| 中文摘要: |
| 为探究农业数字化对耕地利用生态效率的影响及空间效应,本研究基于2011—2022年我国31个省(直辖市、自治区)的面板数据,综合运用固定效应模型、中介效应模型和空间杜宾模型等方法,进行了实证分析与研究。结果表明:农业数字化对耕地利用生态效率具有显著的正向影响,影响系数为0.159,这一结果在经过稳健性检验后依然成立。技术进步在其中发挥中介作用,农业数字化对技术进步的影响系数为0.184,技术进步对耕地利用生态效率的影响系数为0.144。农业数字化对耕地利用生态效率具有正向空间效应,数字化依托区域协同与知识溢出效应促进周边地区耕地利用生态效率的提升。异质性分析结果显示,农业数字化对耕地利用生态效率的影响具有粮食功能区差异和地区差异。因此,本研究建议提升农业数字化发展水平,构建跨区域协作机制,因地制宜制定区域化差异政策,以促进耕地利用生态效率的提升。 |

| To explore the impact of agricultural digitalization on the ecological efficiency of cultivated land use and its spatial effects, this study conducted an empirical analysis based on the panel data of 31 provinces(municipalities, autonomous regions)in China from 2011 to 2022, by employing fixed-effects models, mediation effect models, and spatial Durbin models. The results showed that agricultural digitalization exerted a significantly positive impact on the eco-efficiency of cultivated land use, with an impact coefficient of 0.159, and this result remained valid after robustness tests. Technological progress played a positive mediating role, with agricultural digitalization having an impact coefficient of 0.184 on technological progress and technological progress having an impact coefficient of 0.144 on the ecological efficiency of cultivated land use. Agricultural digitalization had a positive spatial effect on the eco-efficiency of cultivated land use, leveraging regional synergy to boost the eco-efficiency of cultivated land utilization in neighboring areas. Heterogeneity analysis indicated that the impact of agricultural digitalization on the ecological efficiency of cultivated land use varied across grain functional zones and regions. Therefore, it is suggested to enhance the development level of agricultural digitalization, establish cross-regional collaboration mechanisms, and formulate regional differentiated policies according to local conditions, so as to promote the improvement of the ecological efficiency of cultivated land use. |
