Exploring the relationship between quality of life and the degree of internationalisation of the economy: Evidence from Portugal (2005-2022)

Le résumé fourni par la source

This study explores the complex, bidirectional relationship between internationalisation and quality of life, a topic previously explored mostly from a one-sided perspective. While past research has emphasized how internationalisation can influence well-being, this study address a gap in the literature by also investigating how a country’s quality of life might affect its degree of internationalisation. Using a quantitative approach, the research analyses annual data from 2005 to 2022, focusing on key indicators such as the degree of economic openness, the well-being index, and set of control variables. The methodological framework includes multiple regression models, aiming to identify key determinants and assess the strength and direction of the relationships among variables. The findings show that internationalisation does exert a direct, significant impact on well-being, instead, life expectancy is found to be the primary driver of quality of life. Conversely, quality of life does not appear to directly influence internationalisation, with Gross Domestic Product (GDP) per capita emerging as the most significant explanatory variable. These results suggest that the relationship between internationalisation and quality of life is influenced by underlying economic and structural factors, highlighting the importance of integrated public policies that concurrently advance both social welfare and international economic engagement.
