The impact of R&D on energy consumption: Evidence from nonlinear semi-parametric estimations for selected OECD countries
研究了16个OECD国家1980-2021年间能源相关研发对一次能源消耗的影响，发现研发通过提升能源生产率和清洁技术显著降低能耗，为政策制定者推动可持续能源创新提供参考。
We investigate the influence of energy-related research and development (R&D) on primary energy consumption across 16 OECD countries within a semi-parametric framework spanning the period 1980-2021. In doing so, we propose a novel method for introducing an instrumental variable into the local linear dummy variable estimation method to address endogeneity issues. Our results indicate a significant impact of energy-related R&D on energy consumption, attributed to improved energy productivity, the advancement of clean energy technologies, and heightened energy efficiency. This study contributes to existing literature by illustrating the dynamic and multifaceted nature of the relationship, emphasizing that technological innovation in the energy sector plays a pivotal role in reducing overall energy consumption. The insights from our analysis offer valuable guidance for policymakers committed to fostering sustainable energy innovation and development.
