摘要:

目的 高标准农田建设是推进耕地数量、质量、生态“三位一体”保护的关键举措，探究高标准农田建设对耕地多功能利用水平的影响，以期为实现耕地资源可持续利用提供参考。方法 文章基于湖北省部分县市的农户调研数据，运用双重差分法探究高标准农田建设对耕地多功能利用水平的影响效应及内在机制。结果 （1）高标准农田建设能够有效提升耕地多功能利用水平，并促进耕地多功能的耦合协调，影响系数分别为0.050和0.021，且多种检验均显示研究结果稳健。（2）高标准农田建设通过推进耕地规模经营、促进农业技术进步和加速农村产业融合三条路径来提升耕地多功能利用水平，影响系数分别为5.183、11.897和0.523。（3）高标准农田建设对小规模农户和适度规模农户耕地多功能利用水平的影响系数分别为0.020和0.077，两者相比，适度规模农户的提升作用更大；平原和丘陵地区高标准农田建设分别对耕地多功能利用水平的影响系数为0.077和0.027，两者相比，平原地区的提升效果更为明显。结论 高标准农田建设应将提高耕地多功能利用水平作为核心理念，立足于农业规模化、机械化、产业化发展，充分虑及耕地利用的差异性和空间分异特征，因地制宜走好差异化、特色化、生态化发展道路，全方位筑牢“三位一体”的耕地保护根基。

Abstract:

The construction of high-standard farmland is an important measure to promote the protection of quantity, quality and ecology of cultivated land, and is of great significance for realizing the sustainable utilization of cultivated land resources. Based on the research data of farmers in some counties of Hubei province, the difference-in-differences model was applied to investigate the effect and internal mechanism of high-standard farmland construction (HFC) on cultivated land multifunctional utilization level (CLMUL). The results showed that: (1) HFC could significantly improve CLMUL and promote the coupling and coordination of cultivated land multi-functions. The coefficients of influence of HFC on LMUL were 0.050 and 0.021, respectively. After conducting a series of robustness tests, the regression conclusions remained valid. (2) HFC lifted CLMUL by promoting the scale management of farmland, the progress of agricultural technology and the integration of rural industries. The coefficients of influence of HFC on the scale management of farmland, the progress of agricultural technology and the integration of rural industries were 5.183, 11.897, and 0.523, respectively. (3) The impact coefficients of HFC on CLMUL by small-scale farmers and moderate-scale farmers were 0.020 and 0.077, respectively. Compared with small-scale farmers, moderate-scale farmers had a greater role in upgrading. The impact coefficients of HFC on CLMUL in the plains and the hilly areas were 0.077 and 0.027, respectively. Compared with the hilly areas, the upgrading effect in the plains was more apparent. Therefore, HFC should promote CLMUL as the core concept, strengthen the large-scale, mechanized and industrialized development of agriculture, take into account the difference and spatial differentiation characteristics of cultivated land use, affirm its pursuit of differentiated, characteristic and ecological development in accordance with local conditions, and lay the foundation of the quantity, quality and ecology conservation of cultivated land.
