◇ 英文摘要
It is crucial to address farmland abandonment to achieve Zero Hunger according to the United Nations’ sustainable development goals. However, quantitative research on this topic is relatively lacking. Based on a large sample of panel data from the Chinese Family Database, this study applies a panel Tobit model to examine the relationship between new agricultural operating entities (NAOEs) and farmland abandonment. The results show that NAOEs—professional operators, family farms, and agricultural cooperatives—are negatively and significantly associated with the ratio of abandoned farmland areas. This effect is achieved through channels such as promoting land leasing, providing technical guidance, and facilitating the sale of agricultural products. Additionally, NAOEs benefit more from China's central and western regions, mountainous areas, villages with better land tenure security, and households with poorer human resource endowments. These findings provide valuable insights for policymakers to ensure food security and promote sustainable development by cultivating various large-scale farming entities.
◇ 中文摘要
根据联合国的可持续发展目标（SDGs），解决撂荒问题对于实现零饥饿目标至关重要。然而，关于这一主题的定量研究却相对缺乏。鉴于此，本文基于中国家庭大数据库的大样本面板数据，利用面板Tobit模型，实证检验了新型农业经营主体与耕地撂荒的关系。研究结果显示，新型农业经营主体与农户耕地撂荒比率负向相关，特别是在专业大户、家庭农场和农民合作社三类新型农业经营主体中，这种效应更为突出。且该效应是主要是通过促进土地流转、提供技术指导、便利农产品销售等渠道实现的。此外，中国的中西部地区、山区、土地产权安全性较好的村庄和人力资源禀赋较差的家庭更能从新型农业经营主体中受益。这些研究发现为决策者通过培育各类新型农业经营主体来保障粮食安全和促进可持续发展提供了宝贵的见解。
该项研究成果的早期版本曾经在2023全球粮食安全青年科学家论坛（The 2023 Global Food Security Forum for Young Scientists2023）以及浙江大学公共管理学院第五届学术年会进行交流，并收到同行专家及与会者的改进建议，作者在这里向他（她）们表达最诚挚的谢意。
据悉，郑淋议副研究员长期深耕农村土地与城乡发展领域，近年来已相继从要素、组织和制度等视角出发，围绕耕地撂荒展开多项研究，相关研究成果见诸Food Policy、Canadian Journal of Agricultural Economics、China Agricultural Economic Review、《中国人口·资源与环境》和《地理研究》等国内外学术期刊。
