Abstract

In many parts of the world, the shortage of cultivated land and the food crisis are worsening on a continued basis. Hence, the central and local governments of the PRC have successively issued various related policies to encourage the practice of farmland transfer, promote the eco-friendly utilization of cultivated land, and ameliorate the efficiency of cultivated land utilization. Under the context of large-scale farmland transfer and rural revitalization strategy in China, it is significant to ensure agricultural sustainability through the coordination of farmland transfer and the amelioration of cultivated land green utilization efficiency (CLGUE). In the present study, 30 Chinese provinces were taken as the research object, with the super-efficient SBM model, the coupling coordination degree model and the spatial analysis model applied in combination. Based on the measurement of CLGUE, a thorough analysis was conducted to explore the evolution of coordination degree in regard to farmland transfer and CLGUE in China from both spatial and temporal perspectives. The conclusions drawn from this study are as follows. Firstly, the overall CLGUE exhibited an upward tendency in the PRC, from 0.440 in 2005 to 0.913 in 2019, with a yearly growth rate of 5.47% on average. However, there were significant spatial disparities in CLGUE between different regions and provinces. Secondly, there was a steady increasing trend shown by the level of coordination degree regarding farmland transfer and CLGUE across China. Further, due to the variation in natural and economic conditions, there were significant spatial-temporal disparities in the coordination degree among these 30 provinces. Lastly, there were obvious spatial aggregation patterns at the provincial level regarding the coordination degree in farmland transfer and CLGUE across China. However, there was a declining trend in the level of spatial aggregation patterns for coordination degree.

摘要

在世界许多地区,耕地短缺和粮食危机持续恶化。因此,中国中央和地方政府相继出台了各种相关政策,鼓励耕地流转,促进耕地的生态友好利用,提高耕地利用效率。在中国大规模耕地流转和乡村振兴战略背景下,协调耕地流转与耕地绿色利用效率(CLGUE)的改善,确保农业的可持续性具有重要意义。本研究以中国 30 个省份为研究对象,采用超效率 SBM 模型、耦合协调度模型和空间分析模型相结合的方法,对 CLGUE 进行了测算,从时空角度深入分析了中国耕地流转与 CLGUE 协调度的演变。研究结果表明:①中国 CLGUE 整体呈上升趋势,由 2005 年的 0.440 上升至 2019 年的 0.913,年均增长率为 5.47%;但不同地区和省份间 CLGUE 存在显著的空间差异。②中国耕地流转与 CLGUE 的协调度水平呈稳步上升趋势,由于自然和经济条件的差异,30 个省份的协调度存在显著的时空差异。③中国耕地流转与 CLGUE 的协调度在省级水平上存在明显的空间集聚模式,但协调度的空间集聚水平呈下降趋势。
