The globalization process and the war in Ukraine show us that migration is one of the strongest global trends in the modern economy. For this paper, we determined three types of migration, depending on the intention of the people involved, these being labor, educational, and refugee migration. Each type has a different influence on the macroeconomic process. However, in this paper, we investigate the influence of general migration on GDP. We analyze five factors that have major influences on GDP, namely, migration (I), interest rate (IR), active population (AP), export (E), and the consumer price index (CPI). For the purposes of this paper, vector autoregressive models (VAR models) were chosen to perform the analysis. We used the Granger causality test to investigate the lag structure and identified the exogenous variables in the VAR model, such as GDP, migration, and the active population. We investigated the cross-influence between these factors and found that migration has a negative effect on the active population and a positive effect on GDP, while GDP growth leads to a decrease in migration. The Akaike and Schwartz criteria showed the high quality of the VAR models. The impulse analysis of shock influences identifies the structure of the reaction seen in GDP and migration, depending on their shock factors. Using decomposition analysis, we found that migration and GDP influence each other by 10–14%, which can improve the forecasting of these factors and the study of structural migration by the use of these three types.

A characteristic feature of the XXI century is the emergence of the digital society phenomenon, which significantly changes all processes in higher education. The implementation of innovations into university activity, creation of its digital culture, and digital environment are the key features of an innovative-active university (IAU) and factors of its development. The paper aims to develop a strategy and innovative-indicative measures for digitalization of IAU activities based on the study of society’s digital maturity. Index, rating, comparative analyzes, and decomposition method were used. It is determined that Ukraine has a significant gap in comparison with the developed countries in terms of digital maturity of society and occupies lower than average positions in international informatization indices. To assess the state of digitalization processes in Ukraine, government measures for the development of digital culture were analyzed, the limitations and triggers of society digitalization are identified. It is proved that the digitalization of education has a dominant impact on the overall level of digital competitiveness. That is, the introduction of information and communication technologies in the IAU activity is an urgent task of its management. The digitalization strategy of S.Kuznets KhNUE in accordance with its educational, scientific and technical, marketing, and international activities was created. The proposed strategy is based on a systemic understanding of digitalization processes, which makes it possible to increase the degree of their controllability. A set of innovative and indicative measures was developed, which constitute the tactical contour of IAU digital process management. AcknowledgmentThe following materials were used in writing this paper: Development of methodological and model-information support for the construction of an innovative type university on the basis of education quality and anti-corruption (state registration number: 0120U102152).

Innovative activity of universities and the formation of entrepreneur universities of the innovative type is one of the forms of integration of the higher education systems of countries into the world educational and scientific space, support of their competitiveness. Based on the separation of interaction between universities and the economy and society, an evolutionary model of the university’s interaction with stakeholders was developed. Understanding the new mission of universities made it possible to separate the dominants of activities of an innovative and active university (IAU), to develop a scheme of the interconnection of management processes and its basic functions. The authors’ interpretation of the IAU and the preconditions for constructing a corporate information and education system (CIES) was formed.Given the synergism and hybridity of modern cyber threats, the rise of corruption in the educational sphere, the Anti-corruption concept, which provides countering the elements of corruption and integrated hybrid threats through the construction of an adaptive information protection system (AIPS). The basis of corruption counteraction is the digital signature (DS) of the Key Certification Center (KCC) based on PKI (Public Key Infrastructure). To ensure the security of information resources (IR) of CIES, we proposed a model that makes it possible not only to take into consideration the synergy and hybridity of modern threats but also to form preventive anti-corruption measures. A model for providing anti-corruption measures that reflects the scenarios of the behavior of the participants of the corruption process and the anti-corruption bodies was developed. This makes it possible to assess the dynamics of the distribution of corruption deals over time and by the types of corruption to ensure the effective distribution of the university resources for anti-corruption activities

The trends in the formation of the digital society are studied, and Ukraine’s readiness to implement digitalization processes is determined. The article is aimed at assessing Ukraine’s position among other states in the digital competitiveness index based on comparative rating analysis, and identifying trends in the development of digitalization in Ukraine’s society and economy. Based on a comparative rating analysis of Ukraine's position in the world as for its digitalization of society and economy, it is determined that Ukraine ranks low in its digital competitiveness as compared to advanced countries, but belongs to the group of promising countries currently characterized by a low digitalization level but tending to increase their pace of digital development. Based on the cluster analysis, countries are grouped into four clusters according to their development of digital processes, and not only Ukraine's place among them is identified, but also cluster migration is analyzed, as well as positive and negative trends in digitalization processes. The general features of information society development, specific for the countries in each individual cluster, are determined. Characteristic features of two scenarios for the digitalization of national society are suggested, i.e. the evolutionary and forced ones, and it is proved that the formation of a developed digital economy in Ukraine requires systematic state support for implementing digital tools in public life, and focus on the forced (target) scenario for digital development processes.

In order to evaluate effectiveness of using a corporate scientific-educational network, we propose to apply an integrated indicator of the quality of services for users of CSES based on the combination of main technical and economic indicators (functional efficiency). The assessment techniques, proposed in the present work, for cryptographic procedures, for the formation of an integrated indicator of threats based on the synergistic approach to assessing the impacts on elements of CES, taken together, make it possible to estimate resistance of the applied cryptographic algorithms in technical systems of information protection within a corporate educational network. The devised procedure for estimating the effectiveness of investment into information security of CSES enables effective control over capital investment into effectiveness of technical solutions for information safety based on the proposed technique for assessing investment into TMIP, which takes into consideration the synergy and hybridization of contemporary threats. The obtained expressions for efficiency of using TMIP (their resistance and implementation based on the method of express-analysis), investment into TMIP (based on the proposed procedure) in the comprehensive indicator of assessment of functional efficiency of a corporate scientific-educational network at different techniques for managing data exchange make it possible to obtain comparative estimates to ensure the required indicators of quality of services when using different protocols for managing CSES data exchange
