Accelerating the pace of energy technological innovation is essential to
curb global climate change and build a clean energy system. Based on
this idea, from the perspective of renewable energy technology gaps
across countries, this study presents a thorough empirical analysis of
the convergence of energy technology research, development, and
demonstration (RD&D) budgets across OECD countries over 1985–2017.
In doing so, we apply two-regimes threshold autoregressive approach
to account for heterogeneity, nonlinearity, and transition path in energy
technology RD&D convergence. One observation is that only a small
number of advanced countries namely Canada, Japan, and the U.S.
follow a nonlinear process and exhibit partial convergence in energy
technology RD&D budgets with Japan as a transition country.
Interestingly, our results also provide clear support for the global
convergence of energy technology RD&D budgets once accounting for
the two regimes jointly. These trends in national energy innovation
policies could arguably help Canada, Japan, and the U.S. to drive up
their energy RD&D trajectory into the future, suggesting that these
countries would be able to achieve a more sustainable energy
innovation supply system.
