| Abstract: |
| To further realize the development status of China's citrus industry, based on the DEA model method, the input and output efficiency of China’s citrus industry from 1996 to 2011 were measared and analyzed. Research results were as follows: from 1996 to 2011, the comprehensive technical efficiencies of the input and output of China’s citrus industry were high overall, while the input and output efficiencies presented a volatile trend, which was roughly divided into two phases by 2002, showing down first and then up; due to the unsound input and output structure and scale and that institutional mechanism reform had big influence on China爷s citrus industry, the input and output efficiencieies of some years were not DEA effective; main production and direct operating cost were main influencial factors of the input and output efficiencies of China’s citrus industry. Therefore, the corresponding improving suggestions were put forward, such as reducing the market volatility of citrus production inputs or output factors, inhibiting of the blind expansion of production scale, valuing the economic benefits especially the farmers’income, and the reasonable and effective configuration of various inputs. |
