题名：Cooperative Quality Improvement Policy and Farmland Abandonment: Evidence from a Difference-in-Differences Analysis Based on Chinese Geospatial Data

期刊：《Land》 2026 15(8).

Abstract: Farmland abandonment has become an increasingly important challenge for the sustainable use of cultivated land worldwide. Although agricultural cooperatives can help mitigate farmland abandonment, their effectiveness has historically been limited in China due to their relatively weak organizational capacity and irregular development. This study argues that the County-wide Cooperative Quality Improvement Policy (CCQIP) improves the operational performance of agricultural cooperatives, thereby strengthening their capacity to mitigate farmland abandonment. Using geospatial data, we identify farmland abandonment at the county level in China and develop and test an analytical framework based on two mechanisms: increasing agricultural returns and improving service provision. The results show that the CCQIP significantly reduces the area of farmland abandonment. This effect is primarily achieved through three channels: promoting agricultural product branding, increasing the use of agricultural socialized services, and enhancing the vitality of the farmland transfer market. Heterogeneity analysis further indicates that the policy has stronger effects in major grain-producing regions and in rice-dominant areas. Furthermore, the inhibitory effect of the CCQIP on farmland abandonment becomes stronger as the region’s comparative advantage in agriculture increases.

摘要：耕地撂荒已成为全球范围内耕地可持续利用面临的一个日益严峻的挑战。尽管农业合作社有助于缓解耕地撂荒问题，但由于其组织化能力相对薄弱、发展不规范，其在中国的作用长期以来受到限制。本研究认为，县级合作社质量提升政策（CCQIP）能够改善农业合作社的经营绩效，从而增强其缓解耕地撂荒的能力。本研究利用地理空间数据，识别了中国县级层面的耕地撂荒情况，并基于两种机制——提高农业收益和改善服务供给——构建并检验了一个分析框架。结果表明，CCQIP显著减少了耕地撂荒面积，其作用主要通过三个渠道实现：促进农产品品牌建设、增加农业社会化服务的使用，以及增强农地流转市场的活力。异质性分析进一步表明，该政策在主要产粮区和以水稻种植为主的地区效果更为显著。此外，随着区域农业比较优势的提升，CCQIP对耕地撂荒的抑制作用也进一步增强。
