Abstract
This paper identifies the most influential factors in shaping the climate change competitiveness of the EU regions. We conducted multiple linear regression, geographically weighted regression and polynomial best subset regression analysis to explore the variability in regional competitiveness by economic, environmental, social, innovative and technological factors. The results of the study provide rigorously tested and evidence-based insights into the most instrumental factors shaping climate change competitiveness of the EU regions. The findings revealed that the most affected factors were the number of cooling and heating days, CO emissions, e-banking, digital skills, urbanisation levels and access to technology. On the contrary, the levels of migration and of international scientific publications turned out to be minor. The authors believe that this article highlights several interesting findings and new incentives for further research and discussion regarding regional competitiveness in the face of climate change.
