中国13主要穀倉地帯169都市の2013〜2023年パネルデータを用い、低空経済パイロット政策（LAEPP）を準自然実験としてDID分析した研究。LAEPPは農業炭素排出強度を平均10.327%低下させ、農薬投入の削減と農業労働効率の向上が媒介経路であることを示す。地形起伏が大きく教育水準が高い地域ほど効果が強い。空間スピルオーバーやミクロ経路の未検討が限界として挙げられている。
English
Using panel data from 169 cities in China's 13 major grain-producing areas (2013-2023), this DID study treats the low-altitude economy pilot policy (LAEPP) as a quasi-natural experiment. LAEPP reduces agricultural carbon emission intensity by 10.327% on average, mediated by lower pesticide intensity and higher agricultural labor efficiency, with stronger effects in rugged or better-educated areas. Spatial spillovers and micro-level mechanisms remain unexplored.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
中国の農業炭素削減政策の実証研究であり、日本のSSBJ・有報開示やScope3農業由来排出の議論とは直接接続しない。ただし、政策介入が炭素強度を下げる因果推論手法（DID）は、日本のGX政策評価や地域脱炭素の効果検証に方法論的示唆を与える。
In the global GX context
This adds to the empirical climate-policy literature on how industrial/aviation-adjacent pilot policies can indirectly lower agricultural emission intensity, a pathway rarely covered in TCFD/ISSB disclosure scholarship. It offers a DID template for evaluating place-based decarbonization pilots, though it does not engage disclosure frameworks directly.
👥 読者別の含意
🔬研究者:農業炭素強度に対する政策介入の因果効果をDIDで推定する実証例として、手法と媒介経路の設計を参考にできる。
🏢実務担当者:農業・食品サプライチェーン企業にとって、農薬削減と労働効率改善が排出強度低減に寄与する可能性を示す参考情報となる。
🏛政策担当者:地域パイロット政策が農業排出強度を下げうることを示し、政策評価設計や条件別効果の考慮に資する。
📄 Abstract（原文）
Reducing agricultural carbon emission intensity (ACEI) is of great value for sustainable development. The low-altitude economy (LAE) has a significant impact on ACEI, but existing studies lack systematic theoretical analysis and empirical verification in this regard. Based on theoretical analysis, this study uses China’s nationwide low-altitude airspace management reform pilot policy as the core policy within the low-altitude economy pilot policy (LAEPP) to construct a quasi-natural experiment. It uses panel data for 169 cities in China’s 13 major grain-producing areas (MGPAs) from 2013 to 2023 and applies the difference-in-differences (DID) method to empirically analyze the impact of LAEPP on ACEI. The analysis reveals the following: (1) LAEPP has a significant negative impact on ACEI. On average, LAEPP reduces the ACEI of cities in the treatment group by 10.327% relative to that of the control group. This negative impact remains robust after a series of robustness checks. (2) LAEPP reduces ACEI by reducing pesticide intensity and improving agricultural labor efficiency. (3) The impact of LAEPP on ACEI is heterogeneous. When terrain undulation is greater or the educational level of the population is higher, the negative impact of LAEPP on ACEI is stronger. This study has several limitations. For instance, the spatial spillover effect was not considered; micro-level mechanisms were not explored; and some estimated data were used in the analysis. To promote ACEI reduction, further development of the LAE is recommended.
