本研究は、中国の環境規制が炭素強度（GDP当たりCO2排出量）を有意に削減することを、2010〜2023年の主要11カ国のパネルデータとDID-MTP法を用いて実証した。効果は時間とともに強まり、エネルギー強度の低下と技術革新の促進が経路であることを示す。規制と革新・効率性のインセンティブを組み合わせた政策設計の重要性を強調する。
English
This study empirically demonstrates that China's environmental regulations significantly reduce carbon intensity (CO2 per GDP) using panel data from 11 major emitters (2010-2023) and a DID-MTP approach. The effect strengthens over time, operating through reduced energy intensity and increased technological innovation. It highlights the importance of combining environmental enforcement with innovation and efficiency incentives.

📄 Abstract（原文）
Achieving substantial carbon reduction remains a critical challenge for both industrialised and emerging economies. While environmental regulations are widely promoted as an effective policy instrument to reduce emissions, empirical evidence on their national-level impact remains mixed, and the mechanisms through which regulation operates are not fully understood. This research examines whether environmental regulation reduces carbon intensity in China and investigates the channels (e.g., energy intensity and technological innovation) through which this effect occurs. We first used regulatory frequency analysis for the themes of “Innovation”, “Renewable Energy”, and “CO 2 Intensity” between 1996 and 2025 to provide qualitative validation of regulatory evolution consistent with the hypothesised mechanisms. We then use a balanced panel of 11 major CO 2 -emitting countries from 2010 to 2023, we apply a Difference-in-Differences with Multiple Time Periods (DID-MTP) approach, treating China as the intervention case and the remaining countries as comparison units. Carbon intensity is measured as CO 2 emissions relative to GDP, energy intensity is proxied by total energy consumption per unit of GDP, and technological innovation is captured by per-capita trademark registrations. The results indicate that environmental regulations are associated with statistically significant reductions in carbon intensity, with the effect strengthening over time. Further analyses suggest that the reductions are achieved through declining energy intensity and increased technological innovation. Robustness checks confirm the stability of these findings. This study offers new empirical evidence that environmental regulation can be effective drivers of low-carbon transition by promoting innovation and energy efficiency. Our findings highlight the importance of regulatory designs that combine environmental enforcement with incentives for innovation and improvements in energy efficiency.
