湖北省柑橘产业生产效率的DEA分析

采用数据包络分析法及我国2005—2010年柑橘生产成本和收益数据,对湖北省柑橘生产效率与其他三大主产区及全国平均生产效率进行了分析。结果表明,湖北、湖南、广东、福建四大主产区柑和桔全要素生产率呈现出明显的周期性波动;湖北省柑生产的全要素生产率变化主要源于综合技术效率变动和技术进步的共同作用,湖北省桔生产的全要素生产率变化主要源于综合技术效率的变动;湖北省柑和桔生产的规模效率变动决定了综合技术效率的变动,全国柑和桔生产的规模效率和纯技术效率变动共同影响了综合技术效率的变动。

DEA Analysis on Citrus Production Efficiency in Hubei Province

This paper uses DEA method and production cost and benefit data of citrus from 2005 to 2010 to analyze the citrus production efficiency between Hubei and other three main producing areas as well as national average level . The result shows that the TFP in four main areas of Hubei, Hunan, Guangdong and Fujian provinces have demonstrated obvious periodic fluctuation. TFP of citrus reticulata in Hubei province depends on efficiency variation and technical advances, while TFP of tangerine in Hubei depends on efficiency variation. The efficiency variation of citrus reticulata and tangerine in Hubei is determined by scale efficiency variation, and the efficiency variation of citrus reticulata and tangerine in the whole country depends on scale efficiency and pure technical efficiency together.
