This article provides a critical study of a New European Bauhaus initiative in the context of transversality, relational nature and sustainability of construction, architecture and civil engineering. Social and environmental factors in this ecosystem of innovation are highlighted, as well as the perspectives of actors within it. The relationships between art, technology and science of historical Bauhaus are assessed. The investigation of transversality was carried out using a visual tool developed by the authors, CATI, considering sustainability as the backbone. The New European Bauhaus is a pool of innovation that is supported by governments, academia, industry, society and the (natural) environment. It aims at social, environmental and cultural sustainability and includes ideas of social transformation. It is necessary to absorb the impact and overwhelming cultural consequences of previous and current Industrial Revolutions, principally relying on cyber–physical systems to generate spaces and collective intelligence. The climate crisis and the COVID-19 pandemic have increased the need for new approaches, expanding the concept of smart cities to smart territories, taking into account participation in society and general inclusivity.

At the European Union (EU) level, innovation matter is acknowledged as crucial for progress and sustainability. Related policy action is materialized through Horizon Europe, the 9th Framework Program (FP) for research and development (R&D). The present 8th FP, Horizon 2020, is already considered the biggest public innovation support program in the world. Accordingly, the 9th FP is a cornerstone of innovation ecosystems configuration in the EU and, thus, should be carefully evaluated. In this paper, the analysis of the forthcoming FP proposal is made and a previously developed framework for the structural advancement assessment of innovation ecosystems was applied. The Actor’s viewpoint from the “innovation helix” is especially advantageous for a thorough evaluation. In conclusion, the Horizon Europe proposal does take into account the knowledge triangle or triple helix (Academia, Government, Industry) with “tacit”, however not very explicit, commitment towards complementing Society and Natural Environment dimensions. The process perspective of innovation is highlighted, particularly in terms of overcoming the “valley of death”; nevertheless, private innovation financing levels are still a matter of concern. If the sustainability is to be achieved, consistently allowing for socioecological transformation, authors recommend the orchestration of efforts, especially in the involvement of Society and implication in innovation, as well as in the Natural Environment orientation.

This integrative review examines the persistent analytical divide in economics by advancing the macro–meso–micro framework as a comprehensive approach for understanding complex socioeconomic ecosystems and sustainability transitions. Drawing on empirical evidence from European energy systems, particularly Greece and the Region of Eastern Macedonia and Thrace, we demonstrate that conventional economic analysis has systematically overlooked the crucial meso-level where evolutionary processes are most visible and transformative. This conceptual “myopia” has led to fragmented policy interventions that work at cross-purposes across different analytical levels. By reconceptualizing economic systems as evolving rule populations operating simultaneously at three distinct but interconnected levels, this view offers diagnostic potential for effective adaptation to sustainability transitions. The framework’s greatest contribution lies in its theoretical thoroughness and, most importantly, in its practical capacity to generate more coherent interventions that harness evolutionary dynamics.

Innovation Ecosystems in the European Union: Towards a Theoretical Framework for their Structural Advancement Assessment

The work aims to analyse how virtual tourism viability is achieved in face of post- pandemic reality stemming from financial economic flows for companies in the sector. The analysis is based on surveys from organisations such as MCI Spain and EventoPlus as well as information obtained from ten professional congresses on health, research as well as corporate topics. Five of these are face-to-face (pre-pandemic), four are virtual and one is hybrid (post-pandemic). The results show that virtual events viability is mainly achieved by sustainability, security, audio-visual elements, and types of event formats. The main conclusion is that the post-pandemic reality demands from congress tourism the creation of new, smart and sustainable ideas to improve the overall satisfaction of value chain participants.

The research objective is to identify clusters of European Union member states similar in terms of electricity generation from renewable energy sources between 2004 and 2023. The diversification of renewable energy sources across the European Union member states was evaluated and juxtaposed dynamically using multivariate comparative analysis methods. Four groups of similar countries were distinguished. The results have confirmed the research hypothesis that most clusters of the European Union member states are similar in electricity generation from renewable energy sources after the accession, including countries that joined the organisation both before and after 2004. The study improves the state of the art regarding the classification and clustering of member states regarding electricity generation from renewable energy sources over two decades following the most significant enlargement. The novelty lies in the new time framework, which covers all years from 2004 to 2023.
