Empirical Analysis of Spatio-Temporal Evolution of Agricultural Land Allocation Efficiency and Driving Factors in China Based on All-encompassing Approach to Food. (English)

[Objective] The spatial and temporal evolution and driving factors of agricultural land allocation efficiency were analyzed in order to provide theoretical support and scientific reference for the practice of the all-encompassing approach to food, the effective utilization of agricultural resources and the high-quality development of agriculture. [Methods] The article was based on the concept of the all-encompassing approach to food. Using a three-stage data envelopment analysis (DEA) model, Dagum’s Gini coefficient, kernel density estimation and panel Tobit regression, the article measures the allocation efficiency of agricultural land in 30 provinces in China from 2004 to 2022, and analyzed the characteristics of the spatial and temporal evolution and the driving factors. [Results] The overall level of agricultural land allocation efficiency in China was high and stable, and after removing the effects of environmental factors and random errors, the spatial characteristics of allocation efficiency were reversed, and eventually showed a decreasing trend of central-northeastern-eastern-western; and the overall differences between regions showed a fluctuating upward trend, with hypervariable density dominating the overall differences; There was some spatial polarization phenomenon in all regions; urbanization rate, ecological governance, agricultural technology progress had a significant positive effect on the allocation efficiency of agricultural land, rural road facilities and residents’ food and nutritional needs had a significant negative effect, and the effect of financial support for agriculture was not significant. [Conclusion] We should correctly understand and exert the influence of food consumption structure on the allocation of agricultural land, deeply implement the practice of green ecological agriculture, and realize the organic combination of the government and the market, so as to improve the efficiency of agricultural land allocation in all aspects.

[目的] 探讨农地配置效率时空演变与驱动因素, 为践行大食物观、农业资源有效利用及农业高质 量发展提供理论支撑和科学参考。[方法] 基于大食物观理念, 本研究运用三阶段 DEA 模型、Dagum 基尼 系数、核密度估计法和面板 Tobit回归, 对 2004—2022 年中国 30 个省份农地配置效率进行测度并分析其 时空演变特征及驱动因素。[结果] 中国农地配置效率总体水平较高且稳定, 剔除环境因素和随机误差后, 配置效率的空间特征发生逆转, 并最终呈现出中部—东北—东部—西部依次递减的变化态势; 且区域间总 体差异呈波动上升趋势, 其中超变密度在总体差异中占主导地位; 各区域的农地配置效率均存在一定的空 间极化现象; 城镇化率、生态治理、农业技术进步对农地配置效率有显著正效应, 农村公路设施和居民食物 营养需求呈显著负效应, 财政支农的效应不显著 。[结论] 应正确理解和运用大食物观理念, 发挥食物消 费结构对农地配置的影响、深入实施绿色生态农业实践、实现政府和市场有机结合, 全方位提高农地配置 效率。 [ABSTRACT FROM AUTHOR]
