基于因子分析和DEA方法的日光温室不同种植模式综合效益评价

Evaluation on efficiency of different planting patterns in greenhouse based on factor analysis and DEA

为进行日光温室综合效益评价,采用了因子分析与DEA相结合的方法。以山东省寿光市2012年日光温室不同种植模式的投入产出为研究对象,借助DEA的BCC-I模型,得到了不同种植模式的综合效率、纯技术效率及规模效率,通过对技术效率较低的生产者进行生产优化以达到最优效益。

In order to evaluate the efficiency of the greenhouse,this study used factor analysis and DEA method to evaluate the comprehensive efficiency of different planting patterns in greenhouse. This study chose the input-output of different planting patterns in Shouguang City as the research object,and got the comprehensive efficiency,technical efficiency and scale efficiency by using BCC-I mode of DEA. And then the inefficient producers were optimized to achieve optimal efficiency.
