本研究は、高規格農地整備（HSFC）が気候スマート農業（CSA）に与える多次元的影響を、PSRO枠組みと連続DIDモデルで分析した。湖南省122県の2003〜2022年パネルデータを用い、HSFCはCSA全体に正の効果を持つが、短期的には炭素削減柱に負の影響を与えることを示す。食料安全保障・気候適応と炭素削減の間にトレードオフが存在し、地域条件により効果が異なることを明らかにした。
English
Using a Pressure-State-Response-Objective framework and continuous difference-in-differences on 2003–2022 panel data from 122 counties in Hunan, China, this study examines how high-standard farmland construction (HSFC) affects climate-smart agriculture (CSA). HSFC significantly improves CSA overall, boosting food security and climate adaptation but reducing carbon mitigation in the short term, with heterogeneous regional effects. Gains arise from better production conditions, lower input pressure, and technological and habitat improvements.

日本のGX文脈において
日本のGX文脈では、農地整備・スマート農業を通じた適応策と炭素削減のトレードオフは、農業分野の気候変動適応計画やJ-クレジット（農地土壌炭素貯留）の設計に示唆を与える。食料安全保障と脱炭素の両立は、農林水産省の「みどりの食料システム戦略」とも接続する論点である。
In the global GX context
For global GX scholarship, this paper contributes county-level empirical evidence on how land-consolidation mega-programs can simultaneously advance adaptation and food security while creating short-term carbon mitigation trade-offs—relevant to climate-smart agriculture metrics and to emerging nature/land-sector disclosure under ISSB and CSRD. It highlights the need for multi-pillar CSA indicators that capture synergies and trade-offs rather than single outcomes.
👥 読者別の含意
🔬研究者:農地整備と気候スマート農業の多次元評価にPSRO枠組みと連続DIDを適用した実証手法が参考になる。
🏢実務担当者:農業・食品企業にとって、農地整備投資が適応と炭素削減のトレードオフを生む点をサプライチェーン気候リスク管理に反映する示唆がある。
🏛政策担当者:農地整備政策が食料安全保障と適応を高める一方、短期的な炭素削減に負の影響を与えうる点を政策設計で考慮すべき。
📄 Abstract（原文）
Extreme climate risks and farmland structural constraints are intensifying agricultural vulnerability, making the improvement of climate-smart agriculture (CSA) essential for enhancing agricultural resilience and sustainability. High-standard farmland construction (HSFC) represents an important practice for advancing CSA by improving cultivated land quality and farmland infrastructure. However, existing studies have mainly examined HSFC’s effects on single outcomes, including yield, efficiency, or environmental performance, with insufficient attention to whether it can simultaneously advance multiple CSA objectives or generate synergies and trade-offs among them. To examine the multidimensional linkages between HSFC and CSA, this study proposes an integrated Pressure-State-Response-Objective (PSRO) analytical framework. Using 2003–2022 panel data for 122 counties in Hunan Province, we apply a continuous difference-in-differences (DID) model and mechanism tests to estimate HSFC’s policy effects and assess transmission through input optimization, technology upgrading, and cultivated-land habitat quality. Results show that (1) HSFC has a positive and significant policy effect on CSA, with estimated coefficients of about 0.011–0.012 across specifications; (2) HSFC positively influences CSA in pillars food security and climate adaptation, but negatively affects pillar carbon mitigation in the short term; (3) heterogeneous effects are evident across regions, with stronger impacts where regional development conditions and land-consolidation potential are more favorable; (4) CSA gains from HSFC arise from improved farmland production conditions, reduced per-output input pressure, and complementary technological and cultivated-land habitat improvements. This study links a land-consolidation mega-program with a multi-pillar CSA index under an integrated PSRO framework and offers guidance for coordinating food security, climate resilience, and carbon mitigation.
