The chapter presents three original empirical contributions aimed at investigating the relationships between ESG performance, firm value, economic-financial solidity and the role of FinTech technologies in SMEs. The first study examines the link between ESG performance and firm value in a sample of listed companies. The second one delves into the impact of ESG integration on firms’ profitability and financial stability. The third contribution focuses on the context of Italian and British SMEs, investigating how the diffusion of FinTech in banking ecosystems influences firms’ ability to derive economic benefit from ESG strategies, to improve the quality and reliability of disclosure and to strengthen the consistency between declarations and sustainable behaviours. The empirical analyses adopt advanced quantitative methodologies, providing measurable evidence for the theoretical hypotheses discussed in the previous chapters. The results confirm the relevance of ESG factors as determinants of resilience and firm value, also highlighting the potential of digital solutions in strengthening SMEs’ credibility with financial operators. The chapter thus contributes to bridging the gap between theory and practice, providing evidence useful for both academic research and managerial application.
