packet and ii) shrinks the VoIP packet payload to a smaller one based on a certain algorithm. The proposed PS-PC method is deployed at the sender side VoIP gateway that represents an exit point to a myriad number of simultaneous VoIP calls. The performance evaluation showed better bandwidth usage when deploying the proposed PS-PC method with ITTP protocol in comparison to the traditional ITTP protocol without the PS-PC method.

TL;DR: It is argued that the user should be given an opportunity for selecting a combination of content-based and collaborative search that matches her interests and the context of a search query.
Abstract: The algorithms underpinning information retrieval shape its outcomes and have epistemological, social and political consequences. On the one hand, the Web search algorithms place a specific actor—the Web librarian (cataloguer), the document’s creator, the expert (“authority”), the user or the service provider (developer and operator of a search engine)—in the position of a decision-maker. Each of them has distinctive criteria of relevance in information retrieval. On the other hand, the application of those criteria determines what information the user receives. Content-based search places emphasis on the contents of retrievable documents whereas collaborative search shifts the focus of attention to opinions of experts and other users. The outcomes of content-based and collaborative searches diverge as a result. Depending on the information provided to the user, the development of her knowledge and socialization proceeds differently. A plea for customized Web search is made. It is argued that the user should be given an opportunity for selecting a combination of content-based and collaborative search that matches her interests and the context of a search query.

TL;DR: In this article, the design problem of a stochastic linear-quadratic controller over an infinite time-horizon with dynamic scaling of the coefficients in the state equation and the cost criterion is considered.
Abstract: This paper considers the design problem of a stochastic linear-quadratic controller over an infinite time-horizon with dynamic scaling of the coefficients in the state equation and the cost criterion. Dynamic scaling means multiplying the coefficients by a positive time-varying function. The optimality criteria used are extensions of the long-term average cost and pathwise long-term average cost. The integral of the scaling function is applied to normalize the performance indices. It is shown that, the optimal control law is time-invariant and can be obtained through a steady-state optimal strategy known for the autonomous system.

TL;DR: In this article, the authors examine the crisis of modern Western democracy and propose the concept of collaborative democracy, which is based on the analysis of the trends studied, and show that interparty competition inevitably generates a mechanism of degradation of moral norms in the political sphere and reduction of the political system efficiency.
Abstract: The article examines the crisis of modern Western democracy. It is noted that the important causes of the crisis are slowing down of economic growth and deepening inequality in developed countries. It is shown that inter-party competition inevitably generates a mechanism of degradation of moral norms in the political sphere and reduction of the political system efficiency. These processes have intensified dramatically as a result of the spread of the Internet. They contributed to the reduction of citizens’ participation in political life and at the same time to the ochlocratization of the political system. It is shown as well that a number of transformations taking place in the Western countries are aimed at improvement of interaction mechanisms between the state and society and contribute to overcoming the crisis. These include expanding the role of parliamentary committees, increasing the number of parties, largescale reforms of public sector governance basing on collaboration. In this context, the experience of e-platforms and the possibilities of institutional collaborative platforms are analyzed. The concept of collaborative democracy is proposed, based on the analysis of the trends studied. The mechanism for collaborative democracy should ensure greater choice and broader direct participation of citizens in decision-making, control the costs of political competition and maintain ethical standards, prevent ochlocratization and improve governance. Contours of this mechanism are outlined. It is based on the use of a proportional electoral system of a special type, a system of expert councils and collaborative platforms for public decision-making, as well as on the implementation of decision-making rules close to consensus. The significance of these conclusions for Russia is discussed.

TL;DR: This work parallelizes the extended path method for solving rational expectations models, and applies it to compute perfect foresight competitive equilibrium for the global economy with multiple goods, regions, industries, and households.
Abstract: We parallelize the extended path method for solving rational expectations models, and apply it to compute perfect foresight competitive equilibrium for the global economy with multiple goods, regions, industries, and households. At each iteration, first intertemporal variables are updated, then equations for intra-temporal variables are solved in parallel. We compare serial, and parallel, versions of the extended path method in high-performance computing environments based on scenarios with long time horizons that include future populations, economic growth, energy use, and carbon dioxide emissions. Relative to the serial version, the speedup factor for the parallel extended path method grows almost linearly up to about 30 times with 18 cores, and computing times reduced from over 10 h for the serial version down to about 20 min for the parallel version.

TL;DR: In this article, the authors show that the prices for electricity from renewable energy sources tend to decrease around the world and have already become lower than 1.5 rubles/(kW h) in the most advantageous projects.
Abstract: The prices for electricity from renewable energy sources (RES) tend to decrease around the world and have already become lower than 1.5 rubles/(kW h) in the most advantageous projects. However, this indicator in Russia has essentially higher values both at present and in the forecast for 2035, which is caused by the system effect of RES integration in the power system. In fact, renewable energy and conventional energy are antipodes in Russia and are in contradiction with respect to each other. The article substantiates the possibility of harmonizing them with each other from the viewpoint of the universal organizational science called tectology and gives examples of technological solutions for implementing this: changing the operation modes of electrical loads in the compositions of consumer electrical systems and development of distributed cogeneration in accordance with the schedule of electrical rather than heat loads as a result of separating the heat-recovery and consumption processes in time by using thermal energy-storage devices. In fact, this refers to achieving better structural stability of the energy sector based on an alternative concept of its development and transition to optimizing the operation of the inseparable process chain “production–consumption of fuel and energy resources,” which also includes new, renewable sources. Apart from decreasing the costs for integrating RES into the power system and making the prices for electricity from RES in Russia commensurable with those around the world, this will also result in a more efficient power supply as a consequence of more uniform loading of thermal and nuclear power plants, the use of the nonutilized potential of decreasing the specific fuel consumption for electricity production in the cogeneration mode, and decreased losses in distribution networks.

TL;DR: In this paper, the authors discuss the expediency of abandoning the tool of social forecasting in the practice of public administration in favor of planning and design methods, which is supported by such respected researchers as Douglas North, George Soros, Nassim Taleb and Arnold Toynbee.
Abstract: The article discusses the expediency of abandoning the tool of social forecasting in the practice of public administration in favor of planning and design methods. The methodological basis rests on the conceptual imperative of the impossibility to produce adequate forecasts in the modern world, which is supported by such respected researchers as Douglas North, George Soros, Nassim Taleb and Arnold Toynbee. The fairness of this thesis is illustrated using methods of comparison and analysis. The study analyses the main factors that cast doubt on the possibility and expediency of preserving the tool of social prognostics: the failure of the scenario forecast format; the need for foreknowledge of events rather than values of traditional macro-parameters; the extension of Arnold Toynbee’s principle from a historical retrospective to studying the prospects; the economic growth rate indicator (GDP) losing its indicative universality and the emergence of alternative measures of social development (Gross National Happiness, culture and environment preservation); critical attitude of the intellectual elite to the possibility of social forecasting; unreliability of the source statistics; the expectation of the end of economic growth, a change in the development regime and quantitative forecasting devaluation by the leading experts – Douglas North, Robert Lucas, Tom Piketty, Richard Heinberg; the completion of the mission of capitalism in the form of the Neo-Malthusian trap and robotomics (mass introduction of robots to the economy). The authors prove that amid fading interest in traditional forecasting, alternative prognostication methods are emerging, such as planning, designing, futurology, foresight and strategic intelligence. Devaluation of forecast tools leads to the need to change the old doctrine of public administration, based on forecast documents, to a new one implying a transition to active construction of the future through directive designing and planning. The theoretical and practical significance of the study lies in substantiating the principles of a new management system: expanding the planning and design horizon (up to 30 years); introducing a mechanism for implementing plans and projects; introducing mechanisms for pre-project foresight; creating a twolevel economic management system; and moving from the quantity paradigm to the quality one.

TL;DR: In this article, the authors describe the system logic of institutions, the reasons for institutional changes, especially caused by the current pandemic, highlights the problems and prospects for the development of the institutional economics from an ecosystem perspective.
Abstract: The development of institutionalism was not limited to the transition from the old theory to the new one: time is changing, the behavior of economic agents – ​carriers, voluntary or involuntary, of the institutions, whether formal or informal, is changing, – ​institutions that, in turn, are themselves the object of changes. This nature of the object under study poses a difficult task for researchers: to identify, with the help of changing (developing, adapting) tools, the essence of the modern institutions and the ones that can take place in the future, which is in a state of permanent development (evolution). The article describes the system logic of institutions, the reasons for institutional changes, especially caused by the current pandemic, highlights the problems and prospects for the development of the institutional economics from an ecosystem perspective. The latter circumstance presupposes going beyond the purely systemic approach to the study of the institutional system by including the features of the interaction of the system under study with the relevant metasystem, which forms a functional unity with the system and, therefore, is interpreted in aggregate as an ecosystem.

TL;DR: In this paper, the authors presented a study of patterns of changes in specific (per capita) electricity consumption (SEC) in developed and developing countries, as well as in Russian regions, demonstrates that Russia does not have preconditions for electricity consumption growth to over 1400 bn kWh under the high scenario of the demographic forecast and to over 1300 bn kg under the medium scenario.
Abstract: The presented study of patterns of changes in specific (per capita) electricity consumption (SEC) in developed and developing countries, as well as in Russian regions, demonstrates that Russia does not have preconditions for electricity consumption growth to over 1400 bn kWh under the high scenario of the demographic forecast and to over 1300 bn kWh under the medium scenario. While differences between SECs in developed and developing countries have been decreasing since the 1960s, SEC differentiation among Russian regions is increasing. The conclusion reached using tools of the technocenosis theory is that efforts should be focused not on electricity consumption growth in regions with high energy supply (those specializing in mineral production and metallurgy), but on increasing SEC in outsider regions. The problem of reducing differences in SEC between Russian regions is important for the structural stability of the national economy as a system.

TL;DR: In this paper, the authors proposed a model of interaction between small enterprises and banks based on trust relations, which makes it easier to obtain loans, and demonstrated the role of the B2B trust as a tool for establishing steady mutually beneficial contacts.
Abstract: The presented study touches upon two groups of problems that significantly affect the development of the Russian economy. The first of them is the creation of conditions for the expansion and formation of small business, which, in particular, is a priority area of one of the national projects. The second problem is the establishment of relations of interfirm trust in the domestic business environment, which is in demand in various sectors of the economy and has become, for example, the dominant topic of the St. Petersburg International Economic Forum. Hence, the paper aims to form, on the basis of trust relations, a model of interaction between small enterprises and banks, which makes it easier to obtain loans. The object of the paper is intercorporate (B2B) trust, and the subject is the improvement of relationships between small businesses and banks on the basis of trust. The methodological basis of the study is an integral approach that combines both institutional and sociological views on the phenomenon of trust, and the traditional economic analysis of the relationship between banks and their clients, small enterprises. The analysis showed, on the one hand, the complexity of the relationship between banks and small enterprises, and on the other hand, the prospects of these clients for banks. There was also demonstrated the role of the B2B trust as a tool for establishing steady mutually beneficial contacts of the subjects under consideration. The author concluded that the model of partnership between small enterprises and banks, based on the establishment of relations of trust between the parties, will stimulate investment processes in small business and support its development. The study presents the organizational solutions for the establishment of the proposed model.

TL;DR: It is concluded that the enrichment of the conceptual apparatus of the theory of spatial economics is a necessary prerequisite for the development of tools for implementing the sustainable development strategy in the digital and spatial dimensions.
Abstract: The article analyzes the backbone concepts of the spatial theory of sustainable development of modern countries – information space. The aim of the study is to substantiate the author's interpretation of the conceptual apparatus of spatial analysis, taking into account the principles of methodological institutionalism (comparative studies). In accordance with the purpose of the research, the following tasks are set and solved in the article: the essence of the information space in the system of sustainable development as a set of interactions of economic agents affecting the environment is disclosed; the attributive properties of the information space are formulated; the directions of its transformation under the influence of sustainable development processes are determined; the hypothesis about the transformation of the information space into information and communication under the influence of digitalization processes is formulated. It is concluded that the enrichment of the conceptual apparatus of the theory of spatial economics is a necessary prerequisite for the development of tools for implementing the sustainable development strategy in the digital and spatial dimensions.

TL;DR: In this article, the authors present the rating of Russian economics journals, taking into account their international success: entering the leading Web of Science and Scopus databases and presenting their content in English, using the author's algorithm for ranking journals make it possible to establish that at present 25 Russian periodicals in economics have reached a sufficiently high scientific level and have become competitive in the international market of scientific products.
Abstract: Data are presented for 2021 on the rating of Russian economics journals, taking into account their international success: entering the leading Web of Science and Scopus databases and presenting their content in English. The calculations carried out using the author’s algorithm for ranking journals make it possible to establish that at present 25 Russian periodicals in economics have reached a sufficiently high scientific level and have become competitive in the international market of scientific products. If the concept of the market is interpreted in the broadest possible sense—as a set of competing participants entering into specific transactions that give them certain benefits, based on supply and demand for their services—then we can talk about a kind of revolution in the market of Russian economics journals due to the widespread use of strict academic standards and raising the scientific culture of domestic researchers. At the same time, the authors point to some negative aspects in the development of the pool of leading journals, including their high geographical concentration in only seven cities of Russia. Comparison of the parameters of the market for economics journals and the markets for journals in related disciplines—history, sociology, political science, and philosophy—showed that the competition for the right to be published in a prestigious Russian journal among economists is much higher than among representatives of other social sciences and humanities.

TL;DR: In this article, an analytical method for predicting the efficiency of investments in the digitalization of the design, construction and operation of nuclear power plants (NPPs) at the microeconomic level, the costs of which ultimately affect the economic indicators of NPPs that determine the competitiveness of nuclear energy in the energy technology market.
Abstract: The article proposes an analytical method for predicting the efficiency of investments in the digitalization of the design, construction and operation of nuclear power plants (NPPs) at the microeconomic level, the costs of which ultimately affect the economic indicators of nuclear power plants that determine the competitiveness of nuclear energy in the energy technology market. As a criterion for assessing the effectiveness of investments in the digitalization of nuclear energy, it is proposed to consider the reduction in the cost and timing of the construction of nuclear power plants, which have the greatest impact on the competitiveness of nuclear power plants. The results of calculating the present value of NPP electricity, the investment payback period and the internal rate of return, depending on the observed delays and the corresponding growth in the cost of NPP construction, demonstrate reserves for their reduction due to the digitalization of business processes in the NPP life cycle.

TL;DR: The purpose of the study is to compare the indexes of innovative development of regions and identify indexes that do not have significant differences, and refine the results of correlation analysis and identify a subset of indexes that are not distinguishable when solving control problems parameterized using the differentiation characteristics.
Abstract: Currently, one of the priorities of the country's development is the transition of the economy to an innovative path of development. Analysis and evaluation of innovative development at the regional and national levels, quantitative assessment of regional innovation activity, and development of methods for evaluating the effectiveness of interaction between science and business that allow choosing the right strategies for solving management problems are of particular relevance. The subject of the research is the indexes of innovative development of regions. The purpose of the study is to compare the indexes of innovative development of regions and identify indexes that do not have significant differences. Eight indexes describing the innovative development of Russian regions are compared. We use four of the author's indexes, published earlier: the index of technical efficiency innovative space for international patent applications TEMPZ, the index of technical efficiency innovative space for patent applications TEPZ, the index of technical efficiency innovative space issued patents TEPV and the index of technical efficiency innovative space developed for new technologies TETECH. Along with the author's indexes, four other indexes with a similar applied focus are considered, published by the Institute for Statistical Studies and Economics of Knowledge (ISSEK) in National Research University — Higher School of Economics (HSE), RIA rating, and Association of Innovative Regions of Russia (AIRR). In the course of the study, a comparative analysis of the indexes of innovative development in the space of expert-defined characteristics of regional differentiation was made. Analysis of the cosines of the angles between the indexes constructed using the beta coefficients of the regressions of these indexes on the differentiation characteristics allows us to refine the results of correlation analysis and identify a subset of indexes that are not distinguishable when solving control problems parameterized using the differentiation characteristics.

TL;DR: In this paper, the authors studied the structure of the set of finitely generated groups of orientation-preserving diffeomorphisms of the line and the circle of C(1) smoothness with a given number of generators and the property noted above.
Abstract: Among the finitely generated groups of diffeomorphisms of the line and the circle, groups that act freely on the orbit of almost every point of the line (circle) are allocated. The paper is devoted to the study of the structure of the set of finitely generated groups of orientation-preserving diffeomorphisms of the line and the circle of C(1) smoothness with a given number of generators and the property noted above. It is shown that such a set contains a massive subset (contains a countable intersection of open everywhere dense subsets). Such a result for finitely generated groups of orientation-preserving diffeomorphisms of the circle, in the case of C(2) smoothness, was obtained by the author earlier.

TL;DR: In this article, a linear-quadratic control problem where a time parameter evolves according to a stochastic time scale is considered and an optimal infinite-time control law under criteria similar to the long-run averages is obtained.
Abstract: We consider a linear-quadratic control problem where a time parameter evolves according to a stochastic time scale. The stochastic time scale is defined via a stochastic process with continuously differentiable paths. We obtain an optimal infinite-time control law under criteria similar to the long-run averages. Some examples of stochastic time scales from various applications have been examined.

TL;DR: In this article, the authors proposed a general approach for building the scholarly consumption indicators, and presented the results of the experiments on evaluating a thematic structure of scholarly consumption for a given author, as well as for his suppliers and consumers.
Abstract: In recent years, large datasets of citation contexts from research publications have become available for scientometric studies. Such citation contexts contain different characteristics of relationships between citing and cited papers, including information about publications that were in some way used by citing authors, about the motivations of this use, etc. Some of these characteristics can be considered as indicators of scholarly consumption of the citing authors. Based on the citation contexts data, the scholarly consumption can be characterized by four indicators: (a) data on cited (consumed) publications and their authors (suppliers); (b) types of scholarly consumption; (c) its thematics; and (d) temporary changes in these data. The indicators can be grouped and merged in various ways based on belonging to common citation contexts and/or on the coincidence of their values. By this way, one can create datasets for various objects and tasks of scientometric evaluation of scholarly consumption. The article proposes a general approach for building the scholarly consumption indicators, and presents the results of the experiments on evaluating a thematic structure of scholarly consumption. For this, thematically significant groups of words (topics) were selected from the citation contexts by using the LDA topic modeling method. Topics are obtained from the citation contexts for three groups of publications: (1) publications of a given author, (2) publications cited by a given author (suppliers), and (3) publications citing a given author (consumers). Thematic structures of scholarly consumption for a given author, as well as for his suppliers and consumers have been built. The features of the thematic structure representation in the forms of a tree of words and a flowchart are considered.

TL;DR: In this article, a probabilistic interpretation of the elements of the matrix, which is used to assess the economic complexity in accordance with the traditional approach, is presented, on the basis of which aggregate indicators are introduced that characterize the nesting of the structures of strong sectors of regional economies.
Abstract: The paper presents a probabilistic interpretation of the elements of the matrix, which is used to assess the economic complexity in accordance with the traditional approach. Their properties are given, on the basis of which aggregate indicators are introduced that characterize the nesting of the structures of strong sectors of regional economies. It is shown that aggregate nesting indicators are statistically significant explanatory variables for economic complexity. It is proved that the used procedure for calculating the economic complexity is correct in the sense of the existence and uniqueness of the solution. It is shown that the data that are used to assess the economic complexity in accordance with the author’s approach allow to reflect the formation of value chains and groups of related sectors focused on both the external and internal markets. For this economic complexity, calculated on regional data, its high values correspond to large values of the aggregated nesting indicators. Low values of economic complexity correspond to low values of nesting indicators.

TL;DR: In this article, the starting positions of Russian agar export in the implementation of the federal project have been determined, consisting in weak diversification, a low level of intra-industry trade, and a decrease in competitiveness for products of high value added.
Abstract: Russian Abstract: Определены стартовые позиции российского агарного экспорта при реализации федерального проекта, состоящие в слабой диверсификации, низком уровне внутриотраслевой торговли, снижении конкурентоспособности по продуктам высоких переделов. Оценен потенциал роста экспорта по товарам, не обладающим сравнительными преимуществами, и по конкурентной сельскохозяйственной продукции – зерну и подсолнечнику. Russian Abstract: The starting positions of Russian agar export in the implementation of the federal project have been determined, consisting in weak diversification, a low level of intra-industry trade, and a decrease in competitiveness for products of high value added. The potential of export growth for goods that do not have comparative advantages and for competitive agricultural products - grain and sunflower is estimated.

TL;DR: In this article, a slowing-down and focusing structure (SFS) based on a package of elliptical neutron mirrors has been experimentally verified for the operability of a neutron concentrator design in devices that form and use directed high intensity thermal-neutron beams with elliptical profile channels.
Abstract: An experiment has been prepared and performed to prove the feasibility of creating anisotropic structures in which surfaces of thermal-neutron sinks are formed with the subsequent concentration in selected areas. A device capable of selecting neutrons by the direction in space is based on the effect of neutron reflection from the surface of materials. Experimental confirmation has been obtained for the operability of a neutron concentrator design in devices that form and use directed high-intensity thermal-neutron beams with elliptical-profile channels. The neutron concentrator is made of blocks of profiled-graphite and aluminum plates. The operability of a slowing-down and focusing structure (SFS) based on a package of elliptical neutron mirrors has been experimentally verified. The SFS is able to form oriented thermal-neutron beams from the outgoing flow of reactor neutrons. Silicon single-crystal wafers are used, with which it is possible to obtain distributions of integral neutron fluxes in a reactor to detect the effect of selective thermal-neutron separation. The experiments have been carried out in the GEK-4 channel at the IRT-T reactor of the National Research Tomsk Polytechnic University with an integral neutron flux of (2.30−3.02) × 1017 cm−2. The neutron flux is determined from the change in the electrical resistivity of single-crystal silicon wafers. The effect of the thermal-neutron concentration has been detected both on a block of graphite neutron mirrors and on a block of thin-walled aluminum elliptical mirrors.

TL;DR: In this paper, an approach that allows us to compare an arbitrary set of indices and ratings that characterize the level of socio-economic development of the subjects of the Russian Federation in the space of characteristics of differentiation used in solving regional management problems is presented.
Abstract: As a rule, the source information and methods used for construction of many indices have specifics that allow authors and experts to consider these indexes as original and recommend them for use in solving a number of management tasks. However, a comparative analysis of such indices sometimes shows that despite the peculiar names and methods of calculation, some of them do not have significant statistical differences. This paper presents an approach that allows us to compare an arbitrary set of indices and ratings that characterize the level of socio-economic development of the subjects of the Russian Federation in the space of characteristics of differentiation used in solving regional management problems. The purpose of the study is to identify indexes that do not differ significantly. Eighteen indexes are compared. At the first stage of the study, their correlation analysis is performed. Then the indices are regressed to the basic characteristics of differentiation. The analysis of cosines of angles between indices calculated using beta coefficients of regressions allows us to refine the results of correlation analysis and identify a subset of indices that are not distinguishable in solving regional management problems.

TL;DR: In this article, the authors presented the management systems of distributed situational centers, which aim at developing public administration and regulation by increasing the speed of decision-making. But, the study involved such standard methods as economic analysis, classification, expert assessment, deduction, etc., and the results can serve as a theoretical basis for modifying the existing and planned situational centers in Russia, especially those that will form an integral part of the system.
Abstract: Introduction. A complex system of distributed situational centers is one of the main vectors of the transformation of public administration in Russia. Each region needs additional infrastructure to develop a promising mechanism of multifunctional tools for effective electronic administration and management of socio-economic processes within public and private partnerships. The versatility and exclusivity of this mechanism lie in its large-scale capabilities, which make it possible to engage the most important spheres of the state’s life in detailed monitoring, analysis, forecasting, and strategizing. Study objects and methods. The research featured the management systems of situational centers, which aim at developing public administration and regulation by increasing the speed of decision-making. The study involved such standard methods as economic analysis, classification, expert assessment, deduction, etc. Results and discussion. The results can serve as a theoretical basis for modifying the existing and planned situational centers in Russia, especially those that will form an integral part of the system of distributed situational centers. Taking into account the rapid development of new public administration instruments, it is necessary to bridge the gap between Russia and other countries. Conclusion. Modern realities dictate new approaches in the field of public administration and regulation. That is why the development of situational centers is a strategically important area for creating a centralized system for managing the country. Improving the functionality of such centers will lead to a qualitative improvement in the entire structure of the state apparatus.
