摘要:

基于DEA和Malmquist TFP指数模型方法研究分析2000~2008年我国省域和区域层面农地非农化效率及其变化,为优化土地利用提供参考。研究结果表明:(1)省域层面各项平均效率水平一般,超过80%的省份农地非农化综合效率未达到有效状态;(2)农地非农化效率总体呈现东部地区>东北地区>中部地区>西部地区的状态,区域差距呈现缩小趋势;(3)农地非农化平均综合效率的提升主要源于纯技术效率的贡献,而生产效率的明显改善得益于技术进步;(4)东部和东北地区农地非农化综合效率有所下降,中西部地区综合效率呈现上升趋势,西部地区上升显著。通过研究发现:现阶段我国农地非农化存在要素资源的利用不充分现象,效率提升潜力较大;西部地区农地非农化规模集聚能力与其他地区差距较大;东部地区存在农地非农化效率损失;虽然中西部地区农地非地化效率变化提升明显,但能否成为农地非农化指标增加的依据还值得进一步探讨

Abstract:

The purpose of the paper is to study provincial and regional farmland conversion efficiencies and their changes in China from 2000 to 2008, in order to provide references for optimizing land use. Methods of DEA model and Malmquist TFP index were employed. The results indicated that: (1) on provincial level, average efficiencies of farmland conversion were not high, and more than 80% of the provincial regions have not yet achieved validity in comprehensive efficiency; (2) farmland conversion efficiencies basically showed the trend of eastern regions> northeast regions> central regions> western regions, and regional difference has decreased; (3) the rise of average comprehensive efficiency of farmland conversion on provincial level was mainly due to the contribution of pure technical efficiency, and the significant improvement of production efficiency benefited from technical change; (4) the comprehensive efficiency of farmland conversion of eastern and northeast regions has decreased, while that of central and western regions has increased, with significant rise in western regions. The study found that: at the present stage, there is insufficient utilization of farmland conversion input in China, and the potential for efficiency enhancement is huge; there is a large gap in the ability of scale concentration between western regions and other regions; eastern regions are facing efficiency loss in farmland conversion; although farmland conversion efficiencies in central and western regions has increased significantly, whether it could be used as the evidence for increasing farmland conversion quota needs further research.
