本研究はOIC加盟45カ国（2015-2021年）の再生可能エネルギー移行効率をDEAウィンドウ法で分析。OICアフリカ諸国が最も安定した効率を示し、アラブ諸国は不安定。非効率の主因は太陽光発電と再生可能エネルギー比率の出力変数にある。
English
This study analyzes renewable energy transition efficiency for 45 OIC countries (2015-2021) using DEA window analysis. OIC-Africa countries show the most stable efficiency, while OIC-Arab countries are the most unstable. The main inefficiency sources are solar energy output and renewable energy share variables.

📄 Abstract（原文）
This study aims to investigate the efficiency of the member countries of the Organization of Islamic Cooperation (OIC) in the transition to renewable energy. Using the Data Envelopment Analysis (DEA) method with a window-based approach, this study analyzes 45 OIC countries during the 2015–2021 period. The Window DEA analysis results show that the level of efficiency stability varied considerably and fluctuated in each window. Based on country groups, it was concluded that the OIC-Africa group is the group of countries with the most stable efficiency levels, followed by the OIC-Asia group, which is in a fairly stable position despite the imbalance in efficiency stability among member countries. The OIC-Arab group is the most unstable group, with highly fluctuating levels of efficiency stability among member countries. Finally, the potential improvement analysis concluded that the largest source of inefficiency came from the output variables, namely solar energy and renewable energy share.
