This PhD thesis aims to analyze the dynamic relationship between green innovation and entrepreneurship, with a specific focus on three dimensions: (a) the role of Research and Development (R&D) investments, (b) the impact of green technology patents on entrepreneurial activity, and (c) the interconnection between energy markets and green innovation. Investigating these research pillars will contribute to a deeper understanding of the mechanisms linking knowledge production with entrepreneurial exploitation and energy market dynamics. Furthermore, it will provide valuable empirical and theoretical insights into a highly topical field of strategic importance for the economy’s green transition.
