长江经济带是我国经济快速发展地区,也是我国重要的粮食产区,分析其耕地利用效率状况对于兼顾经济发展、保障粮食安全具有重要的现实意义。本研究借助超效率SBM模型对2008—2017年长江经济带126个地级市的耕地利用效率进行测度,揭示其时空演变特征,从要素投入视角提出了未来耕地利用效率的改善方向。研究表明:1)研究期长江经济带耕地利用效率呈波动下降态势,整体效率不高,区域差异明显。空间分布上呈显著集聚特征,其中高效率区主要集中在江苏东部沿海地区,低效率区主要集中在贵州大部和湖南西部等区域。2)研究区耕地利用效率与冗余率呈显著负相关,耕地生产投入要素均存在冗余情况,尤其是农业从业...

Being an important grain-producing area in China, the Yangtze River economic belt experienced a rapid economic development. It is of great practical significance to analyze the farmland utilization efficiency for balancing economic development and ensuring grain security. Applying the super-efficiency SBM model, this paper calculated the farmland utilization efficiency in 126 prefecture-level cities in the Yangtze River economic belt from 2008 to 2017 to reveal its spatial and temporal evolution characteristics, to put forward future direction of improving farmland utilization efficiency from ...
