Two-Stage DEA Model with Shared Inputs for Measuring Efficiency of the Governance in Energy Transition

This study applies two-stage Data Envelopment Analysis (DEA) model with shared inputs to the problem of assessment of results of government support of research, development, and demonstration projects in energy sector in 23 countries in 2010–2018. The performance of governments is evaluated in terms of a positive impact on the growth of the energy efficiency of the national economy and the reduction of its carbon intensity. As intermediate results (outputs of the first and inputs of the second stage), patents in the field of energy are considered. The study reveals most and less efficient countries and indicates the target parameters for improvements in energy efficiency in less efficient countries as policy goals.
