我国蔬菜生产技术效率分析

为判断、比较各省(自治区、直辖市)蔬菜生产技术效率,采用DEA与超效率DEA方法,对30个省(自治区、直辖市)的14个蔬菜品种(或种植模式)超效率得分、规模效益、投入冗余等进行计算、分析.结果表明:各个省(自治区、直辖市)蔬菜生产技术效率存在很大差异;省(自治区、直辖市)内不同蔬菜品种(或种植模式)生产技术效率水平存在差异;各个省(自治区、直辖市)蔬菜生产超效率得分排名与蔬菜播种面积排名大相径庭;279个DMU中,71.68%的DMU呈规模报酬递增,13.26%的DMU呈规模报酬递减,15.05%的DMU规模报酬不变;目前我国蔬菜生产要素投入及配置不合理,并提出相应的对策和建议。...

Summary:为判断、比较各省(自治区、直辖市)蔬菜生产技术效率,采用DEA与超效率DEA方法,对30个省(自治区、直辖市)的14个蔬菜品种(或种植模式)超效率得分、规模效益、投入冗余等进行计算、分析.结果表明:各个省(自治区、直辖市)蔬菜生产技术效率存在很大差异;省(自治区、直辖市)内不同蔬菜品种(或种植模式)生产技术效率水平存在差异;各个省(自治区、直辖市)蔬菜生产超效率得分排名与蔬菜播种面积排名大相径庭;279个DMU中,71.68%的DMU呈规模报酬递增,13.26%的DMU呈规模报酬递减,15.05%的DMU规模报酬不变;目前我国蔬菜生产要素投入及配置不合理,并提出相应的对策和建议。

vegetable production, technical efficiency; DEA; super efficiency DEA
In order to made reasonable judgment, comparison of the vegetable production technical efficiency of 30 provinces (autonomous regions and municipalities directly under the central government),used DEA and super efficiency DEA method, calculated and analysed 30 provinces (autonomous regions and municipalities directly under the central government), 14 varieties of vegetables (or planting patterns) 's super efficiency score, scale efficiency, input redundancy, The results showed that: There were considerable differences in the local vegetable production technical efficiency of the provinces (autonomous regions and Direct-controlled municipality); Different varieties of vegetables (or planting patterns) production technical efficiency level of the provinces (autonomous regions and Direct-controlled municipality) in were differences; The provinces (autonomous regions and Direct-controlled municipality) 's vegetable production super effi
