The paper aims to analyse the changing economic structure and the trends of the digitalization amplification through the prism of a dynamic multi-criteria model, assessing the strategic perspective by pivoting digitalization in the strategic equation. The main objectives of the research cover the context of vulnerability across the EUSDR countries, the solutions from the literature review and the definition, testing and implementing of a new dedicated model. The model takes into account regional indicators, reported by Eurostat. Statistical analysis procedures and methods were applied in order to capture the expected disparities under the impact of the pandemic, as well as harmonization with European Strategy for Danube Region (EUSDR) – specific impact indicators. The analysis uses la latest official statistical data from Eurostat. The importance of this scientific approach lies in the fact that the results are applicable to the wider region, the vast majority of the Danube states being EU members (9 states), 3 candidate states and 2 potential candidate states in the new geo-political and military context. States that are not yet EU members have regional and cross-border cooperation agreements with the EU. Moreover, the region itself has reacted in a unified way to the challenges of the economic and pandemic crises, the study being conducted over the period 2004–2020. In addition, EU Member States have additionally benefited from European emergency allocations to counter the effects of the global economic crisis and stem the spread of the pandemic. We used empirical and analytical methods, starting with the study of literature, data collection and consolidation of the database, its homogeneity and the application of modelling procedures. The major key findings are focused on the existence of a strong connection between investment effort, labour skills, sustainable development and the digital economy able to face new global and regional challenges. The policy implication of this research consist in offering viable elements capable of assisting regional decision-makers in adopting topical measures on digitisation and reconfiguring strategic regional connections to maintain a sustainable direction for the EUSDR. The recommendations from this study imbraca forma some directions for action related to labour high skills, digitalization, R&D investment and e-commerce.

The recent COVID-19 crisis, as well as the resulting international response, have demonstrated the importance of medical innovation in meeting current and future health challenges. Yet capacity for innovation differs from country to country, and policymakers are wise to find ways to increase each nation’s ability to generate new solutions. This study examines medical innovation, measured as patents per capita, for 27 EU countries from 2004 to 2018. Modelling innovation as a function of international and domestic macroeconomic variables, government and private-sector R&D, the rate of return to physical and human capital, and a measure of risk, a dynamic panel analysis finds that real-exchange-rate volatility reduces patent applications for some countries, particularly in Central and Eastern Europe. The response to the explanatory variables differs by countries’ overall innovation levels, with innovation in weaker innovators reduced by risk and increased by higher education levels. In stronger innovators, the internal rate of return most strongly drives innovation, suggesting that this process more closely resembles “traditional” investments.

Ecological efficiency (EE) provides much reference for formulating appropriate regional economic, social and environmental policies to promote sustainable development. Interactive subsystems of economy, society and environment within EE system have been considered in this paper. By innovatively integrating the merits of two advanced economic research methods (global super efficiency network data envelopment analysis (GSE-NDEA) and panel vector autoregression (PVAR) and updating the EE evaluation indicator system by following the new features of sustainable development in the recent China, this paper comprehensively evaluates EE by drawing evidence from 3 regions in China during the period of 2011–2020, and further reveals how the three subsystems within EE system interact to achieve EE enhancement. The findings show EE and its three subsystems’ trend, the major constrains of EE development, the regional discrepancies in EE progress, and the interactions among the subsystems of economy-society-environment within the EE system in different regions of China. The policy implications are proposed accordingly.

The debate on the presence of economic benefits in the European Union (EU) is not over. The study responds unequivocally to this question, with the intensity of economic development in the countries that joined the European Union in 2004 and beyond twice as high as that of the countries that joined it this year, i.e. the EU’s old ones compared to the new ones; smoothness – 1.1 times and dynamics – 1.6 times. Another important trend for further development is that, as the level of economic development increases, its smoothness is diminishing. In respect of the context of the EP of all EU Members, it turned out that the higher intensity of enlargement was characterised by higher economic levels, with similar homogeneity and almost identical values for the dynamic indicator. The introduction to the article presents the context of the studies, i.e. two groups of EU Community countries are formed according to their level of economic development and the year of their accession to the Community, as well as a survey scheme. The literature review reveals the methods used to analyse the convergence of economic development in these countries, as members of the Community. The research methodology introduces the indicator of economic development of countries and provides a methodology for assessing its dynamics. The empirical part assesses the dynamics of economic development of both groups of countries and identifies trends in terms of convergence. The discussion section summarises the consolidation and destabilising factors in the EU and the importance of the study carried out in this context. The conclusions present the main results of the studies and outline their further directions. The results of the study can be used both in the EU and for the purpose-oriented decisions of its members on further economic development.

The design of the packages of products/services to be offered by a telecom company to its clients is a complex decision-making process that must consider different criteria to achieve both customer satisfaction and optimization of the company’s resources. In this process, Intuitionistic Fuzzy Sets (IFSs) can be used to manage uncertainty and better represent both preferences and non-preferences expressed by people who value each proposed alternative. We present a novel approach to design/develop new products/services that combines the Lean Six Sigma methodology with IFSs. Its main contribution comes from considering both preferences and nonpreferences expressed by real clients, whereas existing proposals only consider their preferences. By also considering their non-preferences, it provides an additional capacity to manage the high uncertainty in the selection of the commercial plan that best suits each client’s needs. Thus, client satisfaction is increased while improving the company’s corporate image, which will lead to customer loyalty and increased revenue. To validate the presented proposal, it has been applied to a real case study of the telecom sector, in which 2135 users have participated. The results obtained have been analysed and compared with those obtained with a model that does not consider the non-preferences expressed by users.

Classical, neoclassical, institutional and other schools have debated what is crucial for economic growth. Literature review related to economic growth models is extensive. The objective of our paper is to construct a model of economic growth determinants in EU countries, with focus on construction. Our model includes determinants that reflect the impact of construction on economic growth, which is the contribution to existing literature. It has been created for three groups of countries: EU28, old EU and new EU countries. We believe that this has improved the quality of the results and enabled a comparative analysis of the old and new EU countries. In order to create a model, we used a strongly balanced panel of 28 EU countries in the period 1995–2019 and employed the difference-in-differences approach. Our results for EU28 confirm positive effect of industry, gross fixed capital formation, production in construction and cost construction index on GDP, while gross wages are statistically insignificant. FDIs have low negative impact on economic growth in EU28 and old EU, but statistically insignificant in new EU countries. CO2 is significant and positively correlated with economic growth in all countries. Based on empirical results, we propose policy relevance in concluding remarks.

The growing complexity and intertwining of different socio-economic issues both in individual countries and internationally mean that single-theme analyses do not consider all the relationships and thus have cognitive limitations. Therefore, studies that combine several research areas are increasingly common in the literature to clarify the connections and relationships. In this study, considering the sequential nature of the stages, a combined analysis of eco-efficiency, eco-innovation, and Sustainable Development Goals (SDGs) was performed. The analysis was carried out for 27 European Union countries in 2017–2019. Dynamic Network SBM and Dynamic Divisional Malmquist Index were used for the study. The research results show that the EU countries achieve relatively higher efficiency results in eco-innovation and SDG than ecoefficiency. The average overall efficiency level for all EU countries was only 0.63. The change in productivity was influenced by both the frontier shift and catch-up effect, but only with regard to eco-efficiency and eco-innovation. At the same time, the frontier-shift effect did not affect the change in SDG productivity.

The ongoing COVID-19 pandemic put further pressure on the economies, both at individual and global level and, amid already existing vulnerabilities, worsened the economic prospects. As a result of the negative effects of these tensions in tandem with global value chains disruptions, commodities’ prices increased, leading to strong inflationary pressures around the globe. Given possible permanent effects on inflation expectations, it is therefore questionable how fast those prices are to be stabilized. In this context, this paper focuses on a group of 10 European countries, namely Czechia, Hungary, Poland, Romania, France, Germany, Italy, Spain, the Netherlands and the United Kingdom, in the period spanning from 2005 to 2020. By implementing a GVAR model, the study analyses the pass-through of the external shocks stemming mainly from the Euro Area and the US to the CEE region, comparing the responses obtained for these countries with the ones of the developed economies. Considering the strong trade relationships between the analysed countries, the considered transmission channel is the commercial one. The results indicate that a supply shock in the Euro Area has a significant negative impact on the selected CEE countries’ economic growth, the offsetting factors not being strong enough to diminish the response.

With the rapid growth of the solar photovoltaic (PV) market, many distributed PV power projects are introduced to the market. Selecting a rational project investment portfolio is a complex and challenging task for energy enterprises as both financial and non-financial factors of projects are needed to be considered under limited information and resources. This study presents a two-stage hybrid multi-attribute decision-making and integer programming model for distributed PV project portfolio selection. In Stage I, a multiple attribute group decision-making method based on mathematical programming is used to evaluate the non-financial value of projects under incomplete preference information. Compensative weighted averaging operators with an adjustable parameter are utilized to capture the subjective attitudinal character of an expert in the aggregation process. Then, a rank acceptability index is developed to measure each project’s group support degree in non-financial dimension. In Stage II, a bi-objective integer programming model is constructed to optimize project portfolios, which considers both financial and non-financial values of projects under resource, carbon emission and other strategic constraints. The applicability and effectivity of the proposed approach are demonstrated by a case study of a distributed PV project portfolio selection.

Employee job satisfaction is essential for organizations because it influences motivation as well as productivity, and consequently the overall performance of an organization. As the COVID-19 pandemic disrupted many work-related processes and practices, the Industry 5.0 framework formulated new approaches for a sustainable and resilient European industry. The aim of this study is to evaluate the effects of the pandemic on job satisfaction in terms of gender differences and firm size in the context of the Industry 5.0 paradigm. Job Satisfaction Surveys (JSS) from the year 2013 to 2021 were analyzed. Our results indicate that in the Czech Republic, overall job satisfaction did not decline during the pandemic, and women were slightly more satisfied than men. Moreover, overall job satisfaction was slightly higher in small firms. These are surprising results, given the negative impacts on employment reported by many countries. We explore the differences in government policies and programs enacted during the pandemic to assist employers and employees to mitigate the negative impacts of the pandemic. In general, Czech and EU policies appeared to be better in mitigating unemployment rates than US policies.

Sokolová, Vaclav Zubr, Hana Mohelská","doi":"10.3846/tede.2022.17680","DOIUrl":"https://doi.org/10.3846/tede.2022.17680","url":null,"abstract":"Employee job satisfaction is essential for organizations because it influences motivation as well as productivity, and consequently the overall performance of an organization. As the COVID-19 pandemic disrupted many work-related processes and practices, the Industry 5.0 framework formulated new approaches for a sustainable and resilient European industry. The aim of this study is to evaluate the effects of the pandemic on job satisfaction in terms of gender differences and firm size in the context of the Industry 5.0 paradigm. Job Satisfaction Surveys (JSS) from the year 2013 to 2021 were analyzed. Our results indicate that in the Czech Republic, overall job satisfaction did not decline during the pandemic, and women were slightly more satisfied than men. Moreover, overall job satisfaction was slightly higher in small firms. These are surprising results, given the negative impacts on employment reported by many countries. We explore the differences in government policies and programs enacted during the pandemic to assist employers and employees to mitigate the negative impacts of the pandemic. In general, Czech and EU policies appeared to be better in mitigating unemployment rates than US policies. The findings are valuable for crafting best practices for organizations and future policy and program planning for governments.","PeriodicalId":51460,"journal":{"name":"Technological and Economic Development of Economy","volume":"8 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2022-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84627798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
