Exploring Technological Originality and Self-Citation in Wind Energy Innovation: Implications for Technological Impact

Abstract

Technological innovation is paramount for accelerating climate change mitigation efforts within sectors characterized by low technological diffusion. This study examines the role of self-citation and technological novelty on the technological impact of wind energy technologies (2010–2023). Using USPTO patent data and a negative binomial regression analysis, the results reveal an inverse relationship between self-citation and technological impact and a positive relationship between technological originality and technological impact. Specifically, a 1% increase in the self-citation rate is associated with an 11.2% decrease in technological impact, while a 1% increase in technological originality leads to a 5.2% increase in technological impact. These findings highlight the need for policies that incentivize technological diversity and foster knowledge exchange and collaboration among firms to enhance innovation diffusion. By providing insights into firms’ innovation strategies, this study offers practical guidance for policymakers aiming to accelerate renewable energy adoption and achieve long-term sustainability goals.
