不同模式农地整治对耕地细碎化的影响效应 及其区域差异 ——来自湖北省江汉平原与武陵山区的经验证据

研究目的：基于湖北省江汉平原、武陵山区483份农户调查数据，分析不同模式农地整治对耕地细碎化的影响效应及其区域差异，探求适应现代农业发展的耕地细碎化治理新路径。研究方法：综合指数法、双重差分模型。研究结果：（1）政府主导模式和新农主导模式通过促进地块集中连片的土地平整工程，改善农业生产关系的权属调整工作，共同降低自然因素和产权因素造成的耕地细碎化；（2）相对于政府主导模式，新农主导模式定位于现代农业发展，农地流转与农地整治的耦合度更高，土地平整工程和权属调整的比例更高，对耕地细碎化的治理效果也更为明显；（3）与丘陵山区农地整治相比，平原地区农地整治更能显著降低耕地细碎化。研究结论：建议继续大力实施政府主导模式和新农主导模式的农地整治，结合区域自然资源禀赋、产业布局、区位优势，总结和完善农地整治的地域模式，因地制宜地推进土地平整工程和权属调整工作，全面促进现代农业高质量发展。

Impacts of Different Modes of Rural Land Consolidation on Cultivated Land Fragmentation and Its Regional Differences: Empirical Evidence from Jianghan Plain and Wuling Mountain Area in Hubei Province

The purpose of this study is to explain the impacts of different modes of rural land consolidation on cultivated land fragmentation and its regional differences, based on the survey data of 483 farmers in Jianghan Plain and Wuling Mountain area in Hubei Province, in order to explore the new path of reducing cultivated land fragmentation which adapts to the development of modern agriculture. Difference-in-differences model and comprehensive index method were employed in this study. The results showed that: 1) the government-led mode and the new entities-led mode reduced the natural fragmentation and property fragmentation by land leveling project which could promote the centralized plots of rural land and property rights adjustment which could improve agricultural production relations. 2) The new entities-led mode was oriented at the development of modern agriculture and combined rural land consolidation with rural land transfer, exhibiting a higher proportion of land leveling project and property rights adjustment. The impact of the new entities-led mode on the cultivated land fragmentation were significantly better than that of the government-led mode. 3) Compared with the mountains, rural land consolidation projects in plain areas performed better in reducing cultivated land fragmentation. In conclusion, it suggests to continue and promote the government-led mode and the new entities-led mode, and improve the regional modes of rural land consolidation combining with the regional natural resources, agricultural industrial distribution and location advantages, in order to promote the high-quality development of modern agriculture.
