中国広東省の電力スポット市場パイロット実験を分析。部分的な市場自由化でも、石炭火力発電を6.6%削減し、再生可能エネルギーの利用と系統柔軟性を向上させることを、高頻度データと因果推論で実証。ただし、ガス火力や小型石炭火力への依存増加というトレードオフも明らかに。
English
Analyzes China's electricity spot market pilot in Guangdong, showing that partial liberalization reduced coal-fired output by 6.6% and increased renewable utilization and flexibility reserves, using high-frequency unit-level data and causal inference. However, the decarbonization potential was partially offset by increased reliance on gas and small coal units for flexibility.

日本のGX文脈において
日本でも部分的な電力市場改革が検討されているが、本論文は柔軟性確保のための制度的保障の重要性を示唆。SSBJや政策設計において、市場メカニズムと規制のバランスを考慮する必要がある。
In the global GX context
Provides causal evidence that even partial electricity market liberalization can spur clean energy transitions, with implications for global TCFD/ISSB frameworks that consider transition risks. Highlights the need for legislative safeguards to manage flexibility gaps, relevant for developing economies and coal-dependent systems worldwide.

🔬研究者:Methodological contribution: uses causal inference with high-frequency data to isolate market reform effects; valuable for energy transition and policy evaluation researchers.
🏛政策担当者:Demonstrates that incremental market reforms can reduce coal generation and integrate renewables, but policy safeguards are needed to address flexibility trade-offs.
📄 Abstract（原文）
Abstract Can incremental market reforms stimulate clean energy transitions in coal-dependent systems? China's electricity spot market pilot in Guangdong, which is a regulated experiment in partial liberalization, reveals how even limited market exposure can spark systemic transformation. Leveraging quarter-hourly, unit-level generation data, and a novel causal inference approach, we demonstrate that the implementation of market mechanisms decreased coal-fired power output by 6.6% while increasing renewable utilization and system flexibility reserves. The “green spark” originated from two mechanisms: (i) exposing cost structure differences between inflexible coal units and near-zero-marginal-cost renewables and (ii) reducing renewable curtailment through market-driven dispatch. However, the reform's decarbonization potential was partially offset by an increasing dependence on gas-fired and small coal units for flexibility. While partial marketization can drive energy transitions, legislative safeguards are needed to address flexibility gaps. These insights guide developing economies in accelerating renewable adoption through incremental institutional innovation.
