摘要:

目的 农业生态效率是衡量中国式农业现代化水平的重要标尺，也是构建现代化大农业话语体系和推进农业强国建设的关键环节。长江经济带与黄河流域作为我国农业生态化的核心地和先行区，科学测度其农业生态效率及异质性来源十分必要。方法 文章运用SBM模型、Dagum基尼系数法、核密度估计、地理探测器等方法，利用2000—2022年相关数据考察了长江经济带和黄河流域农业生态效率的时空演变格局及其驱动因素。结果 （1）长江经济带的农业生态效率要低于黄河流域，但其增长势头更为强劲。（2）长江经济带农业生态效率呈现出由“离散零星”向“极化”持续演进的空间格局，而黄河流域则具有典型的集中连片分布特征。（3）两大区域农业生态效率由区域失衡向区域均衡转变态势不断趋强，但黄河流域的极化现象更为明显。（4）经济社会发展程度和人均农业增加值对两大区域农业生态效率的影响是同向的，但人均农业增加值对长江经济带农业生态效率的影响更为显著，农业规模化水平则对黄河流域农业生态效率的空间分异更具解释力。结论 开辟了区域联动发展的新思路新赛道，能够在为推动构建绿色发展机制贡献力量的同时，形成可借鉴可复制可推广的探索性经验。

Abstract:

Agricultural ecological efficiency serves as a critical benchmark for measuring the level of Chinese-style agricultural modernization and plays a pivotal role in constructing the discourse system of modern large-scale agriculture and advancing the development of an agricultural powerhouse. As the core regions and pioneer zones for agricultural ecologicalization in China, the Yangtze River Economic Belt and the Yellow River Basin play a crucial role. Therefore, it is imperative to scientifically evaluate their agricultural ecological efficiency and identify the sources of heterogeneity. This research employed methods including the SBM model, the Dagum Gini coefficient method, kernel density estimation, and geographical detector, leveraging relevant data spanning from 2000 to 2022 to investigate the spatial-temporal evolution patterns and driving factors of the agricultural ecological efficiency in the Yangtze River Economic Belt and the Yellow River Basin. The research indicated that: (1) The agricultural ecological efficiency of the Yangtze River Economic Belt was lower than that of the Yellow River Basin, yet it exhibited stronger growth momentum. The agricultural ecological efficiency of the Yangtze River Economic Belt demonstrated a spatial pattern evolving continuously from "discrete and sporadic" to "polarized." In contrast, the Yellow River Basin displayed typical characteristics of concentrated and contiguous distribution. (2) The trend of agricultural ecological efficiency in the two major regions shifting from regional imbalance to regional balance was becoming increasingly pronounced; however, the polarization phenomenon within the Yellow River Basin remained more evident. (3) The degree of economic and social development, as well as the per capita agricultural added value, exerted a same-directional impact on the agricultural ecological efficiency in the two major regions. However, the per capita agricultural added value exerted a more significant impact on the agricultural ecological efficiency of the Yangtze River Economic Belt, while the level of agricultural scale demonstrated stronger explanatory power regarding the spatial differentiation of the agricultural ecological efficiency in the Yellow River Basin. This study has not only generates novel insights and innovative pathways for regional coordinated development but also contributes to the advancement of a green development mechanism. Moreover, it can also generate exploratory experiences that serve as valuable references and can be replicated and promoted.
