安徽省农用地利用效率测度及区域差异分析

2000年以来，安徽省农用地利用效率呈上升趋势，总体上技术效率大于综合及规模效率，表现出农用地利用技术效率驱动模式；且农用地利用效率呈现出显著的区域差异特征，其中高值区主要分布在皖江地区，较高区主要分布在皖中地区，中值区主要分布在皖北地区，而低值区主要分布在皖西南地区；影响因素上，人均GDP>有效灌溉面积>财政支农>受灾面积，并且它们的综合作用影响农用地利用效率区域差异产生及演化。建议从提高农业规模经营、强化农业科技投入、创新农业发展体制等方面提升安徽省农用地利用效率。

Measure of Farmland Utilization Efficiency and Regional Difference in Anhui Province

Since 2000,farmland utilization efficiency in Anhui Province has been increasing. Technological efficiency, in general, is higher than overall efficiency and scale efficiency, and technological efficiency is becoming a driving force. There is a significant difference among different regions in utilization efficiency, with areas of the highest value mainly distributing in the Wanjiang region, which is followed then by the central, northern and southwest regions of the province. In terms of influence factors, GDP per capita is the most significant one affecting utilization efficiency, which is followed then by effective irrigated area, financial support for agriculture, and afflicted acreage by natural disasters. Sometimes these factors can also have a combined influence on utilization efficiency and create regional difference, and the difference might evolve. Therefore, it is necessary to promote agricultural scale management, increase scientific and technological investment in agriculture, and innovate agricultural development system in order to further improve farmland utilization efficiency.
