🔬研究者:Offers a standardized framework for factor taxonomy that can improve comparability of energy policy studies.

🏢実務担当者:May help in structuring policy analysis reports and ensuring consistent terminology in sustainability disclosures.

🏛政策担当者:Provides a tool for transparent and comparable policy evaluation across regions, supporting evidence-based decision-making.

Despite the surge in energy policy research, the absence of a standardized vocabulary for analytical factors hinders the comparability of studies and, therefore, the effectiveness of policy design. This study addresses this gap by developing a comprehensive, multidimensional ontology of 190 unique factors extracted from a structured review of 150 high-impact articles published in 2024 and 2025. Factors were organized into 11 functional categories and classified by their analytical roles as inputs, outputs, decisions, or mediating variables. Input and output roles accounted for most factor assignments, representing 44.4% and 36.8%, respectively, while mediating and decision-oriented factors were less frequent. The analysis also identified geographical differences within the reviewed sample. The regional comparison focused on China, Europe, and the Middle East, the three most represented regions in the dataset. Chinese studies more frequently emphasized environmental policy stringency and government intervention, European studies placed greater emphasis on system profitability and capital investment requirements, and Middle Eastern studies highlighted demand flexibility and system profitability. These patterns should be interpreted as descriptive findings within the reviewed sample. Although the short time window limits the ability to infer long-term trends, it allows the ontology to capture recent developments and emerging analytical priorities in energy policy research. This ontology provides a robust, standardized framework that bridges the gap between technical power system modeling and socio-economic policy analysis. By aligning research variables with global sustainability targets, this tool facilitates more transparent decision-making toward sustainable energy systems.
