| 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) 耶s vegetable production super efficiency score ranking and vegetable planting area rankings were very different; In the aggregate of 279 DMU, 71.68% of the scale of DMU were increasing, return 13.26% of the scale of DMU were diminishing returns, 15.05% of the DMU scale for the same; At present, China's vegetable production inputs and configuration was not reasonable, and put forward the corresponding countermeasure and the suggestion in the final. |
