摘要：The six GCC states share similar economic, geographic and socio-cultural characteristics and also
face with similar challenges in terms of energy perspective. This study plans to focus on the economic
and energy efficiency of the six GCC states. In the process, the study ranks the GCC states
in terms of their efficiency scores. These efficiencies are computed through Data Envelopment
Analysis. The economic efficiency is calculated for all six GCC states. Capital and labor are the
inputs and GDP is the output. In this survey, Saudi Arabia maintains the highest efficiency score
of 0.94, closely followed by Qatar (0.92), Kuwait (0.89), Bahrain (0.83), Oman (0.81) and UAE
(0.67). There is a huge gap between the economic efficiency scores of Saudi Arabia and UAE. The
environmental efficiency scores are calculated using CO2 emissions as output and electric power
consumption and energy as input. Again, the highest efficiency score is for Saudi Arabia (0.91)
followed by Oman (0.87), Kuwait and Bahrain have a tie for the 3rd position with a score of 0.74.
Finally, the laggards are UAE (0.65) and Qatar (0.62). Again, there is a huge gap between the best
and the worst performers. The case of two countries is worth mentioning. Qatar is ranked second
in terms of economic efficiency while it was ranked sixth in terms of economic efficiency. Oman
was ranked fifth in terms of economic efficiency while it was ranked second in terms of environmental
efficiency. Finally, an average of economic and environmental efficiency are taken to compute
the composite index. Saudi Arabia has the first place followed by Oman, Kuwait, Bahrain,
Qatar and UAE.
