安徽省县域耕地利用效率时空分异格局分析

Analysis of Spatial and Temporal Variation Patterns of Cultivated Land Use Efficiency in Counties of Anhui Province

以安徽省61个县域为研究对象,构建耕地利用效率评价指标,运用DEA-BBC模型和Malmquist指数测度2011—2017年安徽省县域耕地利用效率水平,并利用探索性空间数据方法(ESDA)分析安徽省县域耕地利用效率时空分异格局。研究表明:总体上安徽省县域耕地利用效率提高,耕地利用效率的全要素生产率增长主要动力是技术进步,省域范围内耕地利用效率的极化现象较明显,工业化水平等是影响耕地利用效率的关键因素。

This paper takes 61 counties in Anhui Province as the research objects,constructs evaluation indicators of cultivated land use efficiency and measures the level of cultivated land use efficiency in counties in Anhui Province from 2011 to 2017 using DEA-BBC model and Malmquist index.And it also analyzes the spatio-temporal divergence pattern of cultivated land use efficiency in counties in Anhui Province by means of exploratory spatial data approach(ESDA).The study shows that the efficiency of cultivated land use in Anhui province counties has improved.The main driver of total factor productivity growth in cultivated land use efficiency is technological progress.The polarization of cultivated land use efficiency within the province is more obvious,and the level of industrialization is the key factor affecting cultivated land use efficiency.
