高标准农田建设可以改善生产条件和提升经营价值，很可能对农地流转契约期限产生重要影响。本文基于江西省1176份农户抽样调查数据，实证分析高标准农田建设对农地流转契约期限的影响及其机制。结果表明：高标准农田建设能显著促进农户签订更长期限的契约；高标准农田建设通过推动土地整合、强化服务支撑、促进产能提升激励农户签订更长期限的契约；高标准农田建设对年龄较大、参加了农民合作社、经营规模较大、农地确权的农户的影响更显著。

High-standard farmland construction can improve production conditions and enhance operational value, which is likely to exert a significant impact on the contract duration of farmland transfer. Based on survey data of 1176 farming households in Jiangxi Province, the impact of high-standard farmland construction on the farmland transfer contract duration and its mechanisms have been analyzed empirically. The results show that high-standard farmland construction can significantly prompt farmers to sign longer-term contracts. High-standard farmland construction incentivizes farmers to opt for longer-term contracts by facilitating land consolidation, strengthening service support, and boosting productivity improvement. The impact of high-standard farmland construction is more pronounced on older farmers, those who have joined farmers’ cooperatives, are engaging in larger-scale operations or have confirmed their land through certification.
