The main objective of the paper is to present the development of digital economy and society in the Countries of the European Union in the light of the digital convergence of these markets. The analysis was based on the data on the Digital Economy and Society Index (DESI) from 2015 and 2020. Empirical studies have been conducted in two stages. First, basic measures of time series dynamics were used to determine the dynamics of changes in index values. On the other hand, in order to classify countries in terms of similarity of value and structure of the DESI, a cluster analysis was used as one of the basic methods of the so-called unsupervised statistical grouping. The studies presented confirm that the levels of indicators and the dynamics of changes in their value at the level of the synthetic DESI indicator, and in the five underlying areas of analysis, vary despite the fact that almost all are pro-growth, including for isolated clusters of EU-28 countries. When analyzing the DESI synthetic index and its components, it was concluded that there is generally an increase in convergence between the EU-28 countries in terms of the level of development of the digital economy and society, as well as in four components: Connectivity, Human Capital, Use of Internet Services and Digital Public Services. The Integration of Digital Technology area was the only one where increasing polarization of results was observed. The added value of the paper is to fill the research gap in research on the digital convergence of markets in the Countries of the European Union.

Purpose: The aim of the theoretical deliberations and empirical research conducted is to determine the basic sources of problems in the SME sector of enterprises in Poland during the COVID-19 pandemic crisis, and to present how enterprises are responding to external changes and adapting to these changes. The consideration of four types of enterprise strategies in the context of a large scale and a strong influence of external conditions on their activities is the leitmotif of the undertaken research. Design/methodology/approach: The research work used the analysis of the literature of the subject within the research methods of social studies with respect of the analysis and criticism of literature, as well as for logical analysis and structure. The empirical part applied desk research which concerned quantitative methods in the form of a survey. The survey was conducted among SME sector firms, that is micro-, small-, and medium-sized business entities whose economic activity was registered in Poland. The detailed information on sample sizes (based on three report sources) was given in the methodological part of the article. The research period is related to the COVID-19 pandemic. The statistical data presented in the paper primarily include the period of 2019 and 2020. Findings: The research revealed the basic sources of problems that SMEs in Poland struggled with during the COVID-19 pandemic in the period 2019–2020. The article presents the effects of changes related to the bankruptcy and restructuring processes of enterprises, expressed in an increase in their number in the compared years. In particular, the negative effects of the COVID-19 reality were experienced by SMEs conducting service activities. The paper also shows ways of responding and adapting to the turbulent reality of the studied enterprises, indicating the transformation and adaptation types of the actions taken. Originality/value: The presented research into SMEs is an original combination of theoretical issues related to business management during a crisis and distinguished strategies of responding to changes in the conditions of uncertainty, and the actual picture of changes in those entities in the days of the COVID-19 pandemic. The value of the research is manifested in the uniqueness of linking theoretical references of problems of management studies with respect to organisation management in the strategic aspect to specific research findings in firms defined as the core of the national economy, namely small- and medium-sized enterprises under the conditions of the COVID-19 pandemic crisis.

The article presents the current situation with the implementation of electric cars in Poland against the background of pan-European trends and the current energy sector condition in Poland. The aim of the study was to show the ecological, economic, social, and technical difficulties and controversies related to the use of electric cars in Poland. The authors used statistical analysis and identified the main factors of electromobility development in Poland. Despite the declared electromobility in the Strategy of Responsible Development program, the degree of its implementation is far from the previously established goals. The article analyzes the feasibility of the above plan and indicates the factors inhibiting the development of electromobility in Poland. The strategy and decisions to further implement electric cars cannot be purely political. In justifying the need to promote the use of electric cars in Poland, one should take into account the specificity of the Polish economy, its energy system, the condition of its infrastructure, and real social needs. The authors formulated a hypothesis that the aforementioned program is based on simplistic assumptions and marginalizes or ignores significant barriers to the development of electricity-based transport in Poland. The successful implementation of that program is conditioned by comprehensive and costly activities aimed to transform the whole energy system and introduce an effective system of incentives for the buyers of electric cars.

The energy sector has been a pioneer in the use of information and communication technologies for many years, and has undergone enormous changes in recent years as a result of the transition resulting from the fourth industrial revolution. In the paper, we examine and analyse relevant studies and their findings in order to show the current status of research on three selected aspects of digitalisation in energy sector enterprises. The paper sheds light on the diverse drivers influencing the digitalisation processes of energy sector companies. It also provides an overview of business models that are or will soon be implemented in the energy sector thanks to opportunities offered by digitalisation in response to observed trends in the energy market. Finally, it illustrates open research challenges and future dilemmas related to various aspects of energy sector digitalisation. The paper was prepared using the critical literature review method. It covers a large volume of the most recent and relevant literature referring to the three major research areas mentioned above. The literature review allowed us to identify the drivers influencing the digitalisation of energy companies and distinguish between those specific to this sector and those relating to all businesses as a part of the more general phenomena of Industry 4.0 and Industry 5.0. We also show how the digitalisation-based business model innovation presented in the literature empowers new energy producers and consumers through business models. We have also identified the most frequently indicated challenges and dilemmas in the digitalisation of energy companies related to the risk of the destabilisation of the energy market due to decentralisation, new requirements placed on the competences of energy sector workers, the new culture of interaction between energy suppliers and consumers, and the digital security of data used in the energy system.

The aim of this article is to analyze the effectiveness of the Extended Producer Responsibility (EPR) concept for packaging in the context of the transition to a Circular Economy (CE) and the corresponding transformation of the energy sector. The functioning of today’s packaging industry is becoming more and more linked to the assumptions of the CE due to the use and recycling of raw materials. The basic research method used in this work is an analysis of the literature on the links between the concept of the EPR and the CE. The authors limited their research to the selected legal, economic and social aspects of packaging production and management in the European Union (EU). The situation in Poland is discussed in particular and the legal, economic and social specificity of the implementation of the EPR in this country is presented. This paper emphasizes the dependance between the implementation of the EPR concept and the effectiveness of the transformation toward a CE, which is achieved by increasing the circularity in the energy sector.

This paper discusses the problems connected with visible changes in industry in the context of the consequent four industrial revolutions. The last one is associated with “industry 4.0”, which in turn manifests in the presence of the following constitutive parts (systems): cyber physical systems, the Internet of Things, the Internet of Services and intelligent factories. Another important factor of the ongoing changes is the appearance of a new branch, which tries to comprise in its theoretical divagations the problems discussed in IT, mathematics, neurophysiology, electronics, psychology, anthropology and philosophy. In the experimental area this realm, in turn, is treated as a branch of IT. All these constituents can be defined as artificial intelligence. The aim of this research is an attempt to answer the question posed in the title of the article, taking into consideration the potentially most holistic approach to these problems in the context of sustainable development of the constituent capitals taking into consideration not only the increasing of opportunities but maximizing the benefits in the natural, social and economic spheres.
