中国の745郡のパネルデータを用いて、「ブロードバンド中国」政策が作物生産炭素排出に与える影響を差の差法で分析。産業構造や農村所得、教育水準が重要な経路であることを示し、地域によって効果が異なることを明らかにした。デジタルインフラ投資は低開発地域や主要穀物生産地域でより有効。
English
Using panel data from 745 counties in China, this study applies a staggered difference-in-differences approach to examine the impact of digital infrastructure development (Broadband China policy) on crop production carbon emissions. Findings show that industrial structure, rural household income, and educational attainment are important channels. Decarbonization effects vary across economic regions and grain-production zones, suggesting targeted digital investment.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
本論文は、中国の農業セクターにおけるデジタル化の脱炭素効果を郡レベルで実証した点が新規。日本では農業分野のGX戦略（みどりの食料システム戦略）との関連で、デジタル技術導入の効果を定量的に評価する際の参考となる。
In the global GX context
This paper provides empirical evidence on the digitalization-decarbonization link in agriculture at a fine spatial scale, relevant to global discussions on agricultural climate mitigation and the role of digital infrastructure. The quasi-experimental design and channel analysis offer insights for policymakers in developing and developed countries.

📄 Abstract（原文）
The agricultural sector is a major contributor to global carbon emissions, and reducing emissions from crop production is critical for mitigating greenhouse gases and combating climate change. Digitalization has emerged as a promising strategy for agricultural decarbonization, yet most existing studies focus on the whole agriculture, with limited attention to crop production separately. Moreover, analyses often rely on provincial-level data, overlooking higher-resolution datasets. Using panel data from 745 counties in China, this study employs the 'Broadband China' policy as a quasi-natural experiment and applies a staggered difference-in-differences approach to examine the impact of digital infrastructure development on crop production carbon emissions. The findings hold up under several robustness checks. Further analysis indicates that industrial structure, rural household income, and educational attainment are important channels associated with this effect. The decarbonization effects of digitalization vary across economic regions and grain-production zones. These findings suggest that digital infrastructure development can support greener crop production, although its effects differ across regional contexts. Accordingly, greater investment in digital infrastructure is recommended for less developed regions and major grain-producing areas, whereas more developed regions and grain-consuming areas may require complementary non-digital measures to achieve further emission reductions. Greater investment in digital infrastructure is recommended for less developed regions and major grain-producing areas, whereas more developed regions and grain-consuming areas may require complementary non-digital approaches to achieve emission reductions.
