基于DEA理论与模型的中国西部地区农用地利用效率评价

Evaluation of Agricultural Land Use Efficiency in China's Western Based on DEA Theory and Model

运用DEA(数据包络分析)方法,基于农用地投入/产出分析,构建评价指标体系,对我国西部地区农用地利用效率进行评价,旨在揭示西部十二个地区农用地利用水平,指出不合理投入对农用地利用效率的影响,并为目标地区农用地利用探索集约利用的途径。DEA关于农用地利用效率的评价值显示,西部十二个地区农用地利用效率在空间上呈现出较大差异,同时,模型的运用表明,农用地利用效率受农用地利用的技术效率与规模效率共同限制,投入要素的资源的配置问题将成为未来农用地集约利用的制约因素。在农用地的利用中,提高农用地利用效率,改善农用地粗放经营的格局,必须科学规划、合理配置资源,优化结构。

This paper constructed evaluation index system based on the input-output analysis,in order to evaluated agricultural land use efficiency.Study is to reveal agricultural land use efficiency change and its reasons in the western region,and pionted out the effects of unreasonable input on output of agricultural land.According to the evaluation value of DUM about agricultural land use efficiency,showing selected agricultural land use has a large difference in different space.At the same time,based on the models,agricultural land use technical efficiency and scale restricted efficiency efficiency,and they will be constraints of agricultural land intensive use in the future.To improve agricultural land use efficiency,ameliorate the pattern of extensive management of agricultural land,must be scientific planning,rational distribution of resources,optimizing the structure.
