提高农业生产效率对保障农业可持续发展和推进国家农业现代化发展战略具有重要意义.选取皖北地区35个区(县)作为决策评价单元,运用三阶段DEA模型测度皖北地区农业生产效率的真实水平,结合空间自相关模型展示皖北农业生产效率的空间集聚效应.研究结果表明:从时间序列上看,皖北地区整体的农业生产效率呈现波动轻微下滑趋势,研究前期的农业生产效率水平普遍优于后期,调整后处于技术效率前沿面的区(县)增多.人均GDP成为农业生产效率提高的有利因素,农林水事务支出和第三产业占比对农业生产效率既有正向作用也有负向作用.从全局空间上看,除2017年,其余年份皖北农业生产效率均存在明显的空间正相关性和空间集聚现象.从局部空间上看,皖北农业生产效率的空间集聚效应随时间变化在不断减弱,且空间分布格局以同类集聚分布("高-高"型或"低-低"型)为主.基于此,研究探讨皖北地区真实的农业生产效率水平及其空间分布特性对后续思考皖北农业生产发展路径具有一定意义,以期为精准改善皖北地区农业生产现状及完善相应的农业发展政策措施提供理论依据.
Agricultural Productivity and Its Spatial Pattern Evolution in Northern Anhui Province from the Perspective of County
Improving the efficiency of agricultural production is of great significance to ensure the sustainable development of agriculture and promote the national strategy of agricultural modernization.In this paper,35 districts(counties)in northern Anhui were selected as the decision evaluation unit,the real level of agricultural production efficiency in northern Anhui was measured by three-stage DEA model,and the spatial auto-correlation model was combined to show the spatial agglomeration effect of agricultural production efficiency in northern Anhui.The results show that:from the perspective of time series,the overall agricultural productivity in north Anhui showed a slight downward trend.The level of agricultural productivity in the early stage of the study was generally better than that in the later stage,and the number of regions(counties)in the forefront of technical efficiency increased after adjustment.Per capita GDP has become a favorable factor for the improvement of agricultural production efficiency,and the expenditure on agriculture,forestry and water affairs and the proportion of tertiary industry have both positive and negative effects on agricultural production efficiency.From the perspective of global space,except for 2017,there were obvious spatial positive correlation and spatial agglomeration of agricultural production efficiency in northern Anhui in other years.From the perspective of local space,the spatial agglomeration effect of agricultural production efficiency in northern Anhui was weakening with the change of time,and the spatial distribution pattern was dominated by the same agglomeration("high-high"or"low-low"type).Based on this,the study of the real level of agricultural production efficiency and its spatial distribution characteristics in northern Anhui has certain significance for subsequent thinking about the development path of agricultural production in northern Anhui,in order to provide a theoretical basis for accurately improving the current situation of agricultural production in northern Anhui and perfecting corresponding policies and measures for agricultural development.
