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.
