农产品成本收益评价方法的探讨——数据包络分析的应用

RESEARCH ON APPRAISAL METHODS FOR COST AND PROFIT OF AGR-PRODUCTS THE APPLICATION OF DATA ENVELOPMENT ANALYSIS

评价农产品成本收益的方法很多，但往往缺乏分析的深度与客观性，一种崭新的统计方法——数据包络分析——已经逐步应用于投入产出的规模、结构与技术有效性等的测定．文章介绍了数据包络分析（ＤＥＡ）的模型、论述其特点、应用与计算方法，作为实例探讨了其中的Ｃ２ＧＳ２模型如何应用于农产品成本收益的技术有效性评价，并指出有关的计算机分析软件．

There are many appraisal methods for cost and profit of agr products,but they often lack depth and objectiveness. In this article, we introduce a model,disucss the characteristics and computing of Data Envelopment Analysis (DEA),which is used widely to compute the scale,structure and technical efficiency of input and output,etc. As an applicantion of DEA,we use the model of C 2GS 2 one of the models from DEA, to compute the technical efficiency for cost and profit of agr-products.
