Research background: This study identifies the key factors influencing environmental health across a global panel of countries, focusing on protection from environmental hazards, as informed by the existing literature, while also shedding light on novel aspects of these causal relationships. Purpose of the article: This study aims to reveal, through a comprehensive review of the relevant literature, the underexplored phenomena of spatial diffusion and contagion of national environmental behaviors and the nonlinear dynamics between environmental performance and its determinants, acknowledging the significant diversity in the characteristics and behaviors of the countries studied. Methods: Spatial analysis and econometric methods, including spatial panel regression alongside dynamic panel models using threshold techniques, were employed to meet the study’s objectives. Findings & value added: This study’s major finding is that environmental performance across nations shows significant clustering influenced by economic and institutional factors. This clustering effect arises from spatial contagion and diffusion processes, as evidenced by spatial panel regression analysis. Furthermore, this study demonstrates that variations in environmental behavior can be attributed to differing levels of development and specific internal conditions within countries. Notably, a country’s gross domestic product and the proportion of industries in its economy have a substantial effect on its environmental health practices, establishing distinct impact thresholds. This research enriches academic dialogue by illustrating, through these thresholds, that in less developed countries, an increased industrial share leads to environmental degradation. Moreover, the influence of the other examined factors varied depending on the category of the country under review, highlighting the nuanced effects of economic and institutional variables on environmental outcomes.

Ostatnie wyniki prac naukowych zwracają uwagę na rolę zlokalizowanych korzyści skali zarówno dla wzrostu gospodarczego, jak i dla procesów aglomeracyjnych. Badacze chcą wiedzieć, czy korzyści skali są stałe, czy rosną, i jeśli tak, to do jakiego stopnia. Aby odpowiedzieć na te pytania, w niniejszym artykule oszacowany został przestrzenny model ekonometryczny w oparciu o prawo Verdoorna, opisujące zależność wzrostu produktywności od wzrostu produkcji. Celem artykułu jest prezentacja nowych wyników oszacowań stopnia korzyści skali dla regionów UE. Wyniki te wskazują, że hipoteza o rosnących korzyściach skali jest nadal aktualna. Badania zostały przeprowadzone z zastosowaniem modelu WAMP Durbina (wielowymiarowego autoregresyjnego modelu przestrzennego Durbina) z przestrzennymi efektami stałymi. Z analizy wykonanej dla 261 regionów 28 państw UE wynika, że rosnące korzyści skali dla regionów UE są znaczące.

Recent findings emphasise the importance of localised returns to scale for the regional growth as well as for the agglomeration processes. However, it is still not well established whether returns to scale are constant or increasing, and to what extent. Therefore, in this study we apply specification which describes the productivity growth with the growth of output through the Verdoorn’s law. This study aims to provide some new estimates of the degree of returns to scale for EU regions. Our findings show that the hypothesis of increasing returns to scale is still valid in today’s EU economy. To test the hypothesis, we have employed the Multidimensional Spatial Panel Durbin Model with Spatial Fixed Effects. The research is conducted for 261 regions of the EU 28. The paper concludes that increasing returns to scale in EU regions are substantial.
