安徽省农业生态效率时空演化及影响因素研究

The spatiotemporal evolution and influencing factors of agricultural ecological efficiency in Anhui Province

利用数据包络分析、回归分析等方法,分析2008年至2020年安徽省农业生态效率的时空演化及其影响因素。主要结论如下:1)安徽省农业生态效率整体呈上升趋势:从2008年至2020年,该省农业生态效率由0.56提高到1.21;但不同地区之间的差异较大:东部地区的农业生态效率普遍高于中西部地区。2)农业生态效率与农民收入水平、农业机械化水平、农膜使用量等因素密切相关,其中农民收入水平和农膜使用量对安徽省农业生态效率的影响最为显著。本研究结果可以为政府制定相关农业生态政策提供有益的参考。

Using data envelopment analysis and regression analysis,this paper analyzed the temporal and spatial evolution of agricultural eco-efficiency and its influencing factors in Anhui Province from 2008 to 2020.The main conclusions were as followsings.1)Agricultural eco-efficiency in Anhui Province showed an overall upward trend,from 2008 to 2020,it increased from 0.56 to 1.21,but there was a big difference among different regions,and the agricultural eco-efficiency in eastern region was generally higher than that in central and western regions.2)Agricultural ecological efficiency was closely related to the income level of farmers,the level of agricultural mechanization,and the amount of agricultural film used,among which the income level of farmers and the amount of agricultural film used had the most significant impact on the agricultural ecological efficiency in Anhui Province.The results of this study can provide useful reference for the government to formulate relevant agro-ecological policies.
