【摘要】 本文在效率和比较优势理论的指导下,采用理论与实证分析、定性与定量分析、静态与动态相结合的研究方法分析了湖南省主要农产品的技术效率及变化过程。在此基础上,把湖南的主要农产品生产效率与其他农业生产大省进行了对比,并进一步分析了我省主要农产品的比较优势情况,探讨了如何提高我省主要农产品的技术效率及比较优势的措施和建议。论文的主要内容有:1、阐述了效率研究的两种最主要的研究方法,数据包络分析和随机前沿分析的分析方法及国内外发展历程。简要介绍了全要素生产率、技术效率、技术进步等重要概念。2、动态的分析了1998-2007年湖南主要农产品的生产情况,并利用Malmquist指数测算了湖南省主要农产品的全要素生产率情况。结果发现,只有苎麻的全要素生产率小幅下降,其余农产品都一定程度的上升,柑橘的上升比较明显,这主要是技术进步所带来的。3、采用数学模型对农业技术在实践中的应用进行了有益的探索和实践。以自然资源、生态环境等为约束条件,以农业生产收益最大化为目标,建立了湖南省各主要农产品的效率研究模型,测算了湖南主要农产品技术效率,结果发现,湖南省的主要农产品技术效率还不太令人满意,与湖南省的农产品总产量在全国的地位相比,还有很大的改进空间。4、采用综合优势比较法,利用SFA测算的湖南省的主要农产品的技术效率值,计算了湖南省各主要农产品的综合比较优势。5、针对如何改进湖南省主要农产品的生产效率和比较优势提出了相关的对策和建议。更多还原

【Abstract】 Guided by the efficiency theory and comparative advantage analysis, this paper studies the technical efficiency and its change of main agricultural products of Hunan by the methods of theoretical and practical、qualitative and quantitative、static and dynamic analysis. On the basis of this framework, we compare the efficiency of Hunan with other province .Furthermore, the comparative advantages is analyzed, solution and suggestion is debated to improve the efficiency and comparative advantages by systematic investigation, the main content of this dissertation is:Chapter1 reviews the two important method of efficiency study: DEA and SFA, Gives a brief outlook of Total factor productivity、technical efficiency and technical progress.Chapter2 studies the production status of the main agricultural product from 1998-2007 in view of dynamics.the results shows that only the TFP of ramie goes down while other product rises and this situation is mainly promoted by technical progress.Chapter3 explores the application of agricultural technique into practice by using the mathematical model.we build the mode of efficiency study and calculate the technical efficiency of the main products of Hunan under the constraint conditions such as natural resource、ecological environment in aim to maximize revenue in agricultural production. it shows the technical efficiency is not agreeable, it still has room for improvement compared with the status of Hunan in china.Chapter4 computers the scores of technical efficiency of main product by the way of profound comparative advantages from the technical efficiency.Chapter5 provides some countermeasures and solutions of how to improve the production efficiency and comparative advantage of main agricultural product in Hunan.更多还原
