摘要: 使用非期望产出SBM模型、相关性分析模型和重心模型等研究方法,测评2010—2018年重庆市农业生态效率、各年份重庆市农业生态效率空间分布的相关性和农业生态效率重心时空演化轨迹。结果表明,2010—2018年重庆市各年份农业生态效率呈波动上升趋势,农业生态效率空间分布由负相关性转变为正相关性,农业生态效率的重心偏移呈螺旋状均散落在重庆市长寿区。

Abstract: Undesired output SBM model, correlation analysis model and center of gravity model were used to evaluate the agricultural ecological efficiency of Chongqing City from 2010 to 2018, the correlation of the spatial distribution of agricultural ecological efficiency in Chongqing in each year, and the evolution of the gravity center of agricultural ecological efficiency. The results showed that, from 2010 to 2018, the average value of agricultural ecological efficiency in Chongqing City had fluctuated upward, and the spatial distribution correlation of agricultural ecological efficiency had changed from a negative correlation to a positive correlation. The shift of the gravity center of agricultural ecological efficiency presented a spiral shape and was scattered in the Changshou District of Chongqing City.

Key words: agricultural ecological efficiency, undesired output SBM model, center of gravity model, correlation analysis, Chongqing City
