The reforms resulted in successful installation of quite advanced infrastructure of digital government. By E-government development index Russia is now in the group of very-high performing countries. Other ratings did not show the same success of the country in other areas of economy, governance and political life. Although digitalization enhances accountability, efficiency and transparency of government, help to reduce costs and lead to better governance, there are examples when countries do not reach these goals despite the implementation of digital technologies. An important part of it is poorly designed strategy of reforms. Particularly, the case when the indicators of achievement the goals of digitalization do not conform closely to what is widely thought to be the modern digital government. In this case even actual accomplishment of the targeted values cannot testify existence of a working e-government. The objectives of this research are to analyze the system of indicators that the Russian government set for the digital reform and to compare this system to international evaluation systems and theoretical background. The research question is whether the indicators that government set can really show the transformation to the digital government. Using analysis of e-government objectives and indicators stated in the adopted legislative acts and their relation with international digital and e-government common goals and the indicators the authors have tried to analyze the reasons why successful performance in e-government reforms in Russia did not lead to new quality of governance. The analysis showed that the system of evaluation of e-government does not meet the requirements and even the proper values of all the indicators will not help to implement real digitalization.","PeriodicalId":368926,"journal":{"name":"Proceedings of the 2019 International SPBPU Scientific Conference on Innovations in Digital Economy","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114238004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the study is to determine the role of factors of innovative development in the Russian economy. The study is based on a systematic approach using statistical analysis methods. In the process of analysis of the methodological provisions of innovative development numerous problems were identified: the complexity of the implementation of the contract for innovation; public funds reduce the lack of capital, but increase the corruption component; the effectiveness of R&D costs is determined by not always affordable education; competition reduces incentives for innovation by reducing monopoly rents, etc. But the need to increase productivity and the prospects for monopolization of individual markets, including through the \"targeted licensing\" of technologies, contribute to the upward trend of innovative development of both individual firms (corporations) and countries as a whole. The analysis of the factors of innovative development of the Russian economy includes the assessment of the dynamics of gross domestic expenditure on R&D, including the expenses of organizations on R&D by sources of financing and sectors of activity. The results of the analysis of the dynamics of R&D expenditures showed stable growth in the public sector and entrepreneurship. The Russian public sector for the development of entrepreneurship in multiples supports the cost of R&D of commercial enterprises. The results of the comparison of Russian GERD with Germany, Japan, the USA and China show the inability of the Russian public sector, commercial enterprises and the government to manage the costs of R&D. The assessment of the factors of innovative development of the Russian economy revealed a significant state impact on the cost structure of R&D. It is revealed that the further innovative development of the Russian economy is not possible without reducing the influence of the public sector and the growth of external technologies and investments, through the intensification of trade with China.","PeriodicalId":368926,"journal":{"name":"Proceedings of the 2019 International SPBPU Scientific Conference on Innovations in Digital Economy","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130731873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present-day pace of life features an intensive renewal of social, economic, and political processes, and such distinctive features, typical for the young generation, as mobility and intensive learning capabilities, help young people to get accustomed to the present-day environment, to get integrated into the structure of social relations and organizational changes. Digital technologies become vital for the educational environment as they help to adjust to these transformations and to boost this breakthrough by fulfilling the functions of reproduction, innovation, and transmission.These issues were brought up within the framework of a sociological survey, launched at several Moscow institutions of higher education.

Digital economics drastically changes all stages of the activities of an enterprise from production management to its relationship with the state. As is well known, digital economics is characterized by the formation of economic models implemented in a software product that allows you to manage the activities of the enterprise continuously and to minimize the costs and risks of non-receipt of profit. The purpose of this study is to form an innovative model based on key aspects for assessing the efficient management of the renewal and use of fixed assets in the digital economy. In order to achieve this goal, we first had to clarify the classification of fixed assets, which allows us to think that the developed innovative model corresponds to the concept and technology of digital economics. Based on this clarified classification of fixed assets, we developed an innovative model for assessing the efficient management of the renewal and use of fixed assets in the digital economy. This model is a comprehensive assessment of the efficient management of the renewal and use of fixed assets. The following methods were used in the research: situational, dynamic analysis, correlation and regression analysis, the method of constructing a normative system of indicators, the method of trend extrapolation, tabular and graphical interpretation of empirical and factual information. The developed innovative model for assessing the efficient management of the renewal and use of fixed assets can be applied in enterprises in sectors of the economy.","PeriodicalId":368926,"journal":{"name":"Proceedings of the 2019 International SPBPU Scientific Conference on Innovations in Digital Economy","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129700413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Structural changes reflect shifts in communicative environments and information fields. The article analyzes the data of a sociological survey of Peter the Great SPbPU students, revealing a positive attitude of students to the process of digitalization. The problem of identifying the accompanying contradictory moments of transformation of the educational space is noted. As a baseline vulnerability, based on surveys, there was a lack of student readiness to increase the share of independent learning and to change the role of the teacher. The conclusion is made in favor of the development of nonlinear educational models and trends that implement a flexible dynamic approach to the educational environment in response to the action of factors - rising students' expectations and high market demands.","PeriodicalId":368926,"journal":{"name":"Proceedings of the 2019 International SPBPU Scientific Conference on Innovations in Digital Economy","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120904854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Assessment of the synergistic effect from solvency changes in M&A transactions based on a dynamic model","authors":"A. Tikhomirov, O. Kalchenko, T. Bogacheva","doi":"10.1145/3372177.3373282","DOIUrl":"https://doi.org/10.1145/3372177.3373282","url":null,"abstract":"The main goal of most merger and acquisition (M&A) transactions is to achieve a synergistic effect. This study proposes a method and a model for predicting the consequences of merger and acquisition transactions from the perspective of achieving synergy. The authors consider the possibility of obtaining a synergistic effect in mergers/acquisitions, which originates from a negative correlation between the liquidity flows passing through companies participating in an M&A transaction. This effect can be determined and assessed using a model that describes a company's cash flows as a Wiener process coming out of a point with a certain liquidity cushion L0. Increments in the company's liquidity cushion at each subsequent stage are viewed as independent random values (positive or negative) governed by the normal law of distribution. Each subsequent liquidity cushion value meets the conditions of the Markov process. Solvency is assessed using a dynamic index TX -- the time during which the probability of losing the liquidity cushion for the company will not exceed X%. For each individual company, the TX value depends on the parameters of the liquidity flow -- L0, mean value μ, and standard deviation σ. Upon conclusion of M&A transactions, the flows are combined. Calculations performed using simulation modeling based on the proposed model show that the TX indicator of the combined company is determined not only by the values of L0, μ,and σ of the M&A participants, but also by the pair correlation coefficient of cash flows ρ. It is found that with the reduction of the correlation coefficient ρ the solvency of the combined company within the framework of the proposed approach increases, reaching its maximum with the correlation coefficient ρ = -1. In addition, by reducing correlation between the flows it is possible to achieve a significant saving of the amount of liquid funds through the reduction of its initial value L0. Another important aspect is the possibility of preliminary quantitative assessment of the synergistic effect. The findings of the study are confirmed only by calculations based on hypothetical models, although they use liquidity flow parameters of actual Russian companies.","PeriodicalId":368926,"journal":{"name":"Proceedings of the 2019 International SPBPU Scientific Conference on Innovations in Digital Economy","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124836228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study is of immediate interest to identify potential risks to the transition of Russia's regions to a digital economy. It makes its objective to determine the levels of preparedness and overall capability in regions that would allow for their transition to a digital economy in the course of establishing and developing the regional systems of sustainable production and consumption. Moreover, structuralizing the strengths and weaknesses of the region during its transition is another area of interest to the research. The paper relies on the content analysis of the statutes and regulations governing the transition of Russia's regions to a digital economy and on the study of their implementation to elicit the major consequences of such a transition for the regional systems of production and consumption in terms of their sustainability, to shed light on prospects for sustainable production and consumption in Russia's regions during their transition to a digital economy and to formulate recommendations for the development of sustainable production and consumption against this background. The analysis has revealed that despite the overall positive impact of the digitalization of Russia's regional economies on the sustainability of regional systems of production and consumption manifested in a reduction in the ecological footprint of consumption, the improved quality of management decisions, the enhanced environmental quality of public purchases, there are considerable risks associated with a decline in lifestyle sustainability, a change in the morphological waste composition of production and consumption as well as a slowdown in the decreasing trend in the energy intensity of the economy[24].","PeriodicalId":368926,"journal":{"name":"Proceedings of the 2019 International SPBPU Scientific Conference on Innovations in Digital Economy","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127921706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result of the analysis, a number of reasons for the inconsistency of Russia's indicators with global trends in socio-economic development and measures that could improve the situation are considered. For research, the method of correlation and regression analysis was chosen, in which regression was used to assess global trends according to the International Monetary Fund, and for the direct analysis of the data obtained, the correlation dependence of the studied phenomena was used. As a result, a number of measures were proposed to improve the socio-economic condition of the Russian regions, thanks to which the conditions for sustainable balanced development will be formulated for the regions.
